基于森林资源规划设计调查数据的森林碳储量估算分析--以镇沅县为例

An Estimation Analysis of Forest Carbon Reserve Based on Forest Resource Planning and Designing Data——An Example of Zhenyuan County

基于云南省普洱市镇沅县2016年第四轮森林资源规划设计调查数据,从不同森林类型、不同起源、不同龄组、优势树种、乡镇等方面,通过生物量扩展因子法,估算了镇沅县森林资源生物量、碳密度及碳储量。结果表明:第四轮森林资源规划设计调查中,镇沅县森林植被碳储量总量为1511.38×104 tC;不同森林类型中,阔叶林碳储量较针叶林高,占主导地位;不同起源中,天然林在森林植被碳储量中起到更大的作用;不同龄组中碳储量由高到低为中龄林、近熟林、成熟林、幼龄林、过熟林;优势树种(组)中,思茅松和栎类碳储量所占比例最大;各乡镇中,勐大镇碳储量最大,和平镇最小。

Based on the data of the forth round(2016)planning and designing of forest resource in Zhengyuan County,City of Pu’er,Yunnan Province,from the aspects of forest types,origins,age groups,dominant species and villages and towns,the biomass,carbon density and carbon reserve of forest resources in Zhengyuan County were estimated through biomass expansion factor method.The results show that,during the period of the forth forest resources planning and designing,the total carbon reserve of forest vegetation in Zhenyuan County is 1511.38×104 tC;from the viewpoint of forest types,the carbon reserve of broad-leaved forest,which takes a dominant position,is higher than that of coniferous forest;from the viewpoint of origins,natural forest plays a more importan role in carbon reserve;from the viewpoint of age groups,the carbon reserve that ranking from high to low is half-mature forest,near-mature forest,mature forest,young forest and over-mature forest;from the viewpoint of dominant species,the carbon reserve of Pinus khasys has larger proportion than Oak;from the viewpoint of villages and towns,the carbon reserve of Town of Mengda is the highest while Town of Heping is the lowest.
