城市热岛强度（UHII）是量化城市热岛效应大小的关键指标。然而，UHII的变化可能受到城市或农村温度变化的影响，或两者兼而有之。许多研究已经调查了UHII的变化，但它如何与城市和农村温度的变化关系却知之甚少。本文对2000 - 2015年中国31个主要城市的UHII变化进行了大陆尺度分析，并进一步探讨了这种变化是否由城市变暖引起。利用MODIS陆面温度产品（MOD 11 A2）进行夏季时间序列分析。我们发现：（1）2000 - 2015年，大部分城市（31个中的25个）的城市热岛指数呈上升趋势，其中44%的城市热岛指数显著上升，表明城市热岛效应显著增强。(2)UHII的加剧并不一定意味着城市热环境的恶化，反之亦然。在UHII呈上升趋势的25个城市中，11个城市的LST在城市和农村地区均呈下降趋势。与此同时，在UHII呈下降趋势的6个城市中，有3个城市的城市和农村地区均呈变暖趋势。(3)城市热岛指数变化与城市和农村地表温度变化的关系表明，要充分量化城市化对城市热岛效应的影响，必须量化城市和农村地表温度的变化。
Intensity of urban heat island (UHII) is a key indicator to quantify the magnitude of UHI effect. Change in UHII, however, can be affected by change in urban or rural temperature, or both. Numerous studies have investigated the change of UHII, but how it relates to change in urban and rural temperature is poorly understood. Here we present a continental scale analysis on the change in UHII from 2000 to 2015 in 31 major cities in China, and further explored whether such change was caused by urban warming. We used time series analysis based on MODIS land surface temperature product (MOD11A2) in summer. We found: (1) A majority of the cities (25 out of 31) had an increasing trend in UHII from 2000 to 2015, among which 44% were significant, suggesting a significantly intensified UHI effects. (2) Intensified UHII does not necessarily mean deterioration of urban thermal environment, and vice versa. For the 25 cities with an increasing trend in UHII, 11 cities had a decreasing trend of LST in both urban and rural areas. Meanwhile, for the 6 cities with a decreasing trend in UHII, three had warming trend in both urban and rural areas. (3) The attribution of changes in UHII to that of urban and rural LST indicated that it is necessary to quantify the change of LST in both urban and rural areas to fully quantify the impact of urbanization on UHI effect.
