| 摘 要： | 目的]造林作为一种土地利用变化,可以增加陆地碳汇,减缓大气中CO2的积累.以克拉玛依人工杨树碳汇林及原生荒漠灌木林为研究对象,分析人工造林对土壤碳储量的影响.方法]通过合理的样方设置分别于林区和荒漠灌木林区进行土壤分层取样,并采用重铬酸钾容量法对碳汇林下及原生荒漠植被下土壤有机碳储量进行了估算和分析.结果]原生荒漠植被条件下土壤平均碳密度仅为0.3 ～0.6 kg/m2,而建造碳汇林后,该区域土壤平均碳密度有大幅提高,为0.47 ～1.44 kg/m2;土壤有机碳含量随土体深度的加深而减少;碳汇林对土壤有机碳储量的提高在浅层土壤中表现得更为明显.结论]克拉玛依人工杨树碳汇林有效地提升了土壤有机碳储量,对改善当地土壤环境质量有明显的作用.

| Abstract: | Afforestation as a land-use change can increase the terrestrial carbon sink and alleviate atmospheric CO2 increment.【Objective】In this paper,Karamay carbon sink forest and the protogenesis hungriness shrubbery were chosen as the research object,and the influence carbon sink forest acting on soil organic carbon was analyzed.【Method】After obtaining layered soil sample through reasonably setting quadrat,soil organic carbon of carbon sink forest and protogenesis hungriness shrubbery applying potassium dichromate titration were estimated and analyzed.【Result】Through measurement,we found the carbon intensity of protogenesis hungriness shrubbery was 0.3-0.6 kg/m2,and after afforestation,the carbon intensity was 0.47-1.44 kg/m2.【Conclusion】The results showed that: 1)The construction of forest carbon sinks in Karamay can effectively enhance the soil organic carbon storage;2)the soil organic carbon content was decreasing with soil deepening;3)carbon sink forest on soil organic carbon increased in the shallow soil.The construction of the Poplar Plantation carbon sink forest in Karamay could significantly enhance soil organic carbon storage,improve the ecological fragility of the environment and play a significant role in the quality of the soil. |
