- Abstract:
-
Taking the main greening tree species as the examples in Tianjin City, we analyzed the heavy metal and sulfur contents in leaves. The results showed that the heavy metal pollution degree was in the sequence: Kunlunqiao (urban area) > Shuishang park (suburban Park area) > Ji County (suburban landscape area) > Yangliuqing Manor (outer suburb scenic area), and the pollution degree decreased from center to the outer suburbs, the absorption heavy metal degree of tree leaves decreased in different regions with the sequence: S > As > Pb > Cu > Cr > Cd for tree leaf absorb pollution element in four regions; in Kunlunqiao, each element of absorption ability was strong for Babylonica, absorb lag As and Cr ability were stronger for Sophora japonica, strong ability to absorb Pb and Cr for Populus, absorb ability of Cu and As were stronger for Fraxinus chinensis; in Shuishang Park, Cd and Cr absorption ability was stronger for Sabina chinensis, absorption ability of Cd and As was stronger for Juniperus chinensis, absorption ability of Pb and Cu was stronger for Fraxinus chinensis, S absorption ability was stronger for Babylonica, absorbing ability of Cedrus deodara was stronger for various elements, Populus delay element absorption ability was relatively weak; in Yangliuqing Manor, Cr absorption ability was stronger for Sabina chinensis, Pb absorption ability was stronger for Cedrus deodara and Juniperus chinensis, Populus of Cd and Cu absorption ability were stronger, As and S absorption ability of Eucommia ulmoides was stronger; in Ji County, hysteresis absorption ability of Cr was stronger for Cedrus deodara, absorption ability of Cd, S and Cu was stronger for Populus, the absorption ability of each element was stronger for Babylonica, absorption ability of each element was weak for Juniperus chinensis.
