Comprehensive Evaluation and Analysis on Spatiotemporal Variation of Cultivated Land on Provincial Scale Based on GIS——A Case Study in Guizhou Province
摘要
Abstract
Cultivated land quality is essential to national food safety,as well as the sustainable development of social economy and eco-environment.Thus,strengthening cultivated land protection plays a significant role in reality.Typically,the protection is conducted by two techniques,as cultivated land evaluation and spacetime evolution analysis.An empirical research had been done on the change of cultivated land in Guizhou Province from 1989 to 2010 through the application of GIS spatial analysis technology which involved in the evaluation index system of cultivated land quality,the combination of cultivated land optimization model and ideal point method,relative change rate was used to explore the quality and spatiotemporal evolution of cultivated land.The results showed that during that period,the quality of cultivated land in Guizhou was improved obviously and the area of which increase to 9 202.69 km2 including the first-class cultivated Land 7 854.11 km2,the second-class cultivated Land 2 054.80 km2 and the third-class cultivated land 1 273.09 km2.Moreover,it was pointed out that farmland soil,slope configuration,water loss and soil erosion,‘Four Modernization’ process,land exploitation,construction,cultivated land protection,returning farmland to forest project,public opinion and natural,economic and social factors were the main elements to drive the change on cultivated land quality and spatiotemporal form.关键词
