中文摘要:
      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。
英文摘要:
      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 8 years. The results showed that the variation of carbon content in different organs was 41.01%~47.35% under the treatment of contour reverse-slope terrace, the average carbon content was ranked as sti > 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% and 35.71%) 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.
