摘　　要：生态系统服务供需分析可为区域生态规划提供客观依据。苏南水网乡村受城镇化影响目前面临水网生态功能衰退、生态斑块破碎等问题,以具有典型苏南水网乡村特征的苏州市澄湖西北片区为研究案例,运用当量因子法、土地开发指数定量评价生态系统供给与需求,并分析其生态系统服务供需关系。基于生态系统服务供需关系分异特征,从景观生态安全格局构建、生态功能分区管控规划、生态技术运用实施三个方面提出空间格局优化策略。The analysis of supply and demand for ecosystem services can provide an objective basis for regional ecological planning. Affected by urbanization, water network villages in southern Jiangsu are currently facing problems such as the decline of water network function and the fragmentation of ecological patches. Chenghu Northwest District in Suzhou was taken as a research case, which has typical rural characteristics of water network in southern Jiangsu. The supply value and demand of ecosystem services were quantitatively evaluated by using the equivalent factor method and land development index, and the supply-demand relationship of ecosystem services was analyzed. Based on the differentiation characteristics of supply and demand for ecosystem services, spatial pattern optimization strategies were put forward from three aspects:landscape ecological security pattern construction, ecological function partition management and control planning and ecological technology application and implementation.
