中国中部典型半湿润半干旱区近40年来气候变化特征
The climate change characteristics in typical semi-humid and semi-arid areas in central China during recent 40 years
摘要
Abstract
Characteristics of climate changes in recent 40 years in Xinmi City that locates in typical semi - humid and semi-arid areas within central China were analyzed. The muti-approaches included linear trend, accumulative departure curve and Mann-Kendall test method were used to analyze the trends and mutations by the annual and seasonal mean temperatues, evaporation and precipitation from 1971 to 2010. The results indicated that the annual and seasonal mean temperatures continually increased, and the average linear temperature change rate was 0.44 ℃/l0a which meant annual average temperature increased 1. 8℃ from 1971 to 2010, the annual and seasonal average evaporation decreased fluctuatly, annual precipitation had no significant increasing or decreasing trends and seasonal variations of precipitation trends were different from each other. These variations are consistent with climate changes in China under global warming sence, but decadal change of the seasons is slightly different.关键词
