三叠井森林公园空气负离子的时空分布特征

The Feature for Spatial and Temporal Distribution of Aeroanion in Sandiejing Forest Park

对三叠井森林公园内10个具有代表性的景点7∶00—18∶00的空气正、负离子浓度、温度、相对湿度进行测定与分析,并以单极系数和空气离子评价指数为标准对其空气质量进行评价。结果表明:三叠井森林公园空气负离子浓度在7∶00—18∶00时变化特征呈现出两头高、中间低的"V"字形形态;空气负离子浓度与温度呈线性负相关关系,而与空气湿度呈线性正相关关系;空气负离子浓度的空间分布特征为:鸳鸯瀑布>坪溪>奇树湾>古槠亭>竹柏林>鳄鱼潭>天籁谷>状元帽>熊面壁>观景台;所有观测点的空气质量均达到了A级。

Determination and analysis of positive and negative ions air concentration,temperature and relative humidity of 10 representative scenic spots in Sandiejing Forest Park were finished during 7∶ 00～8∶ 00,and this paper made the evaluation on the air quality aeroanion with unipolar coefficient and air ions indexes as the standard.The results showed that the 3 fold well forest park air negative ions concentration presented a two head high with a middle low V glyph form;Air negative ions concentration and temperature had linear negative correlation between the air negative ion concentration and temperature and had positive linear correlation between it and the air humidity;The air negative ions concentration space distribution feature was: Yuanyang Waterfall>Ping Creek>Strange Tree Bay>The Ancient Microphylls Pavilion>Bamboo and Cypress Forest>Crocodile Pond>Sound Valley>Top Hat>Bear Side Wall>Observation Deck.All observed points air quality had reached A level.
