摘　　要：小型分散湿地发挥着多种生态系统服务功能,其科学、合理地保育利用对资源环境可持续发展有着重要意义。本文针对小型分散湿地数量多、分布广、利用频繁的特点,结合水资源管理业务需求,以统计区间内高频率水位的最大值作为生态水位,提出其可利用水资源量的快速计算方法;设计并实现基于WebGL水资源利用实况模拟的小型分散湿地水资源管理系统。以句容茅山地区为实验区,通过确定生态水位、构建湿地三维地形、计算定水位水量三个主要步骤,快速获得小型分散湿地的可利用水资源量,直观展示取用水的动态过程,以此应对小型分散湿地科学管理、可持续利用的社会需求,促进我国湿地水资源管理的系统化和规范化。Small scattered wetlands are numerous,widely distributed,and frequently used.They provide many ecosystem services and are essential to the sustainable development of resources and environment.In view of the requirements of water resources management,we proposed a fast calculation method of available water resources in small scattered wetlands.The method was based on the maximum value of high-frequency water levels in statistical intervals.We designed and implemented the method in a WebGL-based simulation and management system of water resource utilization for small scattered wetlands.The application of the system includes three main steps:(1)determination of ecological water level,(2)construction of a 3D wetland model,and(3)calculation of water quantity at fixed water levels.Taking the Maoshan region,Jurong City,as a case study,the proposed method can meet the requirements of scientific management and sustainable utilization of small scattered wetlands.It can also promote the systematization and standardization of wetland water resource management in China.
