【摘要】 随着社会经济的发展和国家对水利建设的日益重视，许多上游本为天然流域情况的水库若干年后其上游发生了各种类型的人类活动，这些合理或不合理的人类活动改变了上游的天然状况，上游地质、地貌及水文情势变得复杂起来，一定程度上影响了水库所处流域的水文环境和水库的运行方式。若依然按照原有的调度规则进行调度，势必会对这一流域上下游的人民生活和城市建设等产生不利影响甚至是极大的危害、也会威胁水库本身的安全或者可能会浪费有效资源。上游修建多个中小水库就是一种较大规模的人类活动，本文研究旨在考虑上游多个中小水库影响的条件下，对现有的下游水库设计入库洪水过程进行调洪演算，定量分析上游中小水库的蓄泄对下游水库设计入库洪水过程调度的影响程度。本文主要从上游水库发生溃坝对下游水库设计洪水调度产生影响和上游水库有调蓄作用对下游水库设计洪水调度产生影响两个方面详细阐述了上游人类活动(多个中小水库的修建)对下游水库设计洪水调度的影响程度。论文以广东省长潭水库为研究对象，阐述了受人类活动影响的水库设计洪水调度研究方法，研究了水库在其上游修建了若干个中小水库以后，其设计洪水调度所受的影响程度，分析比较了研究结果，探讨了水库在考虑上游多个水库影响下的防洪标准、调度原则及水资源综合利用特点。更多还原

【Abstract】 With China’s socio-economic development and increasing attention to water resources projects’ construction paid by Chinese government, the upstream areas of many reservoirs which were originally natural catchments are currently intervened by different kinds of human activities. These rational and irrational human activities altered reservoirs’ catchments natural conditions, as a result, their geological, geographical and hydrological characteristics become more complicated, and consequently their greatly changed hydrological regimes affected reservoirs’ routine operation. If reservoirs are still operated according to the original regulating rules, this will cause negative impacts on, or even serious damage to, people’s lives and cities’ infrastructure, threaten the safety of reservoirs or waste effective resources. The construction of middle and small-size reservoirs is impact-profound human activities. This paper aims to conduct flood-routing of designed inflow floods of downstream reservoirs under consideration of existence of upstream middle and small-size reservoirs, quantitatively analyze the degree of impact of the upstream reservoirs’ dam-break floods or flood-regulating functions on design inflow floods of the downstream reservoirs. The paper selected Changtan reservoir in Guangdong province as case study site, investigated the impacts of 4 upstream reservoirs on Changtan reservoir’s design inflow floods and explored Changtan reservoir’s flood-protection standards, regulating rules and potential for integrated water resources utilization after newly-constructed upstream reservoirs being taken into account.更多还原
