摘要
以2003年5月1日至2004年12月13日的降雨、蒸发、日照时数的观测数据为依据,对武夷山自然保护区丝栗栲天然林小气候进行研究。结果表明,武夷山丝栗栲天然林降雨主要集中于5月、6月、8月,月均超过150mm,蒸发主要集中于6-10月,月均超过70 mm,日照时数主要集中于7月、8月、10月,均超过90 h;2003年7月和2004年10月降水量很小,分别为10.1和8 mm,而蒸发量分别为194.4和136.6 mm;蒸发量与日照时数呈正相关,相关系数为88.3%。
Microclimate of natural forest of Castanopsisfargesii in Wuyi Mountain was studied according to observed data of rainfall and evaporation and sunshine duration from May 1,2003 to Dec 13, 2004. The results show that rainfall mainly happens in May, June and Aug. , which overruns 150 mm. Evaporation mainly happens from June to Oct. , which overruns 70 mm, and sunshine duration mainly happens in July, Aug. and Oct. , which overruns 90 h. Precipitation is 10.1 mm and 8 mm respectively in July 2003 and Oct. 2004. Evaporation is 194.4 mm and 136.6 mm respectively. Evaporation is positively correlated with sunshine duration and correlation coefficient is 88.3%.
