Paper Abstract

GIS based Soil and Water Conservation Aided Planning and Design (SWCAPD) is a crucial component for soil and water conservation monitoring and information management system, which provides decision support for small watershed soil and water conservation. GIS affords effective method to manage a large amount of spatial and attribute information about a small watershed, meanwhile, it is significant to discover potential topographical information using GIS spatial analysis. Topographical information includes elevation, slope and aspect and so on, which provides proofs for planning measures. Land use patches layer is regard as the basic cell for planning and design, and the accuracy of patches layer topographical information directly influences the planning result. On the basis of paper relief maps, DEM is obtained after a series of data processing, and it will be clipped by land use patches layer. Finally patch topographical information is acquired and stored. Aided decisions for planning measures are made after combining the acquired topographical information to expert rules and foundation data. The function framework of SWCAPD is given in this paper, and it is implemented aiming to a certain small watershed.
