蓝山县乔木林碳贮量及固碳价值研究

以蓝山县十二五森林资源调查成果为数据依据,对蓝山县不同类型乔木林碳贮量及固碳价值进行了研究。结果表明:蓝山县乔木林的总碳贮量为169.37×104t,固碳价值为203 244万元。杉木的碳贮量最大,占乔木林总碳贮量的67.58%。阔叶林的碳密度普遍大于针叶林的碳密度。幼龄林碳贮量最大,不同龄组碳密度符合近、成、过熟林大于中、幼龄林的规律。人工林的碳贮量占绝对优势,天然林的碳密度大于人工林。

Carbon storage and economic value assessment of highwood in Lanshan County

A research on carbon storage and economic value assessment of different type highwood is performed according to the Twelfth Five-Year Plan forest management inventory of Lanshan County. The result show that the carbon storage of Lanshan’s highwood total 169.37 ×104 t,the economic benefit of fixation carbon dioxide is 2 032.44 million yuan. The biggest carbon storage was Cunninghamia lanceolata plantations,accounted for 67.58% of total carbon storage of high-wood. The carbon density of broad-leaved fore is greater than that of coniferous forest. The biggest carbon storage is young forest in different age groups,and the carbon density,in accordance with near-mature forest,mature forest and over ripe-ness forest is greater than half-mature forest and young forest. The carbon storage of planted forest is largest absolute ad-vantage ,but the carbon density of natural forest is greater than that of planted forest.
