摘　　要：为及时、准确地获取大范围环境影响因子,避免商业软件平台昂贵的价格和难以扩展的开发环境,结合地理信息系统和遥感技术进行生态环境要素遥感定量反演平台构建。以MapWindow作为底层框架,对其Dotspatial组件库的功能模块进行抽取和修改,完成平台的系统设计以及各功能模块的实现。其中,反演算法经过封装编译处理生成动态链接库,然后在平台中对动态链接库进行调用,最终以插件的形式将反演功能模块加载至平台。平台实现了遥感数据的气溶胶光学厚度、悬浮泥沙浓度、叶绿素浓度反演和显示等功能,可为环境管理部门提供大范围、快速的决策支持,具有较好的可扩展性。In order to obtain large-scale environmental factors timely and accurately, and to reduce the high cost of buying commercial software and to improve the extensbility of the platform, this paper constructs a platform for quantitative retrieval of eco-environmental factors by integrating geographic information system and remote sensing. This platform uses MapWindow as its underlying framework, extracts and modifies the functional modules of Dotspatial component library in MapWindow. We design the architecture of the system is designed and various functional modules have been developed. It is noticed that retrieval algorithm has been encapsulated to generate the dynamic link library (DLL), which is can be called in the platform, and works as plug-ins when loading retrieval function modules. The platform has functions such as retrieval and display of aerosol optical depth, suspended sediment concentration, and chlorophyll-a. It can provide large-scale and quick decision-making supports for environmental management departments. Besides, the system is of good scalability.
