内蒙古自治区森林净初级生产力GIS空间数据库的建立

摘要

In this paper, on the basis of collecting a large number of net primary productivity of forest to GIS technology as a means, using the integrated GIS software Arcview which developed by the U. S. Environmental Systems Research Institute （ESRI）, completed the Inner Mongolia Autonomous Region GIS forest net primary productivity Spatial Database. The database includes vector database and attribute database in two parts. This database is more comprehensive and systematic studying of forest net primary productivity reflects the basic information for further net productivity of forests to conduct inquiries to establish the system to provide basic information.%文章以GIS技术为手段，在收集大量有关森林净初级生产力资料的基础上，采用的是美国环境系统研究所（ESRI）开发研制的集成地理信息系统软件Arcview，完成了内蒙古自治区森林净生产力GIS空间数据库的建立。该数据库包括矢量数据库和属性数据库两部分。此数据库比较全面、系统地反映出研究区森林净生产力的基本信息，为下一步要进行的森林净生产力查询系统的建立提供基础资料。
