以土壤有机碳（SOC）和树木生物量形式储存的碳通常是森林中最高的碳库，并受到退化和森林砍伐的影响。不同高度的“C”储量对气候变化的影响可能对“C”汇的保护和管理产生重要影响。本研究在印度北阿坎德邦特哈里加尔瓦尔的亚热带地区，研究了低海拔（海拔790 ~ 824 m）、中海拔（海拔825 ~ 960 m）和高海拔（海拔1168 ~ 1212 m） 3个海拔高度的黑松（anogeissus latifoliatree）的碳储存潜力及其土壤特性，为维持生命提供燃料、饲料和小木材。研究结果表明，土壤水分和pH值随深度和海拔的增加而增加，土壤有机碳和土壤氮呈相反的趋势。容重（BD）不具有任何变化趋势，在960 m前随着土层深度和海拔的增加而增加，随着海拔的增加而进一步减小。据报道，与UA和LA相比，MA的树木密度、生物量和碳储量最高，因为森林茂密，树径更大。从土壤碳储量、氮素、碳氮比（C/N: < 10）和支持微生物降解的气候驱动因素等方面分析得出：在区域和全球层面上，阔叶林在碳减排和减缓气候变化方面发挥了重要作用。该研究将有助于环保人士、林业工作者和政策制定者在区域和全球范围内激发森林物种退化对气候变化和社会经济发展的综合影响。
The carbon stored as soil organic carbon (SOC) and tree biomass is typically the highest carbon pool of the forest and is impacted by degradation and deforestation. The impact of "C" stocks on climate change at different altitudes can have vital implications for the conservation and management of "C" sinks. This study was undertaken in subtropical belt of Tehri Garhwal, Uttarakhand, India, to understand the carbon-storing potential ofAnogeissus latifoliatree and its soil properties in three altitudes, i.e., lower (LA: 790-824 m), middle (MA: 825-960 m), and upper (UA: 1168-1212 m), which provide fuel, fodder, and small timber for life support purposes. Results of the study suggested that soil moisture and pH increase with increasing depth and altitude, whereas SOC and soil nitrogen show reverse patterns. Moreover, bulk density (BD) does not follow any trend (i.e., BD increases with soil depth and altitude until 960 m and further decreases with an increase in altitude). Tree density, biomass, and carbon stock reported highest in MA compared with UA and LA because of dense forest and greater tree diameter. Looking into the soil carbon stock, nitrogen, C/N ratio (C/N: < 10), and climatic drivers supportive to microbial degradation, it is concluded thatA. latifoliaforest has played an important role in carbon reduction and mitigating climate change at regional and global levels. The study will help environmentalists, foresters, and policy-makers to stimulate the combined effect of degradation of forest species on climate change and socioeconomic development at regional and global scale.
