- 摘要:
- 针对艾比湖流域生态环境灾害,分析其成灾原因及发生规律.从改变水量分配时间格局的角度,分析入湖水量季节调控的可行性并提出实施方案.具体为通过人工引、蓄水设施将秋、冬季入湖地表径流蓄积起来,在春季大风、沙尘多发季节注入湖中,减少此时沙尘天气的发生.确定春季所需补充的水量,先以湖区地形图为基础建立湖区数字高程矩阵,然后回归计算湖面面积与湖水体积对应函数,此时根据实测的当年春季湖面面积即可算出达到预定湖面面积所需水量.按照此方案修建人工引、蓄水设施并实施调控后,既可以治理流域沙尘天气,又可最大限度节省水资源.
- Abstract:
- The reason and rule of the Ebinur Lake valley enivironment and ecology disaster were studied.A new method was put forward to control lake volume based on water inflow control.The resavior in the valley is used to cumulate water inflows in autum and winter.In spring when gale comes,the water pours into the Ebinur Lake.The volume to be pour into lake in spring is calculated by a digital elevation matrix volume model.When this scheme is put into reality,the environment and ecology disaster in the valley can be controlled and the maximum volume of water can be saved.
