生态系统服务功能重要性研究

Study on the Importance of Ecosystem Service Function

生态系统服务功能重要性的研究有助于确定生态保护的重要区域,可为生态功能定位以及生态环境的建设和保护提供重要的科学依据。本文首次将气候调节重要性作为生态系统服务功能重要性类别进行了研究,在以GIS与RS为基础的集成性技术体系的前提下,基于生态系统服务功能重要性综合评价多因子加权模型,构建了自然特性与功能价值因子相结合的两级层次结构的评价指标体系,并以山西省绛县为研究载体,对已建立的方法和技术进行了实证研究,研究结果与绛县的实际情况较吻合,从而验证了所建立方法的正确性和技术的可行性。

Studying on the importance of ecosystem service function helps to determine the important areas of eco- logical protection and provides important scientific basis for the location of regional ecological functions and the con struction and protection of ecological environment. This paper takes the importance of the climate regulation as a category of ecosystem service function for the first time and builds an index system of two-level structure,which is the combination of nature and value,under the premise of the integrated system based on GIS and RS and on the multifactorial weighting model of ecosystem service function. The paper takes Jiangxian County as an example to confirm the method. The research results match with the actual situation of Jiangxian County and verify the correct- ness and feasibility of the established method.
