塞罕坝国家森林公园泰丰湖景区生态需水研究

Ecological water demand of Taifeng Lake Scenic Area in Saihanba National Forest Park

以塞罕坝国家森林公园主要湖泊泰丰湖为研究对象,根据泰丰湖湖区监测点实际情况、湖泊面积、湖泊水位特征值,确定湖区最小生态水位,并计算出湖区最小生态需水量14.67万m^(3)/年;同时根据沟台子水文站、外沟门子蒸发站、大脑袋雨量站数据,对泰丰湖湖区进行水量平衡计算,根据分析结果,提出了维护湖区生态需求的建议。

Taking Taifeng Lake,the main lake in Saihanba National Forest Park,as the research object,based on the actual situation of monitoring points,lake area,and water level characteristics in the Taifeng Lake scenic area,the minimum ecological water level in the lake area is determined,and the minimum ecological water demand in the lake area is calculated to be 146700 m^(3)/year.At the same time,based on the data from the Goutaizi Hydrological Station,Waigouzi Evaporation Station,and Datou Rainfall Station,the water balance calculation of the Taifeng Lake area was carried out.Based on the analysis results,suggestions for maintaining the ecological needs of the lake area were proposed.
