塔里木胡杨自然保护区土地覆盖变化研究

A Study on Land Cover Change of Tarim Populus diversifolia Natural Reserve

塔里木胡杨自然保护区是以胡杨林为主要保护对象的森林生态系统类型的自然保护区,对保护塔里木河中游甚至塔里木河流域生态安全,保持生态平衡等方面都具有举足轻重的作用。从遥感数据入手,对研究区塔里木胡杨自然保护区的土地覆盖/土地利用情况,通过遥感数据分类,结合GPS数据和多年实地照片分析的基础上,获取了研究区近30年的土地利用/土地覆盖变化信息,分析了影响生态环境的自然与人文因子,进一步提出了保护塔里木河岸林的重要性及其保护措施。提出了相应的生态保护与改善措施。

Tarim Populus diversifolia Natural Reserve is mainly targeted at the protection of Populus diversifolia.It plays a decisive role to protect the ecological security of whole Tarim Basin,and maintain the ecological balance,and other aspects.In this paper on the basis of Remote sensing classification data,GPS data and pholographs for years of field,the Tarim Populus diversifolia Natural Reserve land cover/land use change information,the impact of nature and human factors on ecological enveronment was analyzed.The importance of protection of the Tarim River shore and the protection measures were put forward.
