大洋河流域河口湿地生态环境评价三维系统的设计与实现 Design and Implementation of Three-Dimensional System for Estuarine Wetland Ecological Environment Assessment in Dayang River Basin

Abstract

以Skyline为三维GIS平台，借助SuperMap、3DMAX等软件，在C#环境中开发了大洋河流域河口生态环境评价三维可视化系统。该系统实现了对流域河口区的基础地理信息数据、遥感数据、外业调查数据及文本资料数据的整合管理，建立了大洋河流域河口的三维场景。并基于河口湿地景观格局指数、生境质量指数，河口区环境要素反演方法，从流域陆源风险、河口湿地生态健康、河口流域生态安全三个方面对大洋河流域河口的生态环境评价方法和模型集成进行了分析，并对成果进行二三维一体化展现。 Three-dimensional visualization system of estuarine eco-environment system evaluation in Dayang River Basin was developed in the C# environment with Skyline as the 3D GIS platform and SuperMap and 3DMAX softwares. The system realizes the integrated management of basic geo-graphic information data, remote sensing data, field investigation data and text data of the water-shed estuary area, and establishes the 3D scene of estuaries in the Dayang River Basin. Based on the estuarine wetland landscape pattern index, habitat quality index and estuarine environmental factors inversion method, the eco-environmental evaluation methods and model integration of Dayang River Basin were analyzed from three aspects: land-basin risk, the ecological health of es-tuary wetland and the ecological security of estuarine watershed. Finally, the system displays the results in 2D and 3D platform.
