摘要:
 以陕西省退耕还林工程阶段验收成果为依据，按照陕西南部和北部的差异，分植被类型和主要树种（组）评价陕西省退耕地还林的固碳释氧量和经济价值。结果表明：1）陕西省退耕还地林年生物量生产力591.67×104 t，年固碳量263.67×104 t，年释氧量705.90×104 t，年固碳经济价值34.27×108 元，释氧经济价值56.48×108元。2）从退耕地还林目前均处于中幼林的实际考虑，采用生物量与林分材积平均比值法修正其单位面积的生物生产力，可以较客观地计量其固碳释氧量。3）退耕还林工程包括退耕地还林和配套荒山造林两部分，要全面评价工程固碳释氧功能，还应根据统计学原理，在抽样调查配套荒山造林面积保存情况和成林情况的基础上进行深入研究。
Abstract:
 According to the results of the acceptance of the conversing farmland to forest project,and the difference between southern and northern Shaanxi,the quantities of carbon fixation and oxygen release and relative economic values were evaluated based on the vegetation types and the main groups of the tree species.1)The amount of annual biomass production in Shaanxi was about 591.67×104 t ,annual carbon fixation: 263.00×104 t with an economic value of 34.27×108 yuan,and annual oxygen release:704.09×104t with an economic value of 56.48×108 yuan, 2)Because all trees were their in youth and middle ages in the project,it was objective to estimate the quantity of carbon fixation and oxygen release by correcting the biomass production with the ratio of the biomass to stand volume.3)The project included two parts: barren mountain afforestation and farmland afforestation,it was suggested that in order to comprehensively evaluate the amounts of carbon fixation and oxygen release,sampling survey should be carried out by using statistical methods to understand the preserving and formation situations of afforestation in barren mountains.
