本研究は、重慶市を事例に2000〜2020年の土地利用データとPLUSモデルを用いて、土地利用変化が炭素排出に与える影響を分析し、将来シナリオを予測した。結果、低炭素から高炭素への転換により正味排出量が大幅に増加し、生態保護シナリオでのみ排出削減が見込まれる。地域を4つのゾーンに分けた管理枠組みを提案している。
English
This study analyzes land use change impacts on carbon emissions in Chongqing (2000-2020) using the PLUS model and projects future scenarios. Net emissions soared from 13.19 to 52.73 million tons due to conversions to high-carbon uses. An ecological protection scenario reduces emissions, and a four-zone management framework is proposed for low-carbon transition.

📄 Abstract（原文）
As the world's second-largest carbon source after energy consumption， land use change profoundly affects terrestrial ecosystems and climate patterns. Understanding its carbon emission impacts is vital for achieving carbon reduction and neutrality goals. To this end， the mountainous megacity of Chongqing was selected as a case for investigation. Utilizing land use data from 2000-2020， an analysis employing the PLUS model was conducted to examine historical impacts and forecast future trends. Based on multi-scenario projections， spatially differentiated carbon reduction strategies are proposed. The results indicate： ① Between 2000 and 2020， Chongqing's landscape was dominated by cropland and forestland. Structural shifts involved decreases in cropland and grassland， while other land types expanded. Spatially， these changes were concentrated in the main urban core and the southeast， with less intensity in the northeast， a pattern projected to continue to 2030. ② Driven by the conversion of low-carbon to high-carbon land uses， net carbon emissions soared from 13.19 to 52.73 million tons from 2000 to 2020. Emission levels escalated across most districts， especially in the urban centers of Yubei， Jiulongpo， and Shapingba. Projections for 2030 indicate that land use change will increase emissions under the natural development and urban construction scenarios but decrease them under an ecological protection scenario. ③ A zoned management framework， dividing the region into four distinct zones-carbon reduction transition， emission reduction and sink enhancement， low-carbon development demonstration， and low-carbon advantage consolidation-offers a viable pathway toward a low-carbon transition in land use management.
