摘    要全球气候变暖，区域地表热环境和人类戚戚相关，除了人类要素为主导的地表热环境改变，自然因素对地表热环境甚至全球环境的影响也有待关注。本文以浙江省为研究区，以自然环境要素为主，分析植被覆盖度、地质构造带、岩石土壤等因子对区域地表热环境格局分布带来的影响。本研究使用了2013-2014年8景覆盖浙江省全域的Landsat-8 OLI影像，对其进行LST（Land Surface Temperature）反演，在增强自然要素的背景下，研究各要素对地表热环境的作用，结果表明：（1）植被覆盖度与地表温度呈显著负相关，覆盖度越高，地表温度越低。尤其当植被覆盖度由0%~10%演变到10%~30%时，植被的降温效果最为显著，而且该作用在植被覆盖普遍较低区域更加明显；（2）断裂带对地热格局的影响呈倒“V”型，即在断裂带附近升温随距离降温达到温度谷值，该作用在单一断裂带上表现明显；（3）岩石和土壤的多样性和差异性，形成了地表覆被状况的差异，其间接影响地热格局的分布。早燕山期岩浆岩多发育为黄红壤，相对晚燕山期岩浆岩，两时期地表平均温度差幅达到1。74℃；（4）黄红壤在研究区分布最为广泛，其温度特性也最能表征研究区地表热环境分布格局，该土层上植被覆盖较为均匀，其在最低温度上的降温效果最为显著。通过探究这4个因子对地热格局分布的影响，指出岩石土壤对地表的作用依托于植被，而植被对地表的降温作用最为直观和显著；断裂带对地表的升温作用明显，可帮助寻找地热泉点，探明地热储备。89524

Abstract

The global climate warming and the regional surface heat environment are closely related with human works。 In addition to human factors as the leading surface heat environment change, natural factors even need to be focused on。 This paper, taking Zhejiang province as the research area, give priority to with natural environmental elements, analysis of the vegetation fraction, geological tectonic belt, rock soil factors such as the impact of regional surface pattern of heat environment change。 Using 8 Landsat OLI Images during 2013-2014, retrieved LST。 With enhancing the role of natural factors effect on surface heat environment, conclude: (1) Vegetation fraction and the surface temperature has significant negative correlation, the higher the coverage, the lower the surface temperature。 Especially when the vegetation fraction from 0% ~ 10% to 10% ~ 30%, the cooling effect of vegetation is most significant, and this effect was more obvious in the area with low vegetation fraction;(2) The influence of the fault zone on the geothermal pattern is inverted "V" type, that is, in the vicinity of the fault zone, the temperature rise decreases with the distance to reach the temperature valley value, and the effect is obvious in the single fault zone ;(3) The persity and difference of rock and soil formed the difference of surface cover, which indirectly affected the distribution of geothermal pattern。 In the early Yanshan period, the magmatic rocks are mostly developed in yellow red soil and relatively late Yanshan magmatic rocks, and the mean temperature difference between the two periods is up to 1。74 ℃;(4) The distribution of yellow red soil in the study area is the most extensive, and its temperature characteristics can best represent the distribution pattern of the surface heat environment。 The vegetation fraction is more uniform on the soil layer, and its cooling effect is the most significant at the lowest temperature。 Through the research of these 4 factors on the geothermal distribution pattern, pointed out that the effect of rock and soil on the surface based on the vegetation, and the cooling effect of vegetation on the surface of the most direct and significant effect on the surface temperature; fracture zone is obvious, can help to find the hot springs and geothermal proven reserves。
