摘要
生态环境需水研究的重要价值之一在于为实际生态环境补水提供依据,而河道内生态环境补水则更引人关注。与生态环境需水类似,河道内生态补水也存在兼容问题,需要进行整合计算。将河道内生态环境补水整合计算分为两个部分,其一是横向类型生态系统之间,其二存在于纵向河道上下游之间。根据水的流动性原理和水量平衡方法提出了河道内生态环境补水整合计算方法,将其应用于海滦河流域北四河下游地区,结果表明该地区多年平均状况下河道内生态环境补水量约为10亿m3,从而为流域机构对生态环境进行有效合理地补水提供了重要支持。
The value of researching for ecological and environmental water requirement is to rest on practical ecological and environmental water supplement, which focuses on the field about instream. Meanwhile, the problem of conformity of ecological and environmental water supplement exists in the research, therefore it is necessary to carry out conformity calculation. The problem is divided into two parts： one lies in the different ecosystem, and the other about between the upper and lower part of a river. According to the principle of water mobility and water balance, the methods of in-river ecological and environmental water supplement conformity calculation is provided. After applying in the region of lower part of the North Four rivers which belong to Haihe River basin, it can draw a conclusion that the total ecological and environmental water supplement is about 1 billion ms on the average condition, which provides important support for the administration to supply with ecological and environmental water effectively and reasonably.
