摘要
上海林地和绿地的土壤碳含量较低,固碳能力约为7.5万t/年。通过植树造林增加碳汇的潜力有限。建议通过加强森林抚育提高森林碳储量和碳密度;探索多元化的城市林业建设方式;因地制宜发展立体绿化,提高城市绿量;实施节约型园林绿化管理模式等措施来提高碳存储能力。
Soil carbon content in forest land and green land system of Shanghai is low and the carbon sequestration capacity is about 75 000 t/a.There is limited potential to increase carbon sequestration by increasing forest area through afforestation.With the view to improving carbon storage capacity,it was recommended to adopt measures including strengthening forest resources management to enhance the carbon storage and density,exploring a wide range of approaches to develop urban forestry,developing in line with local conditions three-dimensional green system to increase urban green biomass,implementing resources-saving urban landscape management,etc.
