基于STIRPAT模型的陕西省耕地面积变化社会经济驱动力分析
Analysis on Societal and Economic Driving Force for Changes in Area of Cultivated Land of Shaanxi Province Based on STIRPAT Model
摘要
Abstract
In recent years,the driving force for changes in cultivated land area is one of the hotspots in land-use change researches.With the cultivated land data and related socio-economic development data from 1978 to 2010,the main influencing factors were sifted by principal component analysis and stepwise regression.Afterwards,the relationship between cultivated land and main influencing factors of urbanization rate,the per capita GDP,highway mileage,total social retail sales were analyzed in Shaanxi Province by introducing STIRPAT model.The results showed that the per capita GDP was the main reason for the declining of cultivated land area.Furthermore,the increase of total social retail sales also played an important role in decrease of cultivated land area.However,the improvement of traffic condition promoted the increase of cultivated land.Meanwhile,the increase of urbanization rate made contribution to the cultivated land growth.Accordingly,several suggestions are proposed in this study to mitigate the pressure of cultivated land reduction,including urbanization level improvement,transport facilities level improvement,industrial structure adjustment and economic growth mode transition,etc.关键词
