- 摘要:
- 以天津市主要绿化树种为研究对象，对叶片中重金属元素和硫含量进行了分析。结果表明：各研究区域内重金属污染程度为：昆仑桥（市区） > 水上公园（近郊公园区） > 蓟县（远郊园林区） > 杨柳青庄园（远郊风景区），随着市中心到远郊污染程度降低，不同区域各树种叶片吸滞重金属程度也随之降低，4个区域树木叶片吸滞污染元素排序大致均为：S > As > Pb > Cu > Cr > Cd；在昆仑桥柳树对各元素的吸滞能力均比较强，槐树吸滞As和Cr能力较强，杨树吸滞Pb和Cr能力较强，白蜡吸滞Cu和As能力较强；水上公园桧柏吸滞Cd和Cr能力较强，龙柏吸滞Cd和As能力较强，白蜡对Pb和Cu吸滞能力较强，柳树对S吸滞能力较强，雪松对各种元素的吸滞能力较强，杨树吸滞各元素能力相对较弱；杨柳青庄园桧柏吸滞Cr能力较强，雪松和龙柏吸滞Pb能力较强，杨树对Cd和Cu吸滞能力较强，杜仲对As和S吸滞能力较强；蓟县雪松吸滞Cr的能力较强，杨树吸滞Cd，S和Cu的能力较强，柳树对各元素的吸滞能力均较强，龙柏对各元素吸滞能力均相对较弱。
- 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.
