| 摘 要： | 深入研究土地利用和土壤侵蚀关系对认识人类活动在自然环境变化中的作用机制具有重要意义。以TM影像为数据源,基于ERDAS遥感处理平台和ArcGIS地理信息系统平台,综合分析了费县1987年和2007年两个典型时期的土地利用、土壤侵蚀的时空变化。结果表明：费县土壤侵蚀主要发生在耕地、林地、草地这3种土地利用类型中;1987-2007年20a间,费县耕地、草地、水域和未利用土地面积减少,林地、建设用地面积增加,土壤侵蚀面积减少,侵蚀等级下降。总体来说,费县土地利用和土壤侵蚀状况都是向良性的轨道发展。建议今后在继续进行退耕还林的同时,推行合理的耕作制度,有效减少土壤侵蚀。

| Abstract: | Studying the relationship between landuse and soil erosion is important for the understanding of human activity on the mechanism of natural environment change.The relation between landuse change and soil erosion change was explored using the data from TM images in the two periods of 1987 and 2007 on the platform of ERDAS and ArcGIS.Results showed that soil erosion mainly occurred in cultivated land,forest land and grass land.The areas of cultivated land,grass land,water and unused land decreased,the areas o... |
