尼尔基水库生态指标体系的构建

根据尼尔基水库建设的生态目标、水库建成后所面临的主要生态问题以及嫩江上游土地利用和土地覆被现状,将嫩江上游划分为6大生态功能区。针对各生态功能区所面临的主要生态问题,结合流域生态的战略目标,选取10大类生态指标构建尼尔基水库生态目标监测及评估的指标体系。分析结果表明,通过对这些指标的监测和评估,可为建设生态水库和改善嫩江下游生态环境质量提供科学依据。

Establishment of ecologic index system for Nierji Reservoir

Based on the ecologic objectives of the Nierji Reservoir, the main environmental problems and the status of land use and land cover upstream along the Nenjiang River after construction of the Nierji Reservoir are described. The study area along the Nenjiang River was divided into six ecologic function areas. In light of the main environmental problems of every ecologic sub-area, and the ecologic strategic objectives of the drainage basin, ten types of ecologic indexes were selected to establish the index system for monitoring and evaluating the ecologic objectives of the Nierji Reservoir. The analysis results indicated that monitoring and assessment of those indexes can provide a scientific basis for constructing an ecologically sound reservoir while improving the environmental quality of the study sub-area.
