Abstract
With the current problem of population,resources and environment becoming increasingly intense day by day,the land use/land cover change (LUCC) is one of the core topics on the Present World Change Study.And with the worsening of the global environment,the exhausting of energy and the population explosion,the controversy between the development of oasis economy and the environment has become more and more sharp,which has formed a serious threat to the sustainable development the oasis economy.As a result,the reasonable,coordinate and continuous development is the experimental topic with great theoretical and practical significance in the world.Land use/land cover (LUCC) change has vital significance in environmental variation and the ecology monitoring in the arid and semi-arid areas.This article selects the typical oasis of Awat oasis,which is located in the upstream of Tarim River, where is a typical ecological fragile zone and environmental critical zone.Many effects are caused by the utilization of land and water resources.Along with further development and utilization,great changes of LUCC have been taken place.Based on the research on oasis-desert ecosystem,with the frontier theory of physical geography,LUCC of Awat oasis from 1990 to 2002 are analyzed through the technological train of 3S and statistics,and established the human impact index.Its influencing factors are also identified.First we take the farmland,the wood land,lawn,water,resident,wetland,salt alkali,sand land and naked land as a classification system.Based on the detailed analysis and pretreatment to the remote sensing imagery,we obtained reatively high precision classification result.By the quantification research of human impact to LUCC in Awat,it can be divided into the high human impact area and the low human impact area.The research shows that the changes of pattern are notable and human impact is continuously enhanced,and which is important for the sustainable development of Awat oasis.This research presents the evidence for harmonizing the relations between the land resource and the human activity and provides some methods and experiences for further study of LUCC in aridregion.
