卧龙森林生态站林内外主要气象因子对比分析研究

采用林外对照区与岷江冷杉林定位观测的实验方法,以卧龙森林生态站气象观测数据为基础,从大气温度、大气相对湿度、土壤温度、降水量、蒸发量、风速和风向等因子对卧龙森林生态站站区林内与林外对照区气象要素值进行对比分析.结果表明:①林内平均大气温度、土壤温度以及降水量相对林外明显偏低;②林内大气温差和林内大气相对湿度变化幅度明显较林外低;③受林地地形条件影响,林外风以东风和北风为主,但林内基本处于静风状态.

Comparison Analysis and Research on Principal Meteorology Factors Inside & Outside Wolong Forest Ecology Station

With located observation both in control plot outside forest and Minjiang fir forest and on the basis of the meteorology data of Wolong forest ecology station,we make comparison analysis of meteorology factors inside Wolong forest ecology station and control plot outside forest from aspects of atmosphere temperature,atmosphere relative humidity,soil temperature,amount of precipitation,amount of evaporation,wind speed and wind direction.The result shows that ① the average temperature,soil temperature and amount of precipitation inside forest are lower than outside forest;② the temperature difference and range of atmosphere relative humidity inside forest are lower than outside forest obviously;③ by reason of the landform,the principal wind is east and north outside forest but the wind is in static state inside forest.
