水生态系统服务供需视角下的水网乡村适应性规划策略--以吴江张鸭荡片区为例

Study on Rural Adaptability Planning Strategy of Water Network from the Perspective of Water Ecosystem Service Supply and Demand—A Case Study of Wujiang Zhangyadang Area

苏南乡村地区一直是中国乡村建设的先行区域,特殊的纵横交错的水网结构构成了一个错综复杂的系统,呈现出其他地区不具有的复杂性和生态特殊性。随着城镇的扩张,乡村的发展建设使其水网空间的平衡发展面临极大的挑战。传统单一静态的规划方法逐渐显示出无法适应经济、社会等发展要求的缺陷。苏南乡村地区以水为核心,从水生态系统服务供需关系的视角下探究水网乡村的适应性规划策略更加适应当前的乡村现状和需求。以传统水网乡村空间形态转译为基础,建立水生态系统供需服务评估体系,在评估水生态系统服务供需能力的基础上,分析供需分异模式及供需矛盾。从构建乡村水域空间生态格局、乡村水域空间功能分区规划,以及乡村水域空间多情景预判3个方面,提出苏南水网乡村的适应性规划策略,并为水网乡村的生态实践提出新思路。

Southern Jiangsu rural area has always been the first area of rural construction in China.The special crisscross water network structure constitutes a complex system,showing the complexity and ecological particularity that other areas do not have.With the expansion of cities and towns,the development and construction of villages make the balanced development of water network villages face great challenges.The traditional static planning method gradually shows that it cannot meet the needs of economic and social development.Taking water as the core of rural areas in southern Jiangsu Province,this paper explores the adaptive planning strategy of water network villages from the perspective of water ecosystem service supply and demand,which is more suitable for the current situation and demand of rural areas.Based on the translation of the traditional rural spatial form of water network,this paper establishes the evaluation system of water ecosystem supply and demand service,and analyzes the supply and demand differentiation mode and the contradiction between supply and demand on the basis of the evaluation of water ecosystem service supply and demand capacity.From the three aspects of optimizing the spatial distribution of imbalance between supply and demand,improving the self-adaptability of supply and demand balance,and strengthening the multi scenario control and management,this paper puts forward the adaptive planning strategies for the water network villages in southern Jiangsu,and puts forward new ideas for the ecological practice of the water network villages.
