森林水文效益卫星遥感研究

Forest Hydrological Effect Assessment via Satellite Remote Sensing Techniques

应用卫星遥感技术结合地面样地调查和流域多年水文资料分析的方法，对长江上游４个典型流域森林水文效益进行研究与评价，弄清各流域下垫面要素的性质和结构、流域水文参数变化规律，以及流域森林水源涵养林的涵水机理和评价方法，提出长江上游水源林的经营措施，为“九·五”长防林建设研究提供参考资料。

his paper discussed the methodology and the procedures for assessment of forest hydrological effects in four typical trial areas of the upper reach of Yangtze River by means of satellite remote sensing techniques combining with sample ground survey and historical hydrological data.The researches also aim at the clarification of the properties and structure of underlying surface factors and the change of hydrologial parameters,the principles of water conservation and the assessment methodology of conservation forest as well.The management measures are also discussed,which provide a fundamental references for the conservation forest construction programme of Yangtze River in the National Ninth Five-Year Plan Period.
