摘要：根据新疆第二次森林资源普查的结果统计甘家湖保护区不同盖度梭梭林的面积。选择3个不同盖度的梭梭林测定梭梭、草本植物以及土壤的有机碳含量,计算梭梭林的总碳储量。结果表明:甘家湖保护区的梭梭林总面积为360.79km^2,98.43%的梭梭林盖度低于50%。甘家湖保护区梭梭林的总碳储量达到2.66万t。低盖度梭梭林的碳储量占总碳储量的97.67%。土壤和梭梭的碳储量分别占总碳储量的71.42%和23.69%。盖度影响梭梭林的梭梭根系和全株生物量以及草本植物生物量。高盖度梭梭林的梭梭生物量最高,中盖度梭梭林的草本植物生物量最高。盖度影响梭梭根系含碳量。低盖度梭梭林根系含碳量显著高于中盖度。盖度和深度影响土壤碳密度。高盖度梭梭林的土壤碳密度最高。20cm以下土壤碳密度高于表层。梭梭单株碳储量与枝条、根系和单株的干重呈显著正相关。土壤碳密度与土壤有机碳含量呈显著正相关。今后应该采取措施促进梭梭林生长,提高其碳储量。
The result of the Second Forest Resource Survey of Xinjiang was used to evaluate total area of H. ammodendron forests. The H. ammodendron forests were divided into three coverages to measure carbon storage,herbaceous plants and soil carbon storage. The results showed that total area of H. ammdendron forests in Ganjiahu Reserve was 360. 79km2. The H. ammdendron forests that the coverages were lower than 50% accounted for98. 43% of the total forests. Total carbon storage of H. ammodendron forests in Ganjiahu Reserve was 2. 66 ×105t. Low coverage H. ammodendron forests accounted for 97. 67% of total carbon storage. Soil and H. ammodendron accounted for 71. 42% and 23. 69% total carbon storage,respectively. Root and plant biomasses of H.ammodendron and herbaceous biomass were affected significantly by coverage. The biomasses of root and plant was the highest in higher coverage of H. ammdendron forests,whereas herbaceous biomass was the highest in H.ammdendron forests with middle coverage. Carbon content of H. ammodendron root was affected significantly by coverage. Carbon content of low coverage of H. ammodendron forests was higher than middle coverage. Soil carbon density was affected significantly by coverage and depth. Soil carbon density was the highest in H. ammdendron forests with high coverage. Soil carbon density was higher in soil layers deeper than 20 cm. Plant carbon stock of H. ammodendron was significantly positively related with dry mass of shoot,root and total plant. Soil carbon density was significantly positively related with soil organic carbon content. The growth of H. ammodendron forests should be promoted and its carbon storage will be enhanced in future.
