辽宁双台子河口湿地生态环境需水量估算

Eco-environmental Water Demand of Shuangtaizi Estuarine Wetland

辽宁双台子河口湿地被列为《国际重要湿地保护区名录,》是世界上最大的芦苇沼泽湿地。基于生态学法并结合3S技术,以2000年为例计算双台子河口湿地最小、最适、最大的生态环境需水量,并对计算结果进行归类分析,得到各类型湿地的生态环境需水总量和单位面积需水量。可为双台子河口地区的水资源规划、生态保护、区域农业结构调整等提供科学依据,也可为其他地区河口湿地生态环境需水计算提供借鉴。

Shuangtaizi estuarine wetland has been listed as International Important Wetland Protectorate, and it is the world-wlde biggest moss land wetland. This article based on the ecological research method and the union remote sensing, 3 S technology, taking 2000 as example,calculated the minimum, most suitable and maximum eco-environmental water demand of Shuangtaizi estuarine wetland,then analyed the computed result, and gained total demand quantity and the unit area water demand. The study would be useful for the water resources plan, ecology protection, regioned agriculture structure adjustment of Shuangtaizi area. And it would also provide a scientific basis, for other estuarine wetlands＇ eco-environmental water demand calculation.
