杭州西湖山林与市区空气负离子浓度比较研究

Comparative Study of Negative Air Ions of the West Lake Forest and Urban District in Hangzhou

以著名山水城市杭州为研究区域,选取能够体现植物生态效益、标志生态环境优劣、与人体健康相关的空气负离子浓度作为主要测定指标。于2007年11月—2008年10月对杭州西湖山林与市区空气的正、负离子浓度进行了测定,并用相关方法进行评价。研究显示:山林植被提高空气负离子浓度水平显著;人为干扰降低了山林环境空气负离子浓度及清洁度。为保障良好的人居环境,建议市区采取有效措施控制污染、因地制宜加大绿量。

The chosen area for experiments is Hangzhou which is famous for its Shan-shui, and the negative air ions concentration is selected as the key measurement indicator which can represent the ecological benefits of the plants, good or bad of the ecological environment and related human health. During November 2007 to October 2008, positive and negative air ions concentration were measured in the West Lake forest and urban district in Hangzhou and analyzed by the related methods. The results show that： the level of air ions concentration was improved significantly by forest vegetations; lhe anthropogenic environment interference - reduced the mountains air ions concentration and cleanliness. In order to keep the good living environment, urban areas should take effective measures to control pollutions and increase the amount of green space according to local conditions.
