中文摘要	土地利用/土地覆被变化对干旱区生态环境变化有明确的指示意义。基于台特玛湖地区1988-2017年Landsat遥感数据、土地利用数据和气象站观测数据,运用均值法、线性趋势分析法、 Pearson相关性分析法、主成分分析法等,分析了近30 a来台特玛湖地区土地利用/土地覆被类型、植被NDVI(Normalized difference vegetation index)变化及其影响因素。结果表明:土地利用/土地覆被以草地为主,草地和耕地面积均呈下降趋势,林地呈上升趋势;植被NDVI总体呈上升趋势,但上升趋势较缓;植被NDVI整体偏低,仅在台特玛湖湖区周围水分条件比较好的地区稍高;植被NDVI与气温和降水具有一定相关性;生态输水对该地区的植被状况改善起到了促进作用。
英文摘要	Changes in land use/land cover are a clear indication of changes in the ecological environment of arid areas.This paper utilizes land use data,on the basis of Landsat remote sensing data with a spatial resolution of 30 m,and observation data from meteorological stations in the Taitema Lake region,South Xinjiang,China between 1988 and 2017 to study the Kanlake wet land,approximately 30-km northwest of Taitema Lake,that was formed after the Taitema Lake and Qarqan River changed course.The land use/land cover type and the vegetation NDVI(Normalized difference vegetation index) change and its influencing factors in the Taitema Lake area over the past 30 years have been analyzed using the mean value method,the linear trend analysis method,the Pearson correlation analysis method,and the principal component analysis method.The results show that the land use / land cover has been dominated by grassland.The area of grassland and cultivated land showed a decreasing trend, whereas that of woodland showed an increasing trend.The NDVI of the vegetation showed an overall increasing trend,but this increasing trend was slow,which indicates that the ecological environment in this region has,on the whole,been developing toward improvement.The NDVI of the vegetation was also generally low,and it was only slightly higher in the area with good water conditions around Taitema Lake;the vegetation NDVI is restricted by both water and heat conditions,among which the effects of the lake temperature and relative humidity are more significant.The variation of the grassland NDVI is significantly affected by spring temperature and summer precipitation,and the NDVI of the forest land and cultivated land is less affected by natural factors.Ecological water transport has promoted the improvement of vegetation in this area.Further study of the evolution of the ecological environment and its corresponding relationship with influence factors in Taitema Lake area is needed both to formulate measures of vegetation recovery and growth in the study area in the construction of an ecological security barrier and the development of scientific and rational uses of water and land resources and to explore both the harmonious relationship between human activities and the evolution of the ecological environment and the scientific understanding of the region's ecological environment status and existing problems.This paper is of important theoretical and practical significance,and it provides a data basis for carrying out ecological protection and ecological planning,both in theory and practice,and a scientific basis for the sustainable development of the economy and society,the effective protection of the ecological environment,and the sustainable utilization of natural resources in the Taitema Lake area.It also has important strategic significance in the promotion of the coordinated development of society,the economy,the environment,and various resources in the future,as well as in the construction of national sustainable development.
