摘　　要：以干旱绿洲区石河子市为例,通过获取2009年、2016年土地利用类型信息,分析了其土地利用和生态环境动态变化情况。结果表明,8 a间石河子市不同土地利用类型之间的转换复杂,且速度不一;石河子市耕地面积减少最多,城镇及工矿用地面积增加最多;林地、交通运输用地变化最快,动态度分别为46.27%和19.56%;石河子市生态环境质量有所下降,由2009年的0.313下降到2016年的0.293,下降幅度较小。总体来说,在石河子市城市化进程中,城市绿化和环境保护起到了积极改善生态环境的作用;人类对美好生态环境的需求和建设生态城市的目标越来越明晰。Taking Shihezi City in the arid oasis region for example, we analyzed the dynamic changes of land use and ecological environment by obtaining the information of land use type in 2009 and 2016. The results showed that in the past 8 years, the conversions between different land use types in Shihezi City were complicated and the speeds of change were different. The area of cultivated land in Shihezi City decreased the most, while the area of urban and industrial and mining land increased the most. From the perspective of dynamics, forest and transportation land had the fastest changes, the dynamic degree were 46.27 % and 19.56 % respectively. In terms of ecological environment, the ecological environment quality of Shihezi City decreased, from 0.313 in 2009 to 0.293 in 2016. In general, among the continuous urbanization in Shihezi City, urban afforestation and environmental protection have played a positive role in improving the ecological environment. The human needs for a better ecological environment and the goal of building an ecological city are increasingly clear.
