英文摘要	BackgroundAssessment of carbon pools in semi-arid forests of India is crucial in order to develop a better action plan for management of such ecosystems under global climate change and rapid urbanization. This study, therefore, aims to assess the above- and belowground carbon storage potential of a semi-arid forest ecosystem of Delhi.MethodsFor the study, two forest sites were selected, i.e., north ridge (NRF)and central ridge(CRF). Aboveground tree biomass was estimated by using growing stock volume equations developed by Forest Survey of India and specific wood density. Understory biomass was determined by harvest sampling method. Belowground (root) biomass was determined by using a developed equation. For soil organic carbon (SOC), soil samples were collected at 0-10-cm and 10-20-cm depth and carbon content was estimated.ResultsThe present study estimated 90.51Mgha(-1) biomass and 63.49MgCha(-1) carbon in the semi-arid forest of Delhi, India. The lower diameter classes showed highest tree density, i.e., 240 and 328 individuals ha(-1) (11-20cm), basal area, i.e., 8.7 (31-40cm) and 6.08m(2)ha(-1) (11-20cm), and biomass, i.e., 24.25 and 23.57Mgha(-1) (11-20cm) in NRF and CRF, respectively. Furthermore, a significant contribution of biomass (7.8Mgha(-1)) in DBH class 81-90cm in NRF suggested the importance of mature trees in biomass and carbon storage. The forests were predominantly occupied by Prosopis juliflora (Sw.) DC which also showed the highest contribution to the (approximately 40%) tree biomass. Carbon allocation was maximum in aboveground (40-49%), followed by soil (29.93-37.7%), belowground or root (20-22%), and litter (0.27-0.59%).ConclusionOur study suggested plant biomass and soils are the potential pools of carbon storage in these forests. Furthermore, carbon storage in tree biomass was found to be mainly influenced by tree density, basal area, and species diversity. Trees belonging to lower DBH classes are the major carbon sinks in these forests. In the study, native trees contributed to the significant amount of carbon stored in their biomass and soils. The estimated data is important in framing forest management plans and strategies aimed at enhancing carbon sequestration potential of semi-arid forest ecosystems of India.
