| 摘 要： | 通过测量上海主要公园绿地的空气正、负离子、下垫面热辐射温度、森林覆盖率及生物多样性的指标,研究分析了城市绿地的空气清洁度指数(CI)与其影响因素的相关关系。结果发现,上海仅有不到60%的公园空气负离子浓度达到一般城市公园水平;空气清洁度与热辐射温度之间存在指数负相关;空气清洁度与森林覆盖率之间存在指数正相关;空气清洁度与生物多样性之间亦有较强的正相关。

| Abstract: | By measuring the concentration of air anions, thermal-temperature, tree-coverage and creature-diversity in major city greenbelt of Shanghai, the correlativity between air cleaning index and its influential factors of these city greenbelt was analyzed in this paper and it was found that the air anion concentration of less than 60 percent parks arrived at the average level of general city. There was a negative correlation between air clean-index (CI) and thermal-temperature, a plus correlation between CI and tree-coverage, and a negative correlation between CI and creature-diversity. |
