摘要
针对新疆喀什地区开展环境资源监测和变化研究的需求,基于ArcEngine组件和丰富的功能类,通过有序的空间分析操作组合,.afr格式的"虚拟栅格"作为影像波段运算的良好媒介,结合多线程并发技术,构建了一个订单式快速简单实现环境资源动态监测与评估的系统.对系统的总体设计和核心功能设计作了重点介绍,包括任务管理,水体、植被、冰雪信息提取,动态监测与评估,和专题图出图等功能,并给出了系统的应用实例.该系统符合环境资源动态监测与评估的业务化应用要求,可及时宏观地监测区域的环境资源变化发展情况,服务于区域经济建设需要,可以广泛应用于环境资源监测领域,具有一定的通用性和扩展性.
Aiming at the demand for monitoring and change research on environment and resources in Kashgar of Xinjiang province, a rapid order-style dynamic monitoring ahd evaluation system on environment and resources was constructed. Based on ArcEngine components and rich functional classes, the system was built upon the combinations of orderly spatial analysis operations, ＂virtual raster＂ in .afr format as a decent medium for band operations on remote sensing images, and multithreading technology. The architecture of the system and its core functions were exhaustively introduced, including task management, information extraction on water bodies, vegetation and ice, dynamic monitoring and evaluation, and thematic map production. Furthermore, the system application examples were presented. Meeting the requirements on operational applications, the system provided a good way to timely monitor changes and developments on environment and resources in a region, thus contributing to the regional economic development. The system can be widely used in the field of monitoring on environmental factors and resources, which displayed certain versatility and scalability.
