景观生态学在生态环境影响评价中的应用

Application of Landscape Ecology on Ecology Environment Impact Assessment

应用景观生态学方法,结合生态环境影响评价要求,从景观空间结构和稳定性两个方面对屏南县后垄溪一级水电站的景观生态做出评价。结果表明,项目建设对区域景观的空间结构影响主要表现在建筑物和水域两方面,项目建成后他们的优势度分别提高1%和0.9%,相对变化较小;项目建设中及建成后,区域内的人为干扰和景观破碎化程度增加,能量和物种的流动性下降,故应加强该方面的设计,以维持区域的生态系统稳定性。

Landscape ecology in Houlongxi first-step hydraulic power station in Pingnan county was assessea actopung the technique of landscape ecology, combining the assessment requirement of the ecology environment from the angle of special structure and stability of landscape. The results showed that the impacts on special structure of landscape from the proiect construction were buildings and water areas, the patch dominance of them were separately increased by 0.01 and 0. 009 after the completion of the project, but the change was relatively small. The degree of human-caused disturbance and landscape fragmentation was increased during and after the completion of the project, and the flow of energy and species both decreased, so the design of the part should be added that the stability of regional ecology ecosystem can be maintained.
