盈江国家湿地公园生态需水量研究

Study on the Ecological Water Demand of Yinjiang National Wetland Park

根据盈江国家湿地公园的生态系统特性,利用大盈江坝区的实测地形图、拉贺练水文站的实测水文资料,通过建立湿地生态需水量模型,计算了盈江国家湿地公园生态需水量,枯期最小生态需水量20.9 m3/s;汛期最小生态需水量47.2 m3/s,大盈江上游来水大于生态最小需水量,盈江国家湿地公园的生态需水量是有保障的。

This paper established ecological water demand model of wetland and calculated ecological water demand of Yinjiang national wetland park,which was based on attributes of ecosystems for Yinjiang national wetland park,topographic map and measured hydrographic data at Lahelian hydrometric station.Results show that the minimum ecological water requirement is 20.9 m3/s and 47.2 m3/s in dry season and flood season respectively.The upland water is much greater than the minimum ecological water demand from Dayingjiang river.The wetland ecosystems are healthy for Yinjiang national wetland park.
