摘要
以辽河干流流域为例,综合运用InVEST模型、K-means聚类、最小阻力模型等方法,基于流域重要生态系统服务的供需关系、空间流动关系以及生态安全格局关键点,构建“问题导向—量化评估—分区管控—工程布设”的生态修复规划技术路线。在对生境质量、产水量、水质净化和土壤保持4项核心生态系统服务供需进行量化分析的基础上,一方面采用生态系统服务的供需簇分类方式实现生态修复分区,对流域采取分类分区管控策略;另一方面,通过构建生态安全格局,精准识别生态修复关键区,并进行重点工程布设。研究成果不仅可以为辽河干流流域的生态修复提供依据,其构建的生态修复规划逻辑框架还可以为大中尺度流域的生态修复工作提供参考。
With Liao River Mainstream Watershed as an example,the methods of InVEST model,K-means clustering,and minimum resistance model are comprehensively used to establish a technical path of ecological restoration planning following the framework of"problem orientation-quantitative evaluation-zoning governance-project arrangement".This path is based on the demand-supply relationship,space flow relationship of important ecosystem service within the watershed,and key points of the ecological security pattern.A quantitative analysis is conducted on the supply and demand of four core ecosystem services:habitat quality,water yield,water purification,and soil conservation.On one hand,ecological restoration zoning is achieved through the method of supply-demand cluster classification of ecosystem services,and a classified and zonal management strategy is adopted for the watershed.On the other hand,key areas for ecological restoration are accurately identified,and project arrangements are made by constructing an ecological security pattern.Not only can the study results provide strategies for the ecological restoration of Liao River Mainstream Watershed,but the ecological restoration planning logical framework can also offer important references for ecological restoration work in large and medium scale watersheds.
