摘要
为探明信阳市不同生境空气负离子浓度的变化规律,2012年3月至2013年2月采用定位观测的方法,对信阳市3种不同生境条件下空气负离子浓度进行了连续测定。结果表明:林木生长旺盛的夏季,森林生境内空气负离子浓度均值在不同天气条件下表现为晴天>多云>阴天,不同林分表现为落叶阔叶林>针阔混交林>落叶针叶林>竹林,1年中季节变化表现为夏季>秋季>春季>冬季;不同生境条件下空气负离子浓度年均值差异显著(P<0.05),表现为森林(704个·cm-3)>市内公园(479个·cm-3)>公交车站(217个·cm-3)。由此表明,林分、天气、季节和生境对空气负离子浓度有一定的影响,研究结果可为城市的规划建设、植物配置以及景区开发提供参考。
For finding variation of the aeroanion concentration in the different habitat in Xinyang.,It was measured with continuing site-specific observation in March 2012 to February 2013. The results show that： in summer larging volume of forest growth season, the aeroanion concentration in the different weather conditions was：sura,y〉cloudy〉overcast; the average of the aeroanion concentration in different forest types decreased in the order as follows： deciduons broad-leaved forests〉coniferous and broad-leaved mixed forest〉deciduous coniferous forest〉bamboo forest; the average of the aeroanion concentration in different season decreased in the order as follows： summer〉autumn 〉 spring〉winter. The results showed that differed significantly of the aeroanion concentration in differem habitat decreased in the order as follows： forestry （ 704 ） 〉urban park （ 479 ） 〉bus station （ 217 ） . The results showed that the forest types, weather, seasons, habitat has certain influence to the concentration of aeroanion the study can provide some reference for city planning and construction, plant configuration and development of the scenic spot.
