辽宁西部沿海地区土壤碳库时空分布特征及其影响因素
|
摘要
沿海地区是海陆交互特殊地带,其土壤碳库变化对全球碳循环具有特殊意义。本文选择辽宁西部沿海多目标区域地球化学调查覆盖区作为研究重点,计算了区内土壤碳储量和碳密度,对其空间分布特征及近40年来土壤碳库变化状况和影响因素进行研究,旨在为该区今后土地利用规划、生态环境保护提供数据支撑。结果表明:研究区表、中、深层土壤碳密度空间分布规律基本一致,从20世纪80年代至今,表、中层土壤有机碳储量和碳密度总体均呈显著增加态势,表层土壤有机碳储量增加1.93 Mt,中层土壤有机碳储量增加9.88 Mt。其空间分布特征显示,高海拔、低温多雨有利于土壤有机碳的积累,降水增多、土壤酸化不利于土壤无机碳的积累。此外,土壤类型、土地利用类型、地貌类型和地质单元均与土壤碳密度显著相关,土地利用类型对土壤碳库影响最为深刻。
The change of soil carbon pool in coastal areas is of special significance to the global carbon cycle.Taking areas covered by the multi-purposes regional geochemical survey(MPRGS) in the western coast of Liaoning province as an example,the soil carbon reserve and density were calculated, and the spatial distribution characteristics, soil carbon pool changes in the past 40 years and influencing factors were studied also. It aims to provide data support for future land use planning and ecological environment protection. The results showed that the spatial distribution of carbon density are basically the same in top, middle and deep soil. Since the 1980 s, the organic carbon reserves and carbon density in the top and the middle soil have increased significantly. The organic carbon reserves in the top and the middle soil increased by 1.93 Mt and 9.88 Mt respectively. According to the analysis of the influencing factors, high altitude, low temperature and rainfall are conducive to the accumulation of soil organic carbon, while increased precipitation and soil acidification are not conducive to the accumulation of soil inorganic carbon. In addition, soil type, land use, geomorphic and geological unit are all significantly correlated with soil carbon density, among which land use has the most profound influence.
