森林空气负离子浓度与环境温湿度指数的关系研究
Research on Relationship between Forest Negative Air Ion Concentration and Temperature and Humidity Index
摘要
Abstract
In order to study the influencing factors of forest air negative ion concentration and its natural environment , Hei-longjiang forest botanical garden was used as the research object .Using GIS and statistical analysis method , with the help of a new comprehensive index: temperature and humidity index ( THI) , the relationship between negative air ion concentration and THI was an-alyzed in the botanical garden .The effects of environmental temperature and humidity index on the negative air ion concentration in different plant structure were also analyzed .The results showed that: (1) in Heilongjiang forest botanical garden , negative air concen-tration is proportional to the complexity of plant structure , the concentrations of negative air ion from high to low botanical constitution :shrub-tree-herb community>shrub-tree community >tree-herb community >shrub-herb community >tree community >shrub community>herb community.(2)The concentration of negative air ions increased first and then decreased with the increase of the en -vironmental THI.When the THI is about 800, forest negative air ion concentration reached the highest .(3)The effect of THI on the negative air ion concentration in different plant structure environment is different , the more complex the plant structure , the greater the effect.The study can provide a reference for further analysis of the influencing factors of forest air negative ion concentration , and the temperature and humidity in natural conditions are combined into a new index , environmental temperature and humidity index ( THI) , which could provide a new method and idea for the construction of the index system of negative air ion concentration .关键词
