摘要:Air humidity and negative oxygen ion concentration in coniferous (Pinus massoniana), broad-leaved and bamboo forest of the stone signet mountain park in Jingning of Zhejiang were investigated and monitored. The result showed that the negative oxygen ion concentration has a positive relationship with the air humidity in all three forest types, has linear relationship in coniferous(Pinus massoniana) and bamboo forest, and power function relationship in broad-leaved forest.%对浙江省景宁县石印山公园针叶林(马尾松)、阔叶林、竹林3种主要森林类型的空气湿度、空气负氧离子浓度进行监测,结果表明,3种森林类型空气负氧离子浓度与空气湿度呈正相关关系,针叶林(马尾松)、竹林2种植被类型中空气负氧离子浓度与空气湿度呈正比例关系,阔叶林中空气负氧离子浓度与空气湿度呈乘幂关系.
