浙江省桐乡市森林碳汇探讨

Study on Forest Carbon Sink of Tongxiang of Zhejiang Province

根据桐乡市森林资源清查等资料,结合实地调查,对桐乡森林资源的生态碳汇功能及前景进行了分析及建议。桐乡市森林生物量总碳汇约为24.4万吨,森林碳密度约为20.97吨/公顷;森林净初级生产力以碳量计算约为8万吨/年,森林土壤碳密度约为56.02吨/公顷,结果显示提高森林碳密度和土壤碳密度是增加桐乡市森林碳汇的有效手段。

Tongxiang City of Zhejiang province,located in Hangzhou-Jiaxin-Huzhou Plain,has developed quickly.Based on the data from the forest resource inventory of Tongxiang city and on-the-spot investigations,this paper studies the function and prospect of its forest carbon sink.Tongxiang City,the total forest biomass of about 244,000 tons of carbon sinks,forest carbon density of about 20.97 tons/ha;net primary productivity of forest carbon calculation is about 8 million tons/year,forest soil carbon density of about 56.02 t/ha.The result shows that it is important to increase forest coverage,forest carbon density and soil carbon density for increasing urban forest carbon sink.
