多沙粗沙区生态区划指标体系研究

Study on Indices of Ecological Regionalization in Coarse and Multi-sediment Area

人口、资源、环境与发展影响生态系统的功能,充分认识生态系统的动态行为是确立生态区划指标的关键。在详细分析多沙粗沙区生态环境特征的基础上,综合应用层次分析法(AHP)和专家打分法(Delphi)建立了该区域生态区划的指标体系,为多沙粗沙区生态区划提供了定量的依据。

Ecological system is affected by population, resource, environment and development. First of all, studying the dynamic change of ecological system is the foundation of ecological function regionalization. On the basis of analyzing the character of the ecological environment, and by using AHP（Analytical Hierarchy Process） with Delphi, the indices of the ecological function regionalization in coarse and multi-sediment area are put forward finally, to provide the basis for the ecological regionalization.
