摘要: 以新疆于田绿洲为例,以Landsat TM/ETM+为基础数据源,利用空间分析方法、3S技术方法等定量分析于田绿洲平均温度的分布特征,得出地表温度受下垫面类型的影响比较明显,地表土地类型的分布基本决定地温的总体分布;通过对温度相异图的研究,发现温度的分布同时也受到不同土地利用类型空间分布的影响;对克里雅河下游河段进行温度变化的趋势分析,得出在南北方向上,没有温度变化趋势,而在东西方向上,温度变化比较明显。同时也说明克里雅河对其河道两边的影响范围十分有限。

Abstract: Oasis is a unique geographical system in the arid area, which is stricted by the material and energy flow of the Mountain-Oasis-Desertification system. So, it should focus on the study of the interaction process between the Mountain-Oasis-Desertification system, including the flow of energy among the oasis, desert and the mountains. This paper takes Yutian Oasis as an example, using Landsat TM/ETM+ as the data source and the temperature as an index to study the interaction process of the Mountain-Oasis-Desertification system. The article analyzed the oasis average temperature distribution, and the result showed that the surface temperature is determined obviously by underlying surface type and surface land type distribution influences the overall distribution of land temperature. Through the different temperature chart, it is found that the distribution of temperature is impacted by the spatial distribution of different land use types. The temperature trend analysis on Keriya River downstream obtained the result that in the north-south direction, there is no temperature change, and in east-west direction, the temperature changes obviously. Meanwhile, the influence range to both channel of Keriya River is limited.
