摘要
综合运用遥感(RS)和地理信息系统(GIS)技术,提取Slope、RVI、SQI、DVI、LUD 5个因子作为评价指标.根据压力-状态-响应(PSR)框架,构建桂平市耕地资源质量评价体系,最终桂平市的耕地分为5个等级,针对不同的等级提出了耕地资源保护的政策建议,并在此基础上对桂平市耕地资源的改善进行了探讨.
The research made a quantitative analysis using RS＆GIS technology synthetically and abstracted five factor such as Slope, RVI , SQI, DVI, LUD as cultivated land quality assessment indicator. By Virtue of PSR framework, the evaluation index system of Guiping City was constructed, and the cultivated land was devided into five grades and corresponding land resource protection suggestions were put forward re-spectively and on this basis, the improvement of cultivated land resources in Guiping City was discussed.
