重庆市渝北区森林碳汇量估算研究

碳汇一般是指从空气中清除二氧化碳的过程、活动、机制。在林业中主要是指植物吸收大气中的二氧化碳并将其固定在植被或土壤中，从而减少该气体在大气中的浓度。重庆市渝北区作为国家级开发区“两江新区”的重要组成部分，对区域内的森林碳汇量进行估算将提供重要参考与实践意义，本文应用目前比较成熟的森林碳汇量计算方法，在计算出森林生物量的基础上，针对渝北全区进行了碳汇量的计算。结果表明：碳汇总量已达到724301．01963t。

Estimation of the Amount of Forest Carbon Sinks in Yubei District of Chongqing City

Carbon Sequestration generally refers to the process, activity and mechanism of removing carbon dioxide from the air. In forestry, it mainly refers to the plants to absorb carbon dioxide in the atmosphere and fix it in vegetation or soil, thereby reducing the concentration of this gas in the atmosphere. Yubei District of Chongqing is a significant part of the ＂New Two River Districts＂ which is the national develop- ment zone. Therefore, it would provide valuable reference and practice to estimate the amount of forest carbon sequestration in this region. In this paper, currently more useful carbon sequestration calculation method is used to calculate the carbon sequestration of whole region on the basis of known forest biomass. The results have shown that the total quantity of carbon sequestration has reached 724 301. 019 63 t.
