摘　　要：提出利用VC++从底层开发溢油污染生物资源损害评估地理信息系统,用于实现对模型数据的有效管理和图形可视化.根据数值评估模型应用特点,建立评估模型数据库和地理信息数据库,给出了空间数据和属性数据的管理和查询实现方法.通过应用矢量和栅格空间数据模型、面向对象编程方法以及地图投影变换、图形绘制等图形显示技术实现空间数据的可视化.利用VC++对系统进行开发,除实现了一般GIS的基本功能外,还实现了潮流预报、溢油行为动态预测以及溢油事故海洋生物资源损害评估等专业应用功能.The development of a geographic information system （GIS） for marine oil spill biological resource damage assessment is proposed to provide effective data management and visualization for numerical assessment models. First, based on analyzing the features of the numerical assessment models, a numerical model database and geographic information database are built, and effective methods to manage and query spatial and attribute data are presented. Then, the visualization of spatial data is implemented by applying the vector and raster spatial data models, the object oriented programming methods, and the graphic display techniques such as map projection transformation and graphics drawing. At last, the system is developed using VC＋ ＋. In addition to the basic GIS functions, the system has functions of tidal current prediction, oil spill movement prediction and assessment of marine biological resource damage caused by spill accidents.
