文章通过野外现场调查及室内分析实验可知:2003~2005年,桂林新寨地区花岗岩风化所致的碳汇分别为3.67×10g/a~8、3.99×10~8g/a及4.19×10~8g/a,而且CO_2汇具有不断增加的趋势。
Through the field investigation and laboratory analysis, we know that the carbon sinks caused by the weathering of granite in Xinzhai area of Guilin from 2003 to 2005 are 3.67 × 10-3 g / a, 3.99 × 10-8 g / a and 4.19 × 10-8 g, respectively / a, and CO 2 sink has a growing trend.
