摘要
以西安市为例,分析了其2000—2012年耕地面积变化及空间差异,并采用主成分分析法,从人口、经济、产业结构、生活水平和城镇化水平5个方面共选择14个因子,揭示了近13年来西安市耕地面积变化的作用机制,从而为制定合理的耕地保护制度和政策提供参考依据。研究结果表明:(1)西安市耕地面积总体呈逐渐下降趋势,年平均递减率为1.38%;(2)西安市耕地面积变化的主要驱动力因素是经济发展、城镇化水平、农业因素,这三者构成了西安市耕地面积变化的主要驱动力;(3)可以从减少建设用地占用、促进经济发展模式的转变和加强对农业结构调整的引导3个方面来遏制西安市耕地面积锐减的趋势。
In order to provide reference for the development of rational farmland protection system and policies,we took Xi′an City as an example,used the principal component analysis,arable land from 2000 to 2012data and related socio-economic data based on 14 factors selected from the demographic,economic,industrial structure,living standards and the level of urbanization five areas altogether,to reveal the mechanism of the change of cultivated land area in Xi′an City in the nearly 13 years.The results showed that：（1）the overall arable land of Xi′an City decreased gradually,the annual average decreasing rate was 1.38%;（2）the main driving forces on the change of cultivated land area in Xi′an City was the economic development,urbanization level,agricultural factors,which constituted the main driving forces to cultivated land change in Xi′an City;（3）meanwhile,the trend of sharp decline of arable land in Xi′an City can be curbed through these 3aspects：reduction of occupation from the construction land,promotion of economic development mode transformation and strengthening the guidance of adjustment of agricultural structure.
