摘要
为研究湿季不同林分空气负离子浓度的变化规律及其影响因素,选取三亚南岛森林康养基地同一海拔的4种林分类型和不同海拔梯度的常绿阔叶林、槟榔林为研究对象,采用空气负氧离子检测仪及气象记录仪在7—9月份进行数据监测,并对数据进行单因素方差分析、多重比较及相关性分析。结果表明:1)4种林分空气负离子浓度日变化均呈双峰型,不同林分间存在极显著差异,其均值从高到低的排序为橡胶林>常绿阔叶林>槟榔林>母生林,群落结构越复杂、郁闭度越高,负离子变异性越小。2)受植物自身生理特性、群落结构等的影响,不同林分空气负离子浓度与微气候具有不同的线性相关关系。3)常绿阔叶林、槟榔林负离子浓度与海拔呈显著性负相关,槟榔林负离子浓度变异系数与海拔呈正相关。因此,4种不同林分中,橡胶林的康养效果最佳,其次为常绿阔叶林,今后在森林康养旅游中,可优先选择这两种林分进行游憩。
In order to study the changing pattern of negative air ion concentration at different stands in wet season and its influencing factors,4 types of forest at the same altitude as well as evergreen broad-leaved forest and Areca catechu forest at different altitudes are selected in Nandao Forest-based Health Base,and the data about negative air ion are monitored from July to September using negative air ion detector and aerograph and analyzed with one-way ANOVA,multiple comparisons and correlation analysis.The results show that:1)The diurnal variations of negative air ion concentration in the types of forest stand present a bimodal pattern,and there are extremely significant differences among different stands.The mean values are ranked from high to low as rubber plantation>evergreen broad-leaved forest>A.catechu forest>Homalium hainanense forest.The more complex the community structure and the higher the canopy density,the smaller the negative air ion variability;2)Affected by the physiological characteristics and community structure of plants,the concentrations of negative air ions in different stands have different linear correlations with microclimate;and 3)The negative air ion concentrations in the evergreen broadleaved forest and A.catechu forest are significantly negatively correlated with the altitude,and the variation coefficient of negative air ion concentration in A.catechu forest is positively correlated with the altitude.It can be seen that among the 4 types of forest stands,the rubber forest has the best effect in forest-based health and wellness,followed by the evergreen broad-leaved forest.Therefore,the two types of forests can be preferred for recreation activities to achieve forest-based health.
