基于红外气相色谱监测的新增林地区域碳汇储量变化评估方法研究

Research on the Assessment Method of Carbon Sink Storage Change in Newly Added Forest Land Based on Infrared Gas Chromatography Monitoring

森林资源作为全球陆地生态系统的主体,是陆地表面最大的碳库,承担着全球温室气体调节和碳平衡的重要作用。森林通过同化作用吸收固定大气中的CO2,抑制其浓度上升的功能对于应对气候变化问题具有积极的现实意义。准确地估算林地区域尤其是新增林地的碳汇储量,对平衡区域碳收支及促进林业碳汇发展具有积极的现实意义。目前的碳储量监测方法主要基于地基观测、卫星遥感及大气碳循环模拟方法的等,单一观测方法均存在一定的局限性,现在越来越向“空天地”一体化相结合的方向发展,以获得更准确的森林碳汇储量评估值。针对新增林地面积,其对整体碳环境的宏观影响还相对较小,更多的则采用站点观测的方法进行其碳汇储量评估。本文着重介绍了基于红外气相色谱监测的方式进行新增林地面积的碳汇储量评估方法。

As the main body of the global terrestrial ecosystem, forest resources are the largest carbon pool on the land surface and play an important role in global greenhouse gas regulation and carbon balance. The function of forests to absorb and fix CO2 in the atmosphere through assimilation and inhibit the increase of its concentration has positive practical significance for coping with climate change. Accurately estimating the carbon storage of forest areas, especially newly-increased forest land, has positive and practical significance for balancing regional carbon budgets and promoting the development of forestry carbon sinks. The current carbon storage monitoring methods are mainly based on ground-based observations, satellite remote sensing, and atmospheric carbon cy-cle simulation methods. All single observation methods have certain limitations, and now the di-rection of the integration of multi-methods to obtain more accurate assessment values of forest carbon storage is widely accepted. For the newly-increased forest land area, its macroscopic impact on the overall carbon environment is relatively small;the method of site observation to evaluate their carbon storage is normally used herein. This paper focuses on the method of assessing the carbon storage of new forest land based on infrared gas chromatography monitoring.
