摘要

流域水量平衡分析是水资源现状评价与水资源合理调度研究工作中的一个核心。本文基于遥感技术估算的蒸散

结合监测统计数据

提出了流域耗水平衡方法

以海河流域为例进行了2002年—2007年流域及子流域的耗水平衡分析

流域多年平均蓄变量为-62.3亿m3

其中农业生产是流域水资源消耗的主要因素

占耗水总量的54.3%

年际变动范围较小（-5%—8%）。通过流域蓄变量变化和流域蒸散结构的分析

揭示海河流域存在的水资源问题

为流域水资源管理和节水型社会建设耗水控制和节水方案提出建议。

Abstract

The basin level water balance analysis is the core of water resource evaluation and rational management.A method of basin level water consumption balance is presented in this paper

based on evapotranspiration estimated by remote sensing and combining statistic data.In a case study

we analyzed the water consumption balance in the Hai Basin from 2002 to 2007 and found the average water storage change to be-6.23 billion cubic meters.The agriculture sector is one of the biggest consumers of water resources

accounting for 54.3% of the total water consumption

although the inter-annual change ranges are lower（-5% to 8%）.The water resource problems are discussed in this paper based on the analysis of changes in water storage and the evapotranspiration structure

and some suggestions for region water source management and water-saving society construction are proposed.
