摘要
对鲁西黄泛平原典型地区菏泽市的杨树人工林碳储量及碳贮库特征进行了研究。结果表明:林木碳密度为39.67 t/hm2,土壤碳密度为34.21 t/hm2;4、5、6、7、9年生杨树林林木碳密度分别为28.54、34.45、36.51、41.24、44.80 t/hm2,当地森林固碳增汇主体为3～9年生杨树幼龄林。国有林场杨树林地总碳储量为0.321 Tg,碳密度为74.74 t/hm2,其中曹县青崮集林场最大;植被和土壤碳储量分别为0.174和0.147 Tg,林木碳储量占植被总碳储量的97.9%。杨树各品种固碳能力为中菏1号>中菏2号>107>I-69,中菏1号、2号和107为目前当地杨树人工林固碳增汇的首选品种。菏泽市杨树人工林是山东省森林碳汇重要的碳贮库,固碳增汇潜力巨大,建议适当延长轮伐期。
The research was conducted to investigate the carbon stocks and carbon storage of poplar plantations based on poplar plantations in Heze, which was the typical district of the plain formly flooded by the Yellow River in western Shandong Province, China. The results show that the carbon density of poplars is 39.67 t/hm2, and the soil carbon density is 34.21 t/ hm2. Carbon density of 4, 5, 6, 7 and 9 year-old poplar plantations are 28.54, 34.45, 36.51,41.24 and 44.80 t/hm2, respectively. The young forest of 3-9 year-old are the main part of carbon sequestration in Heze. The carbon storage of state-owned poplar plantations is 0.321 Tg, and the carbon density is 74.74 t/hm2. Among them, the carbon storage of state-owned forest at Cao County ranks the first place. The vegetation and soil carbon storage are O. 174 and 0. 147 Tg. Poplars＇ carbon storage accounts for 97.9% of vegetation＇ s. The order of carbon density with different varieties of the same age is： Zhonghe NO. 1〉 Zhonghe NO. 2 〉107〉 1-69. Zhonghe NO. 1, NO. 2 and 107 are the preferred varieties of carbon sequestration. Therefore, the poplar plantations in Heze are the significant part of forest carbon sequestration in Shandong Province, China. Extending the rotation properly was suggested.
