| 摘要: |
| 对扎龙湿地生态系统需水量计算方法进行了研究,提出了适宜生态环境需水量和最小生态环境需水量计算方法; 对扎龙湿地湖泊水库、明水沼泽和芦苇沼泽面积上的生态环境需水量、扎龙湿地适宜生态环境需水量及最小生态环境需水量进行了计算和分析:1986-2002年扎龙自然保护区生态环境需水量的变化范围为5.22×108m3-5.92×108m3;扎龙湿地自然保护区的适宜生态环境需水量为5.55×108m3、保证率为75%的最小生态环境需水量为2.89×108m3,保证率为95%的最小生态环境需水量3.54×108m3. |

| Abstract: |
| The method for calculating the eco-environmental water requirement in the Zhalong Wetland are studied,and the methods for calculating the appropriate quantity of the eco-environmental water requirement and calculating the minimum quantity of the eco-environmental water requirement are put forward. The eco-environmental water requirement in all kinds of the land use area in the Zhalong wetland including the lake, in the swampland saturating with water and in the swampland covering with bulrush, the appropriate quantity of the eco-environmental water requirement and the minimum quantity of the eco-environmental water requirement are calculated and analyzed. It is concluded that, the quantity of the eco-environmental water requirement in the whole Zhalong Wetland varies from 522 millions m3。592 millions m3 during from 1986 to 2002, the appropriate quantity of the eco-environmental water requirement is 555 millions m3, the minimum quantity of the eco-environmental water requirement with the ascuring probability of 75% is 289 millions m3 and the minimum quantity of the eco-environmental water requirement with the assuring probability of 95% is 354 millions m3. |
