中文摘要：

以图们江流域近20年的水文数据为基础,利用统计分析方法、水文学方法、GIS和遥感技术,对其主要支流布尔哈通河、嘎呀河、珲春河的生态环境需水量进行了量化研究.结果表明：各支流的河道径流可充分满足河道内生态环境需水量的要求;嘎呀河河道外生态环境缺水3.3亿m3,布尔哈通河、珲春河河道外生态环境需水分别占各自水资源总量的79%,71%,目前表现为不缺水.

英文摘要：

This paper is mainly based on nearly two decades hydrological data of Tumen River Basin,using statistical analysis,hydrology methods,GIS and remote sensing technology to have environmental water demand quantitative research for its main tributaries—Buerhatong river,Gaya river,Hunchun river.Research results show that：（1）the river runoff of tributary could meet in-stream ecological water demand.（2）the stream ecological environment of Gaya river is a certain degree of water scarcity,Buerhatong river,Hunchun river in the aggregate performance of not dry.
