基于GIS的土壤侵蚀与土地利用关系研究

以福建省延平区为例，在地理信息系统软件ＡＲＣ／ＩＮＦＯ的支持下探讨土壤侵蚀与土地利用的关系。研究结果表明，不同土地利用类型的土壤侵蚀程度差异显著，各种土地利用类型土壤侵蚀率的顺序为：园地〉耕地〉林地〉草地，尤其是林地中的疏林地、园地中的茶园和耕地中的旱地土壤侵蚀程度尤为严重。文中还提出土地利用与水土保持相结合的具体对策，以实现土地资源可持续利用的目标。

Study on the Relationship between Soil Erosion and Land Use Based on GIS

Taking Yanping district as a case, the spatial information database about soil erosion and land use have been established based on ARC/INFO software of geographic information system. The relationship between soil erosion and land use has been researched. The results indicated that the soil erosion degrees of various land use types are quite different. The erosion ratio of different land use types showed the following order: fruit and tea garden>cultivated land >forest land >glass land .The soil erosion degrees of sparse forest, tea garden and dry field are more serious than that of other land use types. The suggestions about combination of land utilization and soil conservation are put forward.
