当前,我们在注意抓好水库建设和管理运用,充分发挥工程效益的同时,绝不可忽视水库工程对环境的不利影响,因为这些不利因素往往制约着工程效益的发挥。作者就黑龙江省绥化地区17座大中型水库工程对环境不利影响的因素做了一下分析,初步提出了一些相应的减免措施。一、水文条件变化的不利影响有些水库如海伦市东方红水库和联丰水库的修建,改变了天然河道的水文特性,由于截留了河道的天然基流,往往造成水库下游河道断流,地下水位下
At present, we must pay attention to reservoir construction and management and utilization, give full play to project benefits at the same time, we must not ignore the negative impact of reservoir engineering on the environment, because these unfavorable factors often restrict the project efficiency. The author makes some analysis on the factors that adversely affect the environment of 17 large and medium-sized reservoirs in Suihua area, Heilongjiang Province, and puts forward some corresponding relief measures initially. First, the negative impact of changes in hydrological conditions Some reservoirs, such as the construction of Dongfanghong Reservoir and Lianfeng Reservoir in Helun City, have changed the hydrological characteristics of natural rivers. Due to the interception of the natural base flow of rivers, under
