Ecological zone Evaluated in Natural Reserve by GIS

摘要

As a special area of nature ecosystem, Nature Reserve is the core area to protect biodiversity, and an important part of government environment policy. Taking Beijing Labagoumen Nature Reserve as studying area, supported by multi-data resource as Digital Elevation Model and geo-spatial data, also spatial analyst technology including GIS and RS, which make expert knowledge related to spatial raster to express spatial raster's importance according its eco-attribute to make eco-evaluation index raster or layer, three and four level of eco-evaluation in this nature reserve was got through multi-layer raster map algebra operation based on multi-factor weighted model by using spatial analyst module of ArcGis9.x released by ESRI. It shows a balance to protect and develop resource in Nature Reserve.
