中文摘要: |
针对南四湖的资料,构建了基于最低生态水位和最小湖区生态耗水的南四湖湖区最小生态需水计算模型。使用天然水位资料统计法、湖泊形态分析法和生物空间最小需求法计算了南四湖最低生态水位。3种计算结果相近。建议的上级湖最低生态水位为33.00m、下级湖为31.38m。基于频率95%的降水等资料,计算的湖区最小生态耗水为6.44亿m3/a。 |
英文摘要: |
Nansi Lake is the largest lake in the North China, located at the common boundary of Shandong Province and Jiangsu Province, including four lakes and is divided into upper part and lower part by a sluice weir. The model for calculating the minimum ecological water requirement of this lake is established based on the lowest ecological water level and minimum ecological water consumption according to the observation data. The lowest ecological water level is determined by means of statistical natural water level data, lake morphology analytic method and lowest space demand of biology method respectively. The results of these three methods are approximately the same. It is suggested that the suitable lowest ecological water level of the upper part of the lake is 330m, and the level of lower
part is 31.38m. The corresponding minimum ecological consumption is 0.644 billion m3/a. |
