| 摘 要： | 通过对退耕还林林地上生物量的监测，退耕还林6年的乔木型、乔草型、经济林型、荒山造林封禁区典型林地上生物量分别为26043、6575、18790、2980kg／hm^2。在生物量研究的基础上，根据光合作用制造有机物与固碳释氧之间的关系，初步研究了退耕还林林地上固碳释氧总效益为22916．4万元，从而科学客观地评估了退耕还林工程在固碳释氧方面的效益，为退耕还林效益监测、工程总体效益评估、生物固碳的研究提供基础数据和方法依据。

| Abstract: | Through conversion of cropland to forests monitoring about biomass, conversion of cropland to forests for six years ,biomass of arbor type ,arbor-herb type, economic forest and afforestation in the forbidden region were 26 043.6 575.18 790.2 980 kg/hm^2 respectively. On the base of the research of the biomass ,according to the relationship between organic compounds and carbon fixation and oxygen release photosynthesis, preliminary study was carried out on the total effects of carbon fixation and oxygen release conversion of cropland to forests in six years were 276.186 million, therefore , scientific and objective assessment of the effects of carbon fixation and oxygen release conversion of cropland to forests project, which provide basic data and methods for monitoring the effects of conversion of cropland to forests, total effects of projects, research of carbon fixation. |
