摘要
区域开发的生态累积效应是人类活动对生态系统的影响在一定时间和空间上积累,达到一定阈值后所造成的生态环境变化,表现在景观格局、生态系统结构和功能、气候特征、土壤特征、生物群落特征与生物多样性、水土资源特征等方面。该研究目前主要集中在其变化过程监测研究、评价研究、方法论研究以及机理与协同效应研究方面;重大水利工程建设影响区域、人工绿洲区、湿地区为该研究的热点区域。区域开发的生态累积效应研究是较大范围开发活动生态环境后评价工作的基础,也将为今后开展生态文明建设单元筛选和规划提供支撑。
The ecological cumulative impact occurred in development of region is the environmental changes caused by the accumulation that human activities influence on ecosystem in a certain time or space when it reaches threshold value. It has an expression in many ways such as the pattern of landscape, the structure and function of ecosystem, the characters of climate, soil, biology community and biodiversity, the characters of water and soil resources etc. At present, this research mainly focuses on the survey research, evaluative research, methodological research, mechanism and synergistic effect in change processes of ecological cumulative impact. The areas such as the area influenced by a large scale of water conservancy project, manpower oasis area, wetland area are hotspot areas for this research. The research of ecological cumulative impact occurred in development of region is base of evaluative work for the environment after a large range of developing activities and it will be a support to us on the filtration and planning of units in developing of ecological civilization.
