摘要
通过建立一种在认知区域生态系统服务权衡协同关系的基础上,利用生态系统服务簇实现生态功能区划的方法,以针对生态功能区划提出差异性的管控策略,从而高效利用有限的生态资源,实现生态系统可持续发展。以浙江省嘉兴市为研究对象,(1)采用当量因子法测算了4种用地类型的11种生态系统服务价值;(2)采用相关性分析和冷热点分析探究研究区生态系统服务的权衡协同关系;(3)以K-means均值聚类算法识别生态系统服务簇,以其为依据进行生态功能区划,并提出各类生态功能区划管理建议。研究发现:(1)嘉兴市生态系统服务价值(Ecosystem Service Value,ESV)具备北部高,东南部次之,西南部低的空间分异特征;(2)除水资源供给服务与食物生产、原料生产、气体调节、维持养分循环服务呈现权衡关系外,嘉兴市大部分生态系统服务间呈现出显著的协同效应;(3)基于生态系统服务簇理论,嘉兴市生态系统服务簇可分为5种类型,相应划分为5种生态功能分区,并针对性地提出了管控措施。研究提出的方法能够较好识别区域生态功能,具有可行性和应用价值,并为探索协同多项生态系统服务,促进生态系统可持续发展的生态分区管控策略提供了新的思路。
Objectives:This paper hopes to establish a method for realizing ecological functional zoning using ecosystem service bundles based on the recognition of regional ecosystem service trade-offs and synergistic relationships,in order to propose differentiated control strategies for ecological functional zoning,so as to make efficient use of limited ecological resources and achieve the goal of sustainable ecosystem development.Methods:The study was conducted in Jiaxing City,Zhejiang Province,(1) the equivalent factor method was used to measure the value of 11 ecosystem services for four LULC;(2) correlation analysis and cold hotspot analysis were used to explore the trade-off & synergies of ecosystem services in the study area;(3) the K-means clustering algorithm was used to identify the ecosystem service clusters,based on which the ecological function zoning was carried out,and suggestions were made for the management of various ecological function zoning.Results:The study found that:(1) the Ecosystem Service Value in Jiaxing is high in the north,followed by the southeast and low in the southwest;(2) most of the ecosystem services in Jiaxing show significant synergistic effects,except for water supply services which show trade-offs with food production,raw material production,gas regulation and nutrient cycle maintenance services;(3) Based on the ecosystem services bundles theory,the ecosystem services bundles in Jiaxing can be divided into five types and correspondingly into five ecological function zones,and control measures are proposed in a targeted manner.Conclusion:The method proposed in this study can better identify regional ecological functions and has feasibility and application value,and provides new ideas for exploring ecological zoning control strategies that coordinate multiple ecosystem services and promote sustainable development of ecosystems.
