| 摘 要： | 海南尖峰岭热带山地雨林作为典型的热带雨林生态系统之一，其长期的气候动态变化研究对全球变化研究有着重要的作用。采用1980--2005年海南尖峰岭森林生态系统国家野外科学观测研究站天池气象站地面常规气象观测资料，利用累积距平法和Mann—Kendall检验法分析了尖峰岭热带山地雨林区气候突变和气候异常。结果表明：近26a来，该区年平均气温、年平均地温、年平均最高最低气温、年积温和平均水汽压在1990年前后经历一次由低到高的突变，年平均风速在1993年经历由大到小的突变。在高强度ENSO事件发生的1998年，气温、地温均出现异常偏高，这些都表明该林区的森林气候变化正是对全球气候异常的明显响应过程。

| Abstract: | Jianfengling tropical mountain rainforest （JTMR） in Hainan province is one of the typical tropical forest ecosystems, whose long term climatic dynamics is important to the global change research. Based on the conventional meteorological data of national field observation station in Jianfengling tropical forest ecosystem from 1980 to 2005, the abrupt change and anomaly of climate in JTMR were analyzed by the accumulative anomaly method and Mann-Kendall test. The results show that the annual mean air/ground temperatures, the annual mean maximum and minimum air temperatures ,the annual accumulated temperature and the mean vapor pressure change from the low to the high during recent 26 years, and the abrupt change occurs in 1990. The mean annual wind speed changes from strong to weak,and the abrupt change appears in 1993. Air temperature and ground temperature are high abnormally when the strong intensity ENSO event happens in 1998. All of these mentioned above indicate that the climatic change of forest land is just the significant response to the global abnormal climate change. |
