INVESTIGATION INTO EVALUATION OF AGRICULTURE INFORMATIZATION LEVEL BASED ON TWO-TUPLE

. Agriculture informatization level is an important part of one country’s modernization. It is important to construct reasonable agriculture informatization evaluation indicator system and propose the evaluation method for promoting the agriculture informatization. This paper firstly analyzes the research status of the indicator system and evaluation method of informatization at home and abroad. On the basis of the relative literatures, the evaluation indicator system of the agriculture informatization in China is constructed, and the evaluation model of the agriculture informatization based on two-tuple and the relative operators are also constructed. This model not only can be used to rank the orders of the different areas according to the informatization level, but also can realize the qualitative evaluation of the agriculture informatization of the different areas according to the evaluation system. Finally, the application example shows that the evaluation system of the agriculture informatization constructed in this paper is effective, and the evaluation method proposed in this paper is simple and easy to use.


Introduction
Agriculture informatization plays the key role in the process of achieving agriculture modernization, and the development of agriculture modernization must include the process of agriculture informatization. Based on the comprehensive development in the filed of agriculture and the application of modern information technology and information system, agriculture informatization provides the effective information support for the agricultural production-supply-marketing and the related management and service, in order to improve indicators (i.e. rural industry informatization, rural administrative management informatization, rural living consumption informatization and rural social resource informatization).  evaluated the informatization level from several aspects, such as the construction of information system hardware, information quantity of rural information system, the scale and quality of information promulgated by the web site, timeliness of information. Sheng (2005) evaluated the informatization level from six aspects, such as agriculture information resource, agriculture information infrastructure, the application of agriculture information and technology, agriculture information industry, agriculture information talents and external environment of agriculture informatization.
There are many informatization evaluation methods, such as method of the principal components analysis (Zhang 2006), multiple criteria method COPRAS (Kaklauskas et al. 2010), Grey Criteria Method , Data Envelopment Analysis (DEA) (Hou 2005), the Fuzzy Synthetical Evaluation Method (Li and Luo 2005), comprehensive evaluation method Based on Analytic Hierarchy Process (AHP) and Gray Relation Analysis Method (Yang 2006), evaluation method based on Neural Network and so on. But only Sheng (2005) used the AHP method to evaluate the rural informatization.
Many decision makers are more inclined to express their opinions with linguistic information, owing to the complexity of objective circumstances and the lack of accurate decision data. On the basis of the above research, this paper proposed the directly linguistic evaluation method based on two-tuple and relative operators and established the correlative model of agriculture informatization evaluation; Finally, according to the evaluation example of agriculture informatization from four regions in Shandong province, the effective of the evaluation indicator and method is illustrated.

Introduction of evaluation indicator
Rural informatization status: rural informatization status refers to the supporting strength of the government policy, and the status of rural informatization in the construction of rural area. Rural informatization needs governmental support, especially county-township and local government's support. The basic guarantee in informatization construction in rural area includes the following aspects, such as setting up some relative rules and regulations, carrying out the corresponding planning and investment, especially constructing the infrastructure constructions. Therefore, this indicator containes the following aspects: the organization status, planning and budget, per-capita expenditure, expenditure growth rate, etc. Agriculture information infrastructure: agriculture information infrastructure mainly refers to many kinds of network. These can support the development and application of agriculture information resource, and the application of agriculture information technology, mainly including the traditional network (broadcast and television network, telephone network) and the modern network (rural economic information network). Agriculture information infrastructure is the foundation of agriculture informatization and the necessary premise that the agriculture information resource and the information technology can come into play. Agriculture informatization construction level reflects its development extent directly. Its mainly includes some following aspects: first, in the aspect of traditional network, the construction conditions can be measured based on the popularization of rural telephone and of rural television; second, modern information device, including network server, computer, switch device, router device and so on; third, service station, including the county and township proportion of setting up rural economic information service stations, the administrative villages of setting up the spot of rural economic information service and so on.
The application condition of agriculture information technology: according to widely applying modern information technology into the field of agriculture, the purpose

Index Introduction
A4 Agriculture information resource including: the transmission rate of radio and television programs concerning agriculture and economic, million person possession quantity of web site concerning agriculture per-capita agriculture library collection A5 Agriculture information talents including: the ratio of network and information technology talents to agriculture scientific research personnel, education level of rural family labor, the proportion of employee in rural economic information centre A6 Agriculture information industry including: per-capita throughput of post and telecommunication in rural area, the ratio of gross product in consultation service industry of agriculture information to rural GDP A7 Organization and management including: organization setting, regulations and rules, security management The end of Table 1 of agriculture informatization construction can promote the continuous, steady and highly efficiency development of agriculture. We may say that agriculture information technology is the core and forerunner of agriculture informatization development, and the evaluation of the present application status of agriculture information technology is an important content in the evaluation of agriculture informatization construction. This indicator will be used to evaluate the application status of superior popularization information technology, such as internet technology and database technology: the proportion of rural internet user, the possession quantity of data resource, conversion ratio of agriculture science and technology achievements, information dissemination of farm products and online trading and so on. The level of agriculture information resource: agriculture information resource is not only the essential content contained by the foundation structure of agriculture informatization, but also the remarkable symbol of the success in agriculture informatization construction. Its exploitation and utilization is the core content of agriculture informatization construction, mainly including that: first, document information resource which refers to some kinds of information saving on the medium of paper and can be evaluated by the per-capita agriculture library collection; Second, data information resource which refers to the digital information and network information resource saved on the disk and compact disk and can be evaluated by million person possession quantity of web site concerning agriculture; Third, simulation information resource which refers to the information sent in the form of television and broadcast and can be evaluated by the transmission rate of broadcast and television programs concerning agriculture and economy.
Agriculture informatization talents: professional informatization talents are the important premise of agriculture informatization construction in our nations, and the most important factors affecting the development of agriculture informatization. At present, employees in the rural economic information center are consisted of the core of agriculture information talents, and agriculture scientific research personnel are also the important components of agriculture information talent. Consequently, we selected the two indicators to evaluate this factor of agriculture information talent, which include the proportion of agriculture scientific research personnel and the employees in the rural economic information center.
The development of agriculture information industry: the development degree of agriculture information industry, to some extent, not only reflects the development level of agriculture informatization, but also directly reflects the general conditions of peasants who receive information service. At present, consultation service industry of agriculture information has a new start, and it will be the core industry of the development of agriculture information. Therefore, we choose the following two indicators to evaluate the development of the agriculture information industry: the ratio of gross product in consultation service industry to rural GDP, and per-capita throughput of post and telecommunication in rural area.
Organization and management: the development of agriculture informatization needs to be guided and managed by the government, so the level of organization and management in the process of agriculture informatization is also the vital symbol of evaluating the agriculture informatization level. This indicator is mainly used to evaluate in these aspects, such as the complete organization, the complete management system, and information security measures.

Evaluation method of agriculture informatization based on two-tuple
Two-tuple model, proposed by Herrera, the Spanish professor, is a kind of information processing method. Its character is that it can effectively avoid the problem of information loss and distortion in the process of integrating and operating linguistic evaluation information by using two-tuple to express the linguistic evaluation information, so that the calculation results of linguistic information are more precise. − be the aggregated calculation result from the elements in the set S , then we can get two-tuple concerning to β from the following function:

Correlative properties of linguistic term set
(1) It can be seen that two-tuple concerning to ( 0,1, , 1) In this formula, , , [0,1] r α β ∈ , and the rules and values of the parameters are shown in Table 2.   a a a a    . In addition, we can conclude that the informatization level in four areas is between 2 s and 3 s , and it shows little difference and has not yet reached the general level.

Conclusion
Agriculture informatization plays the key role in the process of achieving agriculture modernization; therefore, it's very important to construct the reasonable evaluation indicator system and evaluation method of agriculture informatization for understanding and accelerating the development of agriculture informatization. Less research on agriculture informatization evaluation system has been carried out in China now. In this paper, based on the correlative reference, we firstly analyze the present conditions of informatization evaluation indicator system and evaluation method, and we construct the evaluation indicator system of the agriculture informatization and the evaluation model of the agriculture informatization based on the two-tuple and relative operators. This model can not only be used to rank the order of informatization level of the different regions, but also realize the qualitative evaluation of the agriculture informatization of the different regions. Finally, an application example of the four regions in Shandong province shows that the evaluation system of the agriculture informatization constructed in this paper is effective, and the evaluation method proposed in this paper is simple and easy to use.
