摘要
分析了现行水库调度方法的不足,指出应在实现社会经济多种目标的前提下,兼顾河流生态系统需求,实行水库的多目标生态调度。文中讨论了水库多目标生态调度的方法,包括建立相应法规体系;保证维持下游河道基本生态功能的需水量;模拟自然水文情势的水库泄流方式;进行水库泥沙调控及水库富营养化控制;减轻水体温度分层影响;进行防污调度以及增强水系连通性等方面的调度技术。
This paper analyzes the limitations of the measures taken in current reservoir operations and points out that multi-objective ecological operation of reservoirs should be carried out in order to meet the needs of river ecosystems while implementing various socioeconomic objectives. The paper discusses the methods of multi-objective ecological operation of reservoirs, which covers the establishment of legislation systems ; water demands for the basic ecological functions of downstream river channel; reservoir discharge patterns simulating natural hydrological regimes ; regulation and control of sedimentation and eutrophication of reservoirs; mitigation of the influences by water temperature stratification; the operation techniques in pollution prevention and connectivity reinforcement of water systems.
