摘要
选择东北岩高兰种群分布的3种典型生境,利用Kestrel 4500,在晴天和间歇性降水天对其分布层的空气温度和空气相对湿度日变化进行测定。结果表明:晴天时,3种生境东北岩高兰分布层的空气温度与相对湿度呈显著负相关;空气温度日变化规律呈现倒U型,空气相对湿度日变化规律呈现U型;相同时点空气温度基本呈现为疏林<林缘<石隙、空气相对湿度基本呈现为疏林>林缘>石隙,且测定时段温湿度日均值呈现相同规律。在间歇性降水天,空气温度与空气相对湿度在相同时点及测定时段日均值均呈现为疏林>林缘>石隙。本研究初步说明东北岩高兰分布的3种典型生境,疏林生境在晴天具有降温与增湿、降雨时具有保温保湿的小气候特征;石隙生境的空气温湿度受天气影响变化幅度较疏林生境、林缘生境大。
Three typical habitats of Empetrum nigrum var.japonicum were selected to determine the diurnal variation of air temperature and relative humidity of the distribution layer on sunny and intermittent rainy days by using Kestrel 4500.The results showed that,on sunny days,there was a significant negative correlation relationship between the air temperature and relative humidity in the distribution layer of Empetrum nigrum var.japonicum in the three habitats.The diurnal variation curves of the air temperature showed the characteristics of inverted U-shaped,and those of the relative air humidity of were U-shaped.On intermittent rainy days,the daily mean values of the air temperature and relative humidity at the same time point and measured period were sparse forest>forest margin>stone gap.This study preliminarily illustrated that the sparse forest habitat had the microclimate characteristics of cooling and humidification on sunny days,and heat preservation and moisturizing during rainfall.The air temperature and humidity of the stone gap habitat was more easily affected by the weather than those of the sparse forest habitat,and the habitat of forest margin was larger than that of the sparse forest habitat.
