通过2009年8月对新疆墨玉县人工减排林样地进行实地调查取样,获得该地区人工减排林生态系统植被生长状况各种数据,利用这些数据采用生物量与蓄积量关系为基础的植物碳储量估算方法及土壤剖面有机质百分含量推算土壤碳储量的方法分别对干旱区人工林植被、土壤碳储量进行估算。结果表明,干旱区墨玉县玉北固阻结合流沙固定技术试验示范区人工减排林现有碳储量4522.01Mg,波斯坦库勒天然稀疏植被封育区现有碳储量1840.12Mg,土壤平均碳储量相差不大,分别为25.91t/100m2和27.39t/100m2。波斯坦库勒天然稀疏植被封育区内大多是幼龄林,碳储量并未达到最大,随着树木的生长,这些林木还能够固定一定量的大气碳,波斯坦库勒天然稀疏植被封育区的生态系统碳储量能力还有很大的提升空间。新疆减排林区碳储量将进一步增加。
Through field survey and sampling of artificial emission reduction forest plots in Moyu County in Xinjiang in August 2009, various data on the vegetation growth status of artificial forest ecosystems in this region were obtained. Based on the relationship between biomass and stock volume, Plant carbon storage estimation method and soil organic matter percentage soil profile calculation of soil carbon storage method were estimated plantation in arid area plantation soil, soil carbon storage. The results showed that the available carbon reserves of artificial abatement forest in Yubei County of Mudao County in Mudao County combined with the fixed-flow experiment of sand-fixing technology were 4522.01Mg. The existing carbon storage of natural sparse vegetation enclosure in Postaincule was 1840.12Mg, Reserves are not much difference, respectively 25.91t / 100m2 and 27.39t / 100m2. Most of the sturdy natural sparse vegetation in Bostencule are young and have not reached their maximum level. With the growth of trees, these trees can also fix a certain amount of atmospheric carbon, and the natural sparse vegetation of Bostenculeu is sealed The region’s ecosystem carbon storage capacity there is still much room for improvement. Carbon emissions in Xinjiang’s reduced forest areas will further increase.
