- Eco-regionalization Based on Quantitative Method and Case Study

- 摘要:
- 该文在总结国内外有关生态分区研究的基础上，针对目前研究中存在的主观性强、专家选取对分区结果影响大的问题，在生态分区过程的两个关键点引入定量方法。应用主成分分析方法，确定各指标权重，筛选生态分区划分指标，确定各级生态分区的指标。应用系统聚类方法，确定各生态分区的最终边界。以辽河流域为例，选取降雨量、地势地貌、植被类型以及土壤类型等指标，应用定量化方法进行生态分区的划分，共划分一级生态分区3个，二级生态分区9个。该文旨在为生态分区的划分提供更为客观、科学的方法，从而为环境与资源的研究、评估、监测和管理提供适宜的空间分析框架，为生态管理和相关政策的制定与实施提供科学、合理的依据。
- Abstract:
- A literature review provided a thorough look at eco-regionlization.The analysis has shown that the primary methods used in eco-regionalization are qualitative,and the selection of experts has great influence on results.Therefore,quantitative method was needed.This paper explored quantitative methods to improve two major features of eco-regionalization.Principal component analysis was applied to the selection of relevant regional environmental factors,as well as hierarchical clustering method in boundary determination.The eco-regionalization of Liao River basin was taken as a case study.Four factors including rainfall,altitude,vegetation,and soil type were chosen for the delineation process.Three ecoregions of GradeⅠ,and nine ecoregions of GradeⅡwere delineated within Liao River basin.This paper was intended to provide an appropriate framework for environmental research,assessment,monitoring,and management using improved ecoregionlization method.
