An Approach Confirming The Representative Regions of an Agroecological Experimental Station--A Case Study from Changwu Agroecological Exprimental station
论农业生态试验站可辐射区域的定界--以长武试验站为例

In this paper with Changwu Agro-ecological Experimental Station as an example and based on the information from Chinese agricultural comprehensive divisions,the probable representative regions of an agroecological experimental station was studied with county as elementary unit. Through analysis of the regional features,thirteen identification factors were screened. The relative important extent of every factor was put in order by using the analytic hierarchy process.Then fuzzy dicernment was carried out based on the standardization of the data range,and the closeness degrees between Changwu and every screened county were calculated.According to the principle of choosing closeness the representive region of Changwu Agro-ecological Experimental Station was confirmed.
