基于GIS的城市水资源与生态需水量的研究

Study on urban water resources and ecological water requirement based on GIS

城市生态环境需水量主要是指城市中生态系统中自然系统的需水量,而地理信息系统(GIS)是对多种来源时空数据的综合处理分析和应用以及展示的平台。本文章在GIS软件环境下通过传统的水文分析计算与崭新的生态需水量计算方法相结合,对城市水资源与生态环境需水量的研究进行了初步探索。

The urban ecological water requirement mainly means the natural part of the system.The GIS is a platform to treatment and analyze the spatial-temporal data comprehensively and to show the information.This paper studies the urban water resources and ecological water requirement based on the method combining the traditional hydrological analysis and the new ecological water requirement calculation method.
