摘　　要：受环境因素与人类活动的影响,塔里木河中游地区近年植被长势及分布变化较大,通过对植被的动态监测分析,可为塔里木河生态保育对策的制定及植被保护研究提供科学依据.本文采用面向对象的Geodatabase模型,使用地理信息系统(GIS)对空间、属性数据的管理分析功能,以塔里木河中游为研究区,选取通过遥感图像处理平台ENVI计算得到的2000、2006、2010、2015年四期归一化植被指数(NDVI)为研究数据,通过使用Arc GIS对NDVI进行空间分布特征研究,设计出一种塔里木河中游植被指数空间数据库,以实现空间、属性数据的存储管理一体化.该植被指数空间数据库能直观的反映出研究区植被变化及生长情况.Due to the environment and human activities, the growth and distribution of vegetation has a great change in the middle reaches of the Tarim River. We can monitoring the vegetation growth and distribution in the middle reaches of the Tarim River to provide a scientific and reliable basis for the enactment of the ecological conservation policy and vegetation protection in the middle reaches of the Tarim River. This paper adopts the object-oriented Geodatabase model, using geographic information system （GIS） to analysis spatial data and attribute data of the middle reaches of the Tarim River, selecting the normalized difference vegetation index （NDVI） in 2000, 2006, 2010, 2015 as the research data which is calculated through the remote sensing image processing platform ENVI, using ArcGIS for the research of the spatial distribution characteristics of NDVI. This paper designs a vegetation index spatial database based on Geodatabase for middle reaches of Tarim River to accomplish the integration of storage and management of spatial data and attribute data. This spatial database can reflect the changes of vegetation growth and distribution directly in the study area.
