This study investigated the effect of land use land cover (LULC) changes on carbon sequestration in the Hayat-ul-Mir subtropical scrub reserve forest, Pakistan. Supervised maximum likelihood classification of Landsat satellite imagery was done to assess spatio-temporal changes in LULC during 2007, 2013 and 2019. The CA-Markov model was used to simulate LULC of 2030. Spatial LULC data and carbon pools data was processed in Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) carbon model to investigate the effect of LULC on future carbon dynamics. The analysis revealed increase in cover of A. modesta and O. ferruginea and decrease in agriculture, built up and barren area of forest during 2007-2019 and 2030. The analysis also showed that the forest would additionally sequester 111 Mg C with an overall Net Present Value of $4112.05 in year 2030. The analysis revealed LULC changes on 25% area with increase and decrease in the value of ecosystem service (at some location) from carbon storage and loss as CO emissions respectively depending on the type of LULC converted. The study is helpful in identifying areas of potential carbon sequestration to maximize net benefits from management interventions.
本研究调查了土地利用/土地覆盖(LULC)变化对巴基斯坦海亚特-米尔亚热带灌丛保护区碳固存的影响。通过监督最大似然分类对 Landsat 卫星图像进行了评估,以评估 2007 年、2013 年和 2019 年期间 LULC 的时空变化。CA-Markov 模型用于模拟 2030 年的 LULC。通过综合生态系统服务和权衡的评估(InVEST)碳模型处理空间 LULC 数据和碳储量数据,以调查 LULC 对未来碳动态的影响。分析表明,在 2007-2019 年和 2030 年期间,A. modesta 和 O. ferruginea 的覆盖面积增加,农业、建成区和森林荒地减少。分析还表明,到 2030 年,森林将额外固存 111 Mg C,净现值总额为 4112.05 美元。分析表明,在 25%的区域内,由于 LULC 转换的类型不同,碳储存和 CO 排放损失(在某些地点)导致生态系统服务价值(增加和减少)发生变化。该研究有助于确定潜在的碳固存区域,以从管理干预中获得最大的净收益。
