摘要

【目的】土地利用/覆被变化通过改变陆地植被覆盖度对生态系统产生影响,笔者估算1990—2015年三峡库区不同土地利用类型碳储量的变化,及时有效地评估土地利用变化与区域生态系统碳储量的关系,了解三峡库区生态系统碳储量对土地利用变化的响应,为区域碳循环研究提供参考。【方法】以1990年、2000年、2015年Landsat影像获取三峡库区土地利用/覆被变化数据,应用InVEST模型定量分析了土地利用/覆被变化对三峡库区生态系统碳储量的影响。【结果】1990—2015年三峡库区土地利用格局和各类土地面积发生了明显变化,林地、水域、建设用地和未利用地面积均不断增加,而耕地和草地面积减少; 1990—2015年三峡库区生态系统碳储量呈持续增加趋势,净增加量为90.43 Tg,增加率为24.47%,年增加率为0.98%; 三峡库区生态系统碳储量空间分布不均,呈现出东高西低、南高北低的趋势; 耕地转化为林地是库区生态系统碳储量增加的主要原因,碳损失途径主要源于林地开垦为耕地、其他土地利用类型转为水域和建设用地。【结论】三峡库区土地利用类型变化导致生态系统碳储量时空分布格局发生了相应变化,生态系统碳储量随林地面积的增加而增加。因此,在保障耕地安全的前提下,加大三峡库区退耕还林力度,加强三峡库区林地保护,有助于增加库区碳汇潜力并改善库区生态环境。

Abstract

Abstract: 【Objective】Changes in carbon storage for different land use types in the Three Gorges Reservoir Area(TGRA)during 1990—2015 were estimated to understand the response of ecosystem carbon storage to land use changes in the TGRA, and provide reference for the study of the regional carbon cycle.【Method】Land use/cover change data in the TGRA were obtained from Landsat images from 1990, 2000 and 2015, and effects of land use/cover change on carbon storage in the TGRA were quantitatively analyzed using the InVEST model.【Result】 From 1990 to 2015, land use pattern and area clearly changed in the TGRA. Woodland, water bodies, construction land, and unused land increased in area, while farmland and grassland decreased in area. The total amount of carbon storage showed an increasing trend in the TGRA from 1990 to 2015, with a net increase of 90.43 Tg C, an increase rate of 24.47%, and an annual increase rate of 0.98%. Carbon storage was heterogeneous in space, being high in the east and the south, and low in the west and the north. Conversion of farmland to woodland was the main factor affecting the increase in carbon storage in the TGRA, whereas the loss of carbon storage was mainly caused by conversion of woodland to farmland and other land use types to water bodies and construction land. 【Conclusion】Land use changes in the TGRA have led to corresponding changes in the spatial and temporal distribution pattern of ecosystem carbon stocks, carbon stocks have increased with increase in woodland area. Therefore, under the precondition of ensuring the safety of farmlands, TGRA should intensify the implementation of returning farmlands to forests, and strengthen the protection of woodlands to increase the regional carbon sink potential and improve the regional ecological environment.
