【摘要】 利用RS和GIS技术对2000、2005和2008年遥感影像数据进行人机交互解译,建立了2000—2008年浙江省耕地动态数据库,并运用岭回归分析法研究了耕地变化的驱动力及其特征.结果表明:2000—2008年间,浙江省耕地变化较剧烈,2000—2005、2005—2008年,研究区耕地年动态度分别为-1.42%和-1.46%,耕地主要流向城乡工矿居民用地.非农人口比例、房地产开发投资、城市绿化面积和果园面积构成了浙江省乃至我国东部发达地区耕地变化的主要驱动因素.更多还原

【Abstract】 Through the human-computer interactive interpretation of the 2000,2005,and 2008 remote sensing images of Zhejiang Province with the help of RS and GIS techniques,the dynamic database of cultivated land change in the province in 2000-2008 was established,and the driving factors of the cultivated land change were analyzed by ridge regression analysis. There was a notable cultivated land change in the province in 2000 -2008. In 2000 -2005 and 2005-2008,the annual cultivated land change in the province arrived -1. 42% and -1. 46% ,respectively,and most of the cultivated land was changed into residential and industrial land. Non-agricultural population rate,real estate investment,urban green area,and orchard area were thought to be the main driving factors of the cultivated land change in Zhejiang Province,and even,in the developed areas of east China.更多还原
