摘要
地理信息系统（GeographicInformationSystem，简称GIS）以其独特的功能在各个领域中应用广泛。本文针对目前水资源评价中普遍存在的问题，论述了应用GIS软件之-Ar-cview的空间分析功能和等值线的生成，通过生成区域降水等值线和径流等值线来计算区域降水量和地表径流量及其统计特征参数，为区域水资源量的计算提供新的方法。
Geographic Information System(GIS) gets more attention in many fields by its special function. In this paper, common problems in regional water resources assessment models are discussed at first. Then, one of GIS softwares,Arcview, has been introduced especially for its spatial analysis and contour generation. Regional precipitation, runoff and their statistic parameters are created by the contour of precipitation and surface runoff. All of these new methods are applied to the calculation of regional water resources.
