摘要
新疆县域农业经济发展的水平存在明显的差异。文中通过建立评价新疆县域农业经济发展的指标体系,采用主成分分析法对新疆各县农业经济发展水平进行综合评价,依据所得的农民生活与生产水平、投入产出率、产值、粮食安全与经营多元化、优势产业发展集中度、农业经济结构6个主成分,聚类分析得出新疆农业经济发展水平分为6类,并利用ArcGIS 10.3软件绘制了新疆83个县(市)的发展水平空间分异图,新疆县域农业经济空间结构特征为南北两极分化,北高南低,且县域农业经济发展水平在空间上呈现出明显的相关性,发展水平相似的县域在空间上相互邻近,呈集聚分布态。
The development level of county agricultural economy exists significant differences in Xinjiang. In this study,the evaluation index system of county agriculture economic development was established by using principal component analysis to comprehensively evaluate the agricultural economic development level of counties in Xinjiang. According to the six principal components： farmers＇ life and production level,rate of input-output,output value,food security and diversification,advantage of industry concentration,and agricultural economic structure,Xinjiang agricultural economic development level was clustered into six classes,and the spatial distribution of development level differences about 83 counties were draw by Using ARCGIS 10. 3 software. Result showed that the Xinjiang county agricultural economy differentiated between the north and south areas,it was lower in the south and higher in the north,and the county agricultural economic development level presented obviously spacial correlation; the counties with similar development levels were adjacent to each other,showing concentration distribution status.
