【摘要】 以基于GIS为基础的城市植被分析软件———CITYgreen的要求对沈阳市建成区进行调查,并统计分析,获得沈阳市建成区绿色覆盖现状,各用地类型植被的环境效益以及沈阳市建成区的总体环境效益。结果表明,沈阳市建成区的绿色覆盖(树冠与草地之和)率以绿化类用地最高;植被净化效益的主体为树木覆盖,植被环境效益与树冠覆盖比呈现正相关关系,单位面积的净化效益以绿化用地最高,商业金融用地最低;建成区总碳贮存为199 485.4t,每年的碳存留为879.6478t,O3的去除量为71 283.89kg,SO2的去除量为22 163.97kg,NO2的去除量为40 876.3kg,PM10的去除量为61 494.02kg,CO的去除量为8 149.331kg。该文还对提高环境质量提出建议。更多还原

【Abstract】 Based on CITYgreen software,urban vegetation of Shenyang built-up areas was investigated by statistic and analysis,and vegetation conditions and environmental benefits of land types in built-up areas were obtained.The result showed that in built-up areas the green percentage（the sum of canopy and grassland） for greening lands was the highest,and the main body of environmental benefits was tree,and the correlation between environmental benefits of vegetation in Shenyang built-up areas and its canopy percentage was positive,and purification benefits per hectare of green lands took the first place,and that of commercial financial land use took the last place,and carbon storage in Shenyang built-up areas was 199 485.4t,carbon sequestration rate was 879.6478t per year,and removal quantities for O₃,SO₂,NO₂,PM10 and CO was 71 283.89kg,22 163.97kg,（40 876.3kg）,61 494.02kg and 8 149.331kg respectively.Some advice was put forward in this paper to improve environmental quality.更多还原
