摘要
本文利用2001年～2010年MODIS地表温度8天合成产品,与新疆玛纳斯河流域DEM数据进行叠置分析,得到该流域不同高程、坡度、坡向下的地表温度在年内的变化情况。通过分析其变化特征发现,地表温度受三者的影响在不同的时间段是不同的,为进一步研究地表温度在时间上的变化机理提供了理论参考。
The inner-annual variation of LST (Land Surface Temperature)in mountainous area of Manas river basin is studied based on LST of different altitude,slope and aspect acquired from remotely sensed land surface temperature product (MOD11A2)from 2001 to 2010 and the area’s DEM(Digital Elevation Model)data.It has been found LST is affected by the three factors differently in different time that can be helpful for further studying of rules of LST’s changing in time scale.
