摘要

为了辨析博斯腾湖流域地表温度时空分布对不同下垫面的响应特征，基于MODIS数据，利用分裂窗算法反演研究区的不同季节地表温度并对反演结果进行精度检验。结果表明：① MODIS地表温度产品在博斯腾湖流域的精度良好，可利用流域地表温度的空间格局研究；② 博斯腾湖流域四季地表温度变化显著，春季温度分布在-17.02～31.52 ℃ 之间，夏季温度分布在 -9.99～56.04 ℃ 之间，秋季温度分布在-16.45～37.31 ℃之间，冬季温度分布在-32.42～10.79 ℃之间；③ 不同土地利用地表温度的分布总体上沙漠/沙地的地表温度均值最高，旱地、裸岩等次之，积雪、草甸最低。内陆湖流域内地表温度和土地覆盖类型存在明显的时空差异性，在极端干旱地区绿色植被对温度降低具有一定的调节作用。

Abstract

In order to discriminate the response of the land surface temperature (LST) to underlying surface of Bosten lake watershed area

the land surface temperatures are calculated by MODIS split window algorithm and validated using observed metrological data. The results show that：① MODIS LST product is applicable for the analysis of spatio-temporal distribution characteristics of LST in Bosten Lake watershed area. ② The distribution of land surface temperatures is very different in different seasons and different regions. The land surface temperature varies between -17.02 ℃ and 31.52 ℃ in spring

between -9.99 ℃ and 5604 ℃ in summer

between -16.45 ℃ and 37.31 ℃ in autumn

and between -32.42 ℃ and 10.79 ℃ in winter. ③ Spatial distribution of land surface temperature is related to land use types

which have affected the land surface temperature distribution in the study area. The highest LST is distributed in the desert/sandy land and the lowest LST distributed in glaciers and meadow area. The spatiotemporal distribution of LST is closely related to LUCC in the inland lake basins

and the green vegetation has the function of regulating climate and temperature in the oasis region

which is extremely vulnerable to the ecological environment of the arid region.
