摘　　要：图像自动识别系统可提取原始图件中栅格数据的属性元素并生成矢量数据。本文选取北川县系列基础图件,运用图像自动识别系统将其转换成矢量数据;在GIS技术的支持下,对矢量图层进行耦合叠加和分析。在此基础上,综合考虑自然因素与人类活动的影响,形成了北川县生态功能区划方案,将北川县划分为3个生态区和11个生态功能区,并提出各生态区的产业发展方向,为实现区域社会经济与生态环境的可持续协调发展提供有益的参考。Image auto-recognition system is a processing platform for extracting the grid data of characteristic element from original map and converting grid data to vector data. A series of maps were selected, which were processed and analyzed by the support of images auto-recognition system and GIS technique. Base on the results, considering of the impact from natural factors and human activities, three ecotopes and eleven eco-functional zones were subdivided. Then the industrial development direction of each ecotope were put forward. All of this can provide a reference to realize the sustainable development in both social economy and ecological environment.
