GIS和RS在水土保持规划中的应用

本文在传统水土保持治理研究的基础上,探索应用GIS和RS技术对现有地图和卫星影像图的图像解译分析,提取影响水土流失的各类因子基础信息,建立图形和空间属性数据库,模拟研究区的水土流失地学模型,用数值定量反映土壤侵蚀强度及其空间分布,并利用其强大的空间分析功能,重新整合规划研究区的土地资源,为政府决策提供科学的理论依据.

The Application of Soil and Water Conservation Planning Based on GIS and RS

Based on the traditional research of soil and water conservation, this paper explores the interpretation and analysis of the present map and Landsat TM on the basis of GIS and RS. It analyzes all the possible factors which might affect soil and water conservation by establishing the region of figure and spatial database and making a numerical of the strength of soil erosion and its spatial distribution with the method of data analysis according to the simulated soil and water conservation. It also reforms and reprograms the soil resource utilization by means of the powerful spatial analysis of GIS and RS. This way provides the scientific theoretical basis for the government determination and policy.
