摘  要：
该文在遥感和GIS技术支持下,以长时间序列(1996～2006年)的多源SPOT高分辨率影像为主要数据源,在准确获取土地利用变化信息的基础上,利用土壤资源质量指数(SQI)来评价和分析杭州市快速城市化过程中土壤资源质量损失状况。结果表明:10a间,杭州市快速城市化过程中土壤质量付出的代价是巨大的,城市扩张侵占的都是优质土壤,其中优质黄松土的损失面积占到损失总量的38.11%。土壤资源质量等级最高(Ⅰ)的土壤资源的损失量占到了总量的43%。其中耕地发生质量损失的面积占到损失总量的83.83%,这其中45.86%的损失量都来自土壤资源质量等级最高的耕地资源。城市化过程中土壤资源有效利用与合理保护已成为亟待解决的问题。

摘  要：
Based on remote sensing and GIS techniques,a long time series(1996-2006)of multi-source SPOT high spatial-resolution images was applied to extract accurately land use change information.Based on the information,soil resource quality index(SQI)was applied to assess and analyze the losses of soil quality in the rapid urbanization process of Hangzhou city.The results showed that Handzhou's rapid urbanization process was at the cost of the serious losses of soil quality during the decade.In particular most of urban expansion took place in the high-quality soil area with the lost areas of fluvio-marine yellow loamy soil occupying 38.11%of the total losses.Of total losses,the lost areas of soil resource with the best degree of SQI occupied 43%,and the lost areas of farmland quality occupied 83.83%,with 45.86%farmland resource lost areas belonging to the best degree of SQI.The effective utilization and reasonable protection of soil resource during urban development has become a urgent problem to be solved.
