文摘By measuring the concentration of air anions, thermal-temperature, tree-coverage and bio-diversity in major city greenbelt in Shanghai, this paper analyzed thecorrelativity between air cleaning index and its influential factorsof thesecity greenbelt, and found that less than 60% of parks’ concentration of air inions anions arrived at the general level. There is negative correlation between CI(air clean index) and thermal- temperature, and there is negative correlation between CIand bio-diversity too. Thereis Positivecorrelation between CI and tree-coverage.
