论农业生态试验站可辐射区域的定界--以长武试验站为例

An Approach Confirming The Representative Regions of an Agroecological Experimental Station--A Case Study from Changwu Agroecological Exprimental station

摘要: 本文以长武农业生态试验站为例，参照全国综合农业区划结果，以县为基本单位，初选试验站可能代表范围。通过区域特征分析，筛选识别因子；并用层次分析法，对各因子相对重要程度排序。在数据极差标准化基础上，进行Fuzzy识别，逐一计算初选县与长武贴近度。根据择近原则，确认试验站可以代表的范围。

Abstract: 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.
