摘要
以上年度小班数据和现势的遥感影像为主要信息源,从年度监测角度出发,综合运用RS、GIS技术、数据库技术、专家知识库、林分生长模型等技术,充分对各种时空信息进行数据挖掘,通过深入分析和二次开发,设计并开发了广东省森林资源年度监测信息系统。该系统除了具有基本的森林资源信息管理功能之外,最大的优点是实现了空间数据自动更新、部分属性数据的智能监测,为林业管理部门进行森林资源动态监测提供了高效的操作平台,促进了森林资源年度监测的智能化、自动化。该系统对提高我国基层林业部门的森林经营管理水平具有重要意义。
Based on current remote sensing image and subcompartment data of last year, from the angle of annual monitoring, using RS, GIS, database technology, expert knowledge base and stand growth model syntheti- cally, combined with data mining technique on all kinds of spatio-temporal information, through in-depth analysis and secondary development, annual forest resources monitoring information system was developed. Besides basic forest resources information management function, the biggest advantage of the system is that spatial data and some attributes data can be updated automatically and intelligently, it provides efficient operation platform for forestry management department on forest resources dynamic monitoring, promote intelligent and automation of forest re- sources annual monitoring. This system plays an important role in intensive management of primary forestry department of China.
