基于GWR的新疆农机总动力空间异质性分析
Analyzing the Spatial Heterogeneity of Agricultural Machinery Power in Xinjiang Based on GWR
摘要
Abstract
Based on the agricultural machinery power and agricultural economy data of 85 counties and districts of Xin-jiang autonomous region from 2003 to 2012,the spatial heterogeneity of agricultural machinery power and driving factors were analyzed by using spatial analysis tools of GIS and geographically weighted regression ( GWR ) model.The results showed that the counties with higher agricultural machinery power were gathering in central region and the counties with lower were clustering in southern region of Xinjiang.Meanwhile there was a significant spatial positive correlation for agri-cultural machinery power in different counties, and the trend of correlation showed an downward trend during 2003-2012.The driving factors revealed a localization characteristic of no-stationary intercourse.The agricultural machinery power of northwestern region was mainly affected positively by total sown area, while agricultural machinery power of the southwest and south central regions were more sensitive to the government financial investment and peasants income in separately.And the reducing number of primary industry played an important role in promoting the agricultural machinery power.Therefore, this results could explain and analyze the rules and reasons of agricultural machinery power develop -ment in a more rational way.This had vital significance for boosting agricultural mechanization development in a fully and fast way.关键词
