排洪滩-
利用黄河1956~2004年实测资料，论证了表征健康黄河标志的低限流量、河道最大排洪能力、平滩流量、滩地横比降、水质类别、湿地规模、水生生物、供水能力等指示因子的阈值范围。
The hydrologic data from 1956 to 2004 are used to analyze the threshold of the relevant indexes including the minimum flow , maximum flood discharging capacity , bank-full discharge , water quality , wetland area , aquatic life and capacity of water supply .
