从模型到应用:基于生态系统服务权衡的乡村生态修复规划工具研究

Model to Application:A Study on a Decision Support Tool for Rural Ecological Restoration Planning Based on Ecosystem Services Trade-offs

在全球范围内的气候变化背景下,具有多种功能和服务价值的乡村生态空间成为当下国际生态规划研究与合作的关注热点之一。为实现乡村生态空间的精准管理与规划,中德双方围绕联合课题“生态系统服务概念在德国鲁尔与中国大都市区韧性发展模式下的绿色基础设施规划应用”进行了深入探索。在土地利用与土地覆盖类型的基础上,进一步识别了生物群落类型,并基于调节、供给、文化三大生态系统服务类型,选取了评估生态系统服务供需权衡的指标和对应权重,构建了乡村生态空间规划场景下的生态系统服务价值评测模型。以上海市水库村为例,运用该课题的评测模型,初步评估了典型乡村生态规划场景下的生态系统服务价值。最后,从应用尺度、研究范围以及操作流程三个方面总结了该评测模型的优化方向。

In the context of global climate change,rural ecological spaces,which offer a variety of functions and service values,have emerged as one of the focal points in international ecological planning research and cooperation.To achieve precise manage-ment and planning in these rural ecological spaces,the Sino-German joint project"Implementation of the Ecosystem Services Concept in Green Infrastructure Planning to Strengthen the Resilience of the Metropole Ruhr and Chinese Megacities"under-took an in-depth exploration.This project,based on land use and land cover types,further identified biotop types.Utilizing three major ecosystem service types:regulating,provisioning,and cultural,it selected indicators and corresponding weights for assessing ecosystem services trade-offs between supply and demand,thereby constructing a model for evaluating ecosystem service values in rural ecological space planning scenarios.Taking the Shuiku Village in Shanghai as a case study,this paper uses the evaluation model and preliminarily assesses the ecosystem service values in typical rural ecological planning scenarios.Finally,this paper summarizes the optimization directions of this evaluation model in terms of application scale,research scope,and operational procedures.
