摘　　要：苏南水网地区景观格局日趋破碎化,生态保护与经济发展矛盾加剧,采用生态系统健康评价测度区域生态系统结构稳定性和服务功能可持续性,为区域空间管控策略的制定提供客观依据,增强水网地区生态系统自适应性。以苏州市的雪绿漾片区为例,基于“活力(V)-组织力(O)-恢复力(R)-贡献力(C)”生态系统健康评价模型,分析2002-2022年研究区生态系统健康时空分异特征,依据生态系统健康等级转移空间分布特征划定管控分区,并提出相应管控策略。研究结果表明:2002-2022年雪绿漾片区生态系统健康指数均值持续下降,由0.38下降至0.28,Ⅰ级和Ⅱ级健康空间占比减少了约13.72%,Ⅲ级健康空间占比下降了约4.66%,Ⅳ级和Ⅴ级健康空间占比上升了约18.38%;健康指数空间分布有一定差异,健康高值区多为水域密集地区,生态系统结构稳定、生态功能完善;健康低值区以高度城镇化区域为主,生态系统抗干扰能力较弱,生态健康整体水平较低。依据2002-2022年雪绿漾片区生态系统健康等级转移空间分布特征,将研究区划分为生态系统健康改善区、稳定区和退化区3类空间管控分区,并提出差异化的分区管控策略。生态系统健康评价可为空间分区管控提供科学依据,促进水网地区生态系统健康稳定及可持续发展。The landscape pattern of water network area in Southern Jiangsu is increasingly fragmented,and the contradiction between ecological protection and economic development is intensifying.With the proposed concept of ecological civilization construction and sustainable development strategy in China,the concept of ecosystem health is gradually paid attention to.A healthy ecosystem should have reasonable ecological structure and functional conditions.In this paper,Ecosystem Health Assessment was used to measure the stability of regional ecosystem structure and the sustainability of service functions,so as to provide an objective basis for the formulation of regional spatial management and control strategies,and enhance the adaptability of ecosystems in water network areas.Taking Xueluyang Area in Suzhou,Jiangsu Province as an example,this study analyzed the spatialtemporal differentiation characteristics of ecosystem health in Xueluyang Area from 2002 to 2022 based on the Ecosystem Health Assessment model of"Vigor(V)-Organization(O)-Resilience(R)-Contribution(C)"with reference to existing research results,determined the management and control zones according to the spatial distribution characteristics of ecosystem health grade transfer,and then put forward the corresponding control strategy.The results showed that:From 2002 to 2022,the mean value of ecosystem health index in Xueleuyang Area continued to decline from 0.38 to 0.28;the area of high-value area decreased,while that of lowvalue area increased significantly,which was potentially related to the continuous expansion of construction land and the gradual decline of ecological land area in Xueleuyang Area during the study period.The fragmentation of landscape structure and the increase of ecosystem fragility were related to each other.Specifically,the proportion of Grades I and II health space decreased by about 13.72%,that of Grade III health space decreased by about 4.66%,while that of Grades IV andⅤhealth space increased by about 18.38%.There were some differ
