中文摘要	全球气候变暖对自然植被生长发育的影响已成为当今世界关注的重要问题.以19822015年植被归一化指数、白天温度(T_(max))、夜间温度(T_(min))、降水量、高程为基础数据,对中国42种自然植被的昼夜增温响应进行研究.结果表明:研究区昼夜增温显著,且不对称性明显,夜间增温速率约为白天温度增速的1.6倍; T_(min)的升高相比T_(max)更利于植被生长,与T_(min)呈正向作用的植被类型占比高出T_(max),且二者存在显著的空间差异;与T_(max)呈正相关作用的植被中亚热带植被占85.7%,而温带高寒、山地、荒漠植被对T_(min)的响应较为明显.T_(min)的升高不利于高海拔地区植被生长发育,而T_(max)则与之相反;植被生长发育与T_(max)、T_(min)的相关性大小分别为:草原>草甸>针叶林>荒漠植被>阔叶林;草甸>荒漠植被>阔叶林>草原>针叶林.
英文摘要	The impact of global warming on the growth and development of natural vegetation is an important concern worldwide. Based on the data from the vegetation normalization index,daytime temperature (T_(max)) ,nighttime temperature (T_(min)) ,precipitation,and elevation from 1982 to 2015, we examined the day-night warming response of 42 types of natural vegetation in China. The results showed that both the temperature at day and night was significantly increased in the study area,with obvious asymmetry. The night warming was about 1.6 times as high as that at daytime. The T_(min) was more conducive to vegetation growth than the T_(max) . The proportion of vegetation types with positive relationship with T_(min) was greater than the T_(max),with significant spatial difference. Subtropical vegetation accounted for 85.7% of vegetation with positive correlation with T_(max) . The temperate alpine, mountainous,and desert vegetation responded more positively to T_(min) . The increase of T_(min) was not conducive to the growth and development of vegetation at high altitudes,while that of T_(max) was the opposite. The correlations of vegetation growth with T_(max) and T_(min) were as follows: steppe > meadow > needleleaf forest > desert vegetation > broadleaf forest; meadow > desert vegetation > broadleaf forest > steppe > needleleaf forest.
