昆明官渡古镇法定寺周边绿地生态效益分析

Analysis on Ecological Benefits of the Greenspace Around Fading Temple in Guandu Ancient Town of Kunming City

运用Arc View 3.2和CITYgreen 5.0模型对昆明市官渡古镇内法定寺周边休闲绿地进行生态效益的量化分析,并利用该软件的生长模拟功能对10a后的生态效益进行了预测。结果表明:该休闲绿地与周围建筑及附属设施布局合理,绿地植物整体生长良好,较好地发挥了对环境的改善作用。该绿地碳储存量为25.25t,2010年碳吸收总量0.52t,植被释放氧气1.39t,清除大气污染物32.93kg。模拟得出2020年其碳储存量累积达到55.09t,碳吸收量1.24t,释放氧气3.31t,清除大气污染物71.82kg。

A quantitative analysis on partial ecological benefits produced by the recreational green-space around Fading Temple in Guandu Ancient Towns,Kunming City in the year of 2010 was conducted by means of applying ArcView 3.2 software and CITYgreen 5.0 model,and the partial ecological benefits that would be generated in 2020 was forecast by growth simulation with the model.The results showed that the green-space matched well with the buildings and other peripheral facilities,and the plants in the green-space were generally in good growth status.The total carbon storage of this green-space by 2010 was 25.25 t,the carbon sequestration quantity in the year of 2010 was 0.52 t,the O2 release quantity of the plants in 2010 was 1.39 t,and the quantity of air pollutants removed in 2010 was 32.93 kg.The simulation showed that in 2020 the carbon storage of the green-space will be accumulated to 55.09 t,the carbon sequestration quantity in the year of 2020 would amount to 1.24 t,the O2 release quantity will amount to 3.31 t,and the quantity of air pollutant removal in 2020 would amount to 71.82 kg.
