【摘要】：为保护北方地区湿地生态环境健康、恢复物种多样性,首要任务是确定湿地的生态需水量,以确定所需补水量。针对北方地区的河道型湿地,以济南市玉符河湿地为例,考虑丰、平、枯水年不同降水频率下的水面净蒸发,结合植被、土壤、野生生物栖息地、地下水补给需水量,利用水量平衡法汇总得到针对不同生态目标的理想、适宜和最小生态需水量。计算结果表明:消耗型最低生态目标的理想、适宜、最小生态需水量分别为5.976×10~6~7.018×10~6m~3、3.954~4.857×10~6m~3、1.937×10~6~2.837×10~6m~3;保护型合理生态目标的理想、适宜、最小生态需水量分别为9.839×10~6~11.181×10~6m~3、5.817×10~6~6.922×10~6m~3、2.762×10~6~3.770×10~6m~3。计算成果为下一步玉符河湿地生态环境健康的保护和物种多样性的恢复提供了理论支撑。
[Abstract]:In order to protect the ecological environment health and restore species diversity, the most important task is to determine the ecological water requirement of the wetland and determine the amount of water needed. In view of the river type wetland in North China, taking the Yufu River wetland in Jinan as an example, considering the net evaporation of water surface under different precipitation frequency in abundant, flat and dry water year, combining vegetation, soil, wildlife habitat, groundwater recharge water demand, The ideal, suitable and minimum ecological water requirements for different ecological objectives were obtained by using water balance method. The results show that the minimum ecological water requirement of the consumptive type is ideal and suitable, and the minimum ecological water requirement is 5.976 脳 107.018 脳 106.018 脳 10 ~ (6) m ~ (3) ~ (3) ~ 3.954 ~ 4.857 脳 10 ~ (6) m ~ (31.937 脳 10 ~ (6) 脳 10 ~ (-6) m ~ (3), and the ideal and suitable minimum ecological water requirement of the conservation type is 9.839 脳 10 ~ (10) ~ (6) ~ (11.181) 脳 10 ~ (6) ~ (-1) ~ (36.922 脳 10 ~ (6) ~ (3) ~ (3) ~ (3.762 脳 10 ~ (6) 脳 10 ~ (10) m ~ (3) ~ (3). The results provide theoretical support for the protection of ecological environment health and the restoration of species diversity in Yufu River wetland.
