文章利用1972年、1990年和2010年的遥感数据，采用GIS空间分析技术与计量地理学方法对精河流域绿洲的土地利用结构和空间格局现状及其变化进行了定量分析，并对土地利用结构现状和土地利用结构变化两方面做了相关研究。结果表明：（1）研究区在三个年份均为高多样化地区，说明该区域土地利用类型较多，即齐全程度较高；（2）研究区土地利用组合类型数较少，三个时期均只有3种，且未利用地、草地占绝对优势，区域土地整体功能较弱，体现了干旱区流域绿洲的特点；（3）土地利用程度指数较低，变化较大，总体略有上升；（4）土地利用信息熵总体增加，土地利用类型处于调整期，但增加速率降低，土地利用无序性减小。

In this paper, It uses GIS spatial analysis techniques and methods of quantitative geography oasis Jinghe River Basin land use quantity structure and spatial patterns of changes in the status and its quantitative anal?ysis by remote sensing data of 1972, 1990 and 2013. The research mainly about land-use structure and structural changes . The results show that:(1) the study area are highly diverse region in the three years , this indicate that it has many types, namely the extent to which the higher range of regional land use;(2) a combination of the type of land use is fewer and only three, and most of it are grassland dominant, the overall function of the land area is weak, reflecting the characteristics of the river basin in arid areas oasis;(3)the land use degree index of the study area is not high, but changes is so large in three periods and the overall slight is increasing;(4)land use informa?tion entropy is overall increasing;land use types is in the adjustment period, but the rate of increase is reducing and land use disorder is decreasing.
