摘  要:
东江湖是湖南省蓄积量最大的一级饮用水湖泊,是国家4A级风景旅游区,旅游资源以山水、湿地、自然景观为主。为保护好东江湖湿地,研究基于数字高程模型(DEM)和地理信息系统(GIS)技术,对整个资兴市东江湖流域进行了水文模拟分析,提取了水流方向、汇流量、流程、流网、流域界线、流域面积等水文特征。运用ArcGIS进行东江湖子流域的划分,最终生成了东江湖数字流域,为东江湖景观生态环境方面的研究提供了数据平台。

摘  要:
Dongjiang lake is the first level drinking water with the largest water storage in Hunan province,is listed as the National 4A level scenic area.Its tourism resources are mainly composed of land scape,wetlands and natural landscape.To preserve the wetlands in Dongjiang lake,this thesis gave out a hydrological simulation analysis of the whole lake basin in Zixing city based on the technology of DEM and GIS.It had extracted such hydrological features as the flow direction,flow amount,flow path,flow net and drainage basin.With the ArcGIS,the sub basins of Dongjiang lake were divided,eventually contributing to the digital basins of Dongjiang lake.Thus a data platform for the research on environment around Dongjiang lake was provided.
