山东半岛东部湿地生态系统服务评价及比较研究

Evaluation and Comparative Study of Ecosystem Services of Wetlands in Eastern Part of Shandong Peninsula

以山东半岛东部的烟台市和威海市为例,利用层次分析和主成分分析方法对研究区各县市湿地服务进行评价,采用自然间断法的方式将各市县湿地生态系统服务等级进行划分。结果表明:两种方法的评价原理和结果虽有差异,但都将烟台市辖区、威海市辖区划分为高生态服务地区,将栖霞市和招远市划分为低生态服务区。上述两种方法虽然评价原理不一致,但通过互相验证,更能真实地反映研究区湿地生态系统服务状态。

Yantai and Weihai located in the eastern part of Shandong Peninsula were taken as an example, AHP method and principal component analysis method were used to evaluate wetland ecosystem services in the study area, and natural discontinuity method was used to grade the wetland ecosystem services. Although the two evaluation methods were different in evaluation principles and results, the two cities of Yantai and Weihai were graded into high value of ecological service, and the cities of Qixia and Zhaoyuan were graded into low value of ecological services. This indicates that though these two methods are not consistent, they can more realistically reflect the status of wetland ecosystem services in the study area by veriifcation with each other.
