等高反坡阶对滇中云南松林乔木层碳储量及碳增量分配格局的影响
|
摘要
通过标准地调查和生物量实测相结合的方法,对布设等高反坡阶后滇中云南松林乔木层碳含量、生物量、碳储量及分配特征进行了估算,并分析了8年后各器官碳增量及分配格局特征。结果表明:布设等高反坡阶后云南松各器官碳含量变幅为41.01%～47.35%,平均碳含量高低排列依次为干>叶>枝>皮>粗根>中根>细根。10～15龄的云南松林在布设等高反坡阶后地上部分总生物量比对照高32.75%,等高反坡阶显著提高了10～15龄和15～30龄地下部分生物量(30.73%和35.71%),总生物量随着龄组的增加而显著增加。等高反坡阶显著提高了10～15龄云南松林地上部分碳储量(32.79%)和15～30龄地下部分碳储量(35.60%);布设等高反坡阶8年后显著增加了10～15龄、15～30龄地上部分碳增量(53.33%和20.45%)和地下部分碳增量(53.70%和73.43%)。综上,人工造林时应对等高反坡阶予以高度关注,适度发展等高反坡阶措施,在等高反坡阶基础上因地制宜地进行人工造林,增加山地造林面积和植被碳储量,从而保护当地生态环境。
Carbon content,biomass,carbon storage and distribution pattern in tree layer of Pinus yunnanensis forest with contour reverse-slope terrace arrangement were estimated in central Yunnan through standard plot survey and biomass measurement,and characteristics of carbon increment and distribution in each organ were analyzed in 8years.The results showed that the variation of carbon content in different organs was41.01% ～47.35% under the treatment of contour reverse-slope terrace,the average carbon content was ranked as stem>leaf> branch> bark>thick root> median root>fine root.Aboveground biomass of the 10～15-year-old plantation was 32.75%higher under the treatment of contour reverse-slope terrace than that of control.Belowground biomass of the 10～15-year-old and 15～30-year-old plantation(30.73%and35.71%)were increased significantly under contour reverse-slope terrace,and the total biomass raised significantly with the increasing of age group.Carbon storage of aboveground in 10～15-year-old(32.79%)and carbon storage of belowground in the 15～30-year-old(35.60%)were significantly increased under contour reverse-slope terrace.After 8 years of arranging contour reverse-slope terrace,carbon increment of aboveground(53.33%and 20.45%)and carbon increment of belowground(53.70%and 73.43%)increased significantly in 10 ～ 15-year-old and 15 ～ 30-year-old plantation.In conclusion,contour reverse-slope terrace should be pay close attention in the process of afforestation.Artificial afforestation should be carried out in accordance with local conditions on the basis of contour reverse-slope terrace to increase the afforestation area and vegetation carbon storage in slope areas so as to protect the local ecological environment.
