| 摘 要： | 以江苏省苏州市森林为研究对象,使用ArcView3.2程序和CITYgreen5.4模型,定量地评价森林生态效益。结果表明:(1)苏州市森林固碳率为1.90×105 t/hm2,暴雨缓排量为1.65×107 m3/hm2,清除大气污染物总量为1.10×104 t/hm2,碳储量为8.42×106 t;(2)2009年苏州市森林生态效益的经济价值总计21.8亿元,各区平均生态效益2.06万元/hm2,固碳、暴雨缓排量、净化空气的经济价值比例分别为87.2%、8.2%及4.6%;(3)苏州市各区森林生态效益的经济价值从大到小排序为:吴中区、吴江市、常熟市、张家港市、昆山市、相城区、太仓市、高新区、工业园区、市区(金阊区、沧浪区、平江区)。

| Abstract: | Ecological benefits of Suzhou forest located in Jiangsu province were assessed based on ArcView3.2 software and CITYgreen5.4 model.The results indicated that carbon sequestration,stormwater runoff reduction,air pollution removal and carbon storage were 1.90×105 t/hm2,1.65×107 m3/hm2,1.10×104 t/hm2 and 8.42×106 t respectively.The ecological benefit reached 21.8 billion yuan in 2009;the average value of ecological benefits was 20.6 thousand yuan/(hm2·a);the proportion of ecological value of carbon sequestration,stormwater runoff reduction and air purification were 87.2 %,8.2 % and 4.6 % respectively in 2009.The order of economic value of ecological benefits in a descending row was Wuzhong,Wujiang,Changshu,Zhangjiagang,Kunshan,Xiangcheng,Taicang,High-tech zone,Industrial site and Downtown area(Jinchang,Canglang and Pingjiang). |
