滇中新平磨盘山自然保护区气候特征分析
|
摘要
依据新平站1961—1990年和2007-2016年,杨武站和磨盘山站2013-2017年月降水量、月均温、极端气温、相对湿度等气象资料,采用线性回归方法对保护区东西坡进行对照分析;并采用该方法模拟出磨盘山自然保护区所在地日均温稳定≥10℃的日数随海拔高度变化方程,从而推算出保护区各海拔日均温稳定≥10℃的日数,以此为主要指标,最冷月均温为参考指标,根据《中国气候》的指标体系及划分标准,划分保护区的垂直气候带。结果表明,保护区东坡气温、降水垂直递减率大于西坡;相对湿度随海拔升高呈上升趋势;保护区垂直气候带可划分为山地南亚热带季风气候、山地中亚热带季风气候、山地北亚热带季风气候、山地暖温带季风气候4个气候带。
Based on the meteorological data of monthly precipitation, monthly average temperature, extreme temperature and relative humidity at Yangwu Station and Mopanshan Station from 2013 to 2017 and at Xinping Station from 1961 to 1990 and from 2007 to 2016, the eastern and western slopes of the reserve were compared and analyzed by linear regression method which simulated the equation of stable days keeping the daily average temperature of 10 ℃ or above changing with the altitude. According to the index system and classification standard of China Climate, the vertical climatic zone of the reserve was divided with the mean temperature of the coldest month as the reference index. The results showed that the vertical decline rate of temperature and precipitation on the eastern slope of the reserve was larger than that on the western slope. The relative humidity increased with elevation. The vertical climatic zone in the reserve could be divided into four climatic zones of mountainous southern subtropical monsoon climate, mountainous mid-subtropical monsoon climate, mountainous northern subtropical monsoon climate and mountainous warm temperate monsoon climate.
