| 摘 要： | 近年来西双版纳大范围的橡胶种植给当地生态环境带来严重影响。利用1957—2017年西双版纳州勐腊县的气候资料以及1980—2017年橡胶种植面积数据,采用气候倾向率估计、滑动t检验和Pearson相关系数等分析方法,研究气候变化特征及其与橡胶种植的关系。结果表明,1957—2017年勐腊县多年平均气温、最高气温、最低气温、相对湿度、降水量、日降水量≥0.1 mm日数分别为21.5℃、29.0℃、17.6℃、83.7%、1528.78 mm和160.7 d;气温、最高气温、最低气温随时间变化呈现显著的上升趋势,相对湿度和降水日数则呈现显著的下降趋势,降水量稍有增加,但增加不明显;西双版纳气候呈现显著的干热化趋势,且干热化趋势在1980年代明显增强,至2000年代中期以后进一步增强;1980年以来,橡胶林种植面积快速增大,且其随时间增大的趋势与当地干热化趋势基本一致;西双版纳橡胶种植面积与气候要素均具有显著的相关关系,大范围橡胶种植在当地气温上升和相对湿度减小的变化中发挥着显著的作用。

| Abstract: | In recent years,the large-scale rubber planting in Xishuangbanna has seriously affected the local ecological environment.Based on the meteorological data from 1957 to 2017 and the rubber planting area from 1980 to 2017 in Mengla County of Xishuangbanna,the climate change characteristics of Xishuangbanna and its relationship with rubber planting were studied by using climate tendency estimation method,sliding t test and Pearson correlation coefficient method.The results showed that the values of mean annual temperature,maximum temperature,minimum temperature,relative humidity,precipitation and mean annual days with average daily precipitation≥0.1 mm were 21.5℃,29℃,17.6℃,83.7%,1528.78 mm and 160.7 d in Mengla County from 1957 to 2017,respectively.The temperature,maximum temperature and minimum temperature increased significantly,while the relative humidity and days with average daily precipitation≥0.1 mm decreased significantly,and the precipitation increased slightly,but not significantly.The climate of Xishuangbanna presented a significant dry-heating trend,which was significantly strengthened in the 1980s and further strengthened after the mid-2000s.Since 1980,the rubber planting area in Xishuangbanna had increased rapidly,which was consistent with the overall and phased changing tendency of local dry-heating trend in time.Significant correlation was found between the rubber planting area and all climate elements.Extensive rubber plantation played an important role in the increase of temperature and the decrease of relative humidity. |
