选择厦门市内不同的棕榈科植物群落类型,比较棕榈植物群落内和林缘间、离静水1 m和5 m处空气负离子密度差异,分析气象因素(主要指空气温度、相对湿度和风速)对空气负离子密度的影响.结果表明:棕榈植物群落内负离子密度显著高于边缘,表明植物群落的存在能有效地提高空气负离子密度;离静水5 m处的空气负离子密度略高于离静水1 m处的,但它们之间的差异未达到显著水平;在多数的观测区内,空气相对湿度与空气负离子密度存在显著的正相关,空气温度与空气负离子密度呈负相关,但多数未达到显著关系;风速不是影响空气负离子密度的因素.

Difference in air ion concentration inside a community, on the edge of a community, in five meters and bne meter away from static water body was studied using different types of Palmae plant communities in Xiamen as research objects.Effects of air temperature, relatively humidity, and wind speed on air negative ion concentration were analysed. Result indicated that air negative ion concentration inside the communities was significantly higher than that on the edge of the communities , indicating that the plant community can effectively increase air negative ion concentrations. Air negative ion concentration in five meters away from static water body was slightly higher than that in one meter away, while the difference did not reach the 0.05 significance level. A significant positive correlation between relative humidity and air negative ion concentration and a negative correlation between air temperature and air negative ion concentration were found in most monitoring areas, but the correlations mostly did not reach the 0.05 significance level. No obvious correlation between wind speed and air negative ion concentration was found.
