摘要

土地是人类赖以生存的根本。土壤侵蚀会导致土地资源的退化

造成环境恶化。农牧交错带是我国一个独特的地理景观

对它的研究在生态、区域发展上有重要意义。在定义土壤侵蚀指数的基础上

以土地资源类型为单元

以遥感与GIS为技术支撑

分析不同土地资源类型下土壤侵蚀类型与强度

阐明土地资源的土壤侵蚀背景

揭示出两者之间的关系

并作了区域上的分析。结果认为在我国农牧交错带的东部草地退化

西部沙化严重

亟需治理。

Abstract

Land resources are the foundation of human existence. Soil erosion results in land degeneration and environmental degradation

and influences weather change. In this study

land resource condition is quantified by defining a soil erosion index in an ecotone between agriculture and animal husbandry. Applying (remote) sensing(RS)and GIS

coverages of the agricultural area and the area used for animal husbandry are put into GRID(100 m pixel resolution) and overlain. The output data are analyzed to determine type and (intensity) of soil erosion. The soil erosion background of land resource is put forward and the relationship between soil erosion and the land resource is explored. Finally

a regional analysis is undertaken.
