【摘要】 运用典型和随机抽样法相结合的方法,对马尾松、湿地松、杨树、栎类、枫香、杉木等6个湖北主要造林树种固碳能力进行了分析,估算出全省人工林固碳总量,结论如下:1、6个树种中杨树、枫香和湿地松固碳能力最强、碳汇前景最好,应大力推广;森林经营管理方式对森林固碳能力有较大影响。2、到2004年湖北省人工林总面积111.56万hm2,蓄积量4307万m3,人工林累计吸收5805.9万t二氧化碳。3、湖北省2004年排放工业二氧化碳2.09亿t,人工林年均吸收二氧化碳193.59万吨,湖北省现有33.3万hm2荒山无林地,若选用杨树等6树种造林,每年将增加47.62万t二氧化碳吸收能力。更多还原

【Abstract】 The carbon sequestration ability of six trees in hubei was analyzed by using the typical and random sampling method, the trees were pinus massoniana , pinus ellilotti , poplar, robbur, liquidamber formosana and cunningghomia, and the quantity estimating was made for the total forestry carbon sequestration, the conclusion was as follows: 1, poplar , liquidambar formosana and pinus ellilotti carbon sequestration ability was strong, and the carbon sequestration prospects were the best, they should be popularized, Forest management mode has greater influence on the ability of forest carbon sequestration. 2, In 2004, there were 111.56 million hectares of afforestions’ area with volume of 43.07 million cubic meters in hubei province, plantation absorbing co2 cumulated 58.059 million tons. 3, In 2004, industrial carbon dioxide emissions in hubei province was annual 2.09 hundred million tons and 193.59 tons of carbon dioxide were absorbed by the plantations. There still were 3.33 hundred thousand ha barren hills , it should increase ability of 4.762 hundred thousand tons to absorpting co2 if such as poplar should be selected as afforestions’species.更多还原
