祁连山青海云杉林空气负氧离子浓度变化及其对气象因素的响应研究
Air Negative Oxygen Ion Concentration of Picea crassifolia Forest in the Qilian Mountains
摘要
Abstract
In order to better help the development of forest health industry in the Qilian Mountains,Picea crassifolia forest distributed in Pailugou watershed of the Qilian Mountains was selected as the research object.The fixed atmospheric negative air(oxygen)ion(NAI)concentration automatic monitor and auto-matic weather station were used to analyze the meteorological factors such as NAI,temperature,relative humidity and rainfall in the forest.The results showed that 1)the annual average concentration of NAI in P.crassifolia forest in the Qilian Mountains was 1 429 cm-3 with a range of 120-3 480 cm-3,and the co-efficient of variation was 43.3％.2)The distribution of NAI concentration in spring,summer and autumn showed a shape of'W',while the distribution of negative NAI concentration in winter showed a'M'shape.The peak value of NAI concentration in spring,autumn and winter appeared at 8:00-11:00,while the peak value of NAI concentration in summer appeared at 19:00-23:00.3)The average diurnal variation of NAI concentration was summer＞spring＞autumn＞winter,with the smallest change in winter and the lar-gest change in summer.4)Pearson correlation coefficient analysis showed that rainfall and relative humidi-ty were significantly and positively correlated with NAI concentration(P＜0.05).The concentration of NAI was linear with temperature,relative humidity and precipitation,and the linear function fitting effect with temperature was poor.The concentration of NAI increased with the increase of relative humidity and precipitation.关键词
