区域土地利用变化对植被碳汇的生态风险影响研究

Ecological Impact of Regional Land Use Change on Vegetation Carbon Sequestration

随着城镇化和工业化进程的快速推进,中国国土空间开发利用格局发生了剧烈变化,建设空间快速扩张,自然空间持续萎缩,农业空间明显重构,土地的利用格局出现了非常显著的变化。土地和植被处于一个生态链中,任何一方的变化都会引起另一方随之发生变化。植被碳汇是维护生态稳定的重要手段,而区域土地利用的变化在一定程度上会对植被碳汇造成一定的风险,从而影响生态平衡。本文首先对碳汇的基本内容进行了阐述,形成对碳汇的全面了解,并在此基础上分析了土地利用变化对植被碳汇的影响,最后以北部湾区域土地利用变化为例,详细探讨了区域土地利用变化对植被碳汇的生态风险影响,希望能够为今后相关内容的研究提供参考。

With the rapid advancement of urbanization and industrialization, China＇s land use space has undergone drastic changes in its pattern of space development and utilization. The construction space has expanded rapidly, natural space has continued to shrink, and agricultural space has reconstructed remarkably. Land use patterns have changed significantly. Land and vegetation are in an ecological chain, and any change in one side will cause the other side to change. Vegetation carbon sinks are an important means to maintain ecological stability, and changes in regional land use will, to a certain extent, cause certain risks to the carbon sinks in the vegetation, thus affecting the ecological balance. This article first elaborated the basic content of carbon sinks, formed a comprehensive understanding of carbon sinks, and analyzed the impact of land use changes on the vegetation carbon sinks on the basis of this. Finally, the land use change in the Beibu Gulf was taken as an example to discuss in detail. The impact of regional land-use change on the ecological risk of vegetation carbon sinks is hoped to provide a reference for the future research on relevant contents.
