摘要
根据黄河河口生态系统的特征,基于鸟类栖息地和生物多样性保护、环境净化、地下水补充、盐水入侵防制以及蓄洪等因素,对其生态需水量进行了研究,并对防止海水入侵的淡水补给量、维持生物生长环境的淡水补给量、保持河口湿地合理水面面积及水深的淡水补给量、水循环消耗需水量和补给地下水需水量进行了分析计算.通过对上述5个方面需水量及其需水过程的耦合,得到黄河河口生态系统年平均需水量为78.21亿m3,最小月平均需水流量210m3/s(12月),最大月平均需水流量329 m3/s(6月).
Abstract
Based on the analysis of structure and function of Yellow River estuary, and its present ecological situation and water resources of Yellow River,the ecological protection objectives of Yellow River estuary were recognized as follows; providing the habitats for birds, biodiversity protection, improve the quality of the environment,underground water complementarity, preventing the seawater inbreak and storing up floodwater. Then according to the main ecological units of Yellow River estuary and their function requirements,the ecological water requirement are calculate with different methods the results show the ecological water requirement is 78. 21×108 m3 with minimum flow 210 m3/s (December) and maximum flow 329 m3/s (June).
