摘要

碳排放导致的全球变暖威胁着地球上的生命。根据世界气象组织的数据,地球温度比工业化前水平(1850-1900 年)上升了 1.06°C 至 1.26°C。根据政府间气候变化专门委员会的报告(2021 年),气候变化的影响将无一例外地波及世界所有地区。印度尼西亚承诺在 2030 年前通过自身努力减少 29% 的碳排放量,通过国际合作减少 41% 的碳排放量。土地覆被分析采用无监督分类法,地表以上碳排放量计算方法采用 IPCC 方法,即存量差分法,泥炭分解排放量分析方法采用 Hooijer 公式等人(2006 年,2010 年),根据 TMAT BRGM 数据估计的水位与 NDWI Landsat 8 数值回归方程,然后将地表以上和地表以下排放量相加得出碳排放总量。根据研究地点的土地覆盖分析结果,该地区以种植园为主,占 37.8%,而森林面积仅占 7.9%。KHG Sungai Mendahara - Batanghari 地区的碳排放量呈图形波动,有增有减,但直到 2022 年都呈上升趋势。

Analisis Emisi Karbon di Kesatuan Hidrologi Gambut Sungai Mendahara - Sungai Batanghari
Global Warming Due to Carbon Emissions is a threat to life on earth. According to the World Meteorological Organization, the earth's temperature rose by 1.06 °C to 1.26 °C above pre-industrial levels (1850–1900). According to the IPCC report (2021), the impacts of climate change will reach all regions in the world without exception. Indonesia's commitment to reduce carbon emissions by 29% with its efforts and 41% with international cooperation until 2030. Analysis of land cover uses the Unsupervised Classification, the method for calculating carbon emissions above the surface uses the IPCC method, namely the stock differential and the method for analyzing emissions of peat decomposition uses the Hooijer formula et al. (2006, 2010) with estimated water level from the TMAT BRGM data regression equation with NDWI Landsat 8 values then total carbon emissions by adding emissions from above and below the surface. Based on the results of the analysis of land cover at the research location, the area was dominated by plantations at 37.8%, while the forest area was only 7.9%. Ground carbon emissions average 0.23 Mt CO2-eq per year, below Ground carbon emissions are 9.94 Mt CO2-eq and total carbon emissions are 10.17 Mt CO2-eq with total emissions from 2013 - 2022 of 91.6 Mt CO2-eq Carbon emissions in KHG Sungai Mendahara - Batanghari graphically fluctuate, there is an increase and decrease but tends to increase until 2022 this is due to land conversion and massive land clearing in forest areas and the biggest contributor to carbon emissions from decomposition peatlands.
