库尔勒香梨经济林生物量与碳储量及空间分布

Biomass and Carbon Storage and Their Spatial Distribution of Economic Forest With Korla Fragrant Pear

以2015年库尔勒市森林资源二类调查数据,提取的库尔勒分布面积最大的库尔勒香梨经济林生态系统为研究对象,采用平均生物量法测算了库尔勒香梨的生物量和碳储量,研究了库尔勒香梨经济林种植对当地碳储量的影响,以期对新疆人工林森林碳储量进行分析。结果表明:库尔勒市经济林生态系统碳密度不高,固碳潜力大。2015年库尔勒香梨生物量和碳储量分别为53.94万t和26.97万t,库尔勒香梨碳储量占经济林总碳储量的92.25%;在空间分布上,阿瓦提乡的库尔勒香梨经济林生物量和碳储量最高,分别为11.88万t和5.94万t,经济牧场库尔勒香梨经济林生物量和碳储量最低,分别为0.04万t和0.02万t。

The biomass and carbon storage of Korla fragrant pear were calculated based on the Korla fragrant pear economic forest ecosystem with the largest Korla fragrant pear distribution area.The biomass and carbon storage of Korla fragrant pear were estimated by mean biomass method.The results showed that the carbon density of economic forest ecosystem was low and the potential of carbon sequestration was high in Kuerle city.In 2015,Korla fragrant pear biomass and carbon storage were 53.94×10^4 t and 26.97×10^4 t,respectively,and Korla fragrant pear storage accounted for92.25% of total carbon storage.In the spatial distribution,the biomass and carbon storage of Korlafragrant pear economic forest in Awati township had the highest storage which were 11.88×10~4 t and 5.94×10~4 t,respectively.The economic biomass and carbon storage of Korla fragrant pear economic forest in the economic pasture had the lowest storage,which were 0.04×10^4 t and 0.02×10^4 t,respectively.
