| 摘 要： | 从浙江省钱塘江流域现有的水资源开发利用中存在的生态环境问题出发,探讨了符合钱塘江流域生态环境特点的多年平均适宜生态环境需水内涵,并在此基础上,建立了河道内多年平均适宜生态环境需水和河道外多年平均适宜生态环境需水两个部分的计算模型.模型计算结果表明,钱塘江流域多年平均河道内生态环境需水量为1.59×10~(10)m~3/a,河道外生态环境需水量为6.70×10~9m~3/a,多年适宜生态环境需水总量为2.26×10~(10)m~3/a.研究结果可为浙江省钱塘江流域的生态环境保护、水资源的可持续利用以及湿润区生态环境需水研究提供决策依据.

| Abstract: | Based on the ecological and environmental problems caused by water resource exploitation in Qiantang River basin,the conception and connotation of annual suitable eco-environmental water requirements in Qiantang River Basin are analyzed. Correspo ndingly,a computation model is constructed to calculate both channel eco-environmental water requirement and riverside eco-environmental water requirement. Results show that the annual suitable eco-enviro nmental water requirements of channel and riverside are1.59×1010and 6.70×109m3/a,respectively. The total annual suitable eco-environmental water requirement amounts to2.26×1010m3/a.This research provides a scientific basis for eco-environmental protection,exploitation,and utilization of water resources not only in Qiantang River Basin but also in other similar humid basins. |
