摘要
以昆嵛山国家级自然保护区森林生态系统为对象,探究2009-2024年间土地利用变化对整个森林生态系统碳储量的影响,本文基于第二次国土调查、2024年国土变更调查和2024年林草湿综合监测数据,森林碳储量采取生物量法计算,其他土地利用类型碳储量采用碳密度修正后测算。结果显示,近15年,耕地流出较大,面积为891.42 hm^(2),主要流向果园等农用地,“非粮化”问题凸出;未利用地(以裸岩石砾地为主)转出最多,主要流向乔木林地,面积为998.99 hm^(2),占转出总面积32.16%;碳储量增加31.39WT,乔木林地平均碳密度由108.75 t/hm^(2)提高到132.03 t/hm^(2),表明昆嵛山保护区建区以来,生态保护具有显著成效,林地面积扩大,森林质量显著提高,碳储量随之呈超等比例方式加大。
Focusing on the forest ecosystem of the Kunyu Mountain National Nature Reserve,this study investigates the impact of land use changes on carbon storage across the entire forest ecosystem from 2009 to 2024.Based on data from the second national land survey,the 2024 national land change survey,and the 2024 comprehensive monitoring of forests,grasslands,and wetlands,the forest carbon storage is calculated using the biomass method,while other land use types'carbon storage is estimated after carbon density correction.The results showed that in the past 15 years,there hasd been a significant outflow of cultivated land,with an area of 891.42 hm^(2),mainly flowing towards agricultural land such as orchards,and the problem of"non grain conversion"has become prominent;unused land(mainly bare rock and gravel)hasd seen the most conversion,primarily to deciduous forest land,covering an area of 998.99 hm^(2),which accounts for 32.16%of the total converted area;carbon storage increased by 31.39WT,with the average carbon density in deciduous forest land rising from 108.75 t/hm^(2) to 132.03 t/hm^(2).This indicates that since the establishment of the Kunyu Mountain Reserve,ecological protection efforts have been highly effective,leading to an expansion in forested areas and a significant improvement in forest quality,resulting in a super-proportional increase in carbon storage.
