基于生物量转换因子的林业剩余物理论资源潜力评估方法与应用

Theoretical Resources Potential Assessment Method of Forestry Residues and Its Application Based on Biomass Conversion Factor

林业剩余物资源潜力评估是资源有效开发和政府合理制定政策的基础。在林木生物量研究成果的基础上,提出了基于BCF的林业剩余物理论资源和能源潜力评估方法。利用该方法在安徽省黄山市黄山区进行了应用,评估了杉木、阔叶树、马尾松和毛竹4种林木林业剩余物理论资源和能源潜力,得出了2011-2013年黄山区林业剩余物总理论资源和能源潜力,2013年分树种和不同采伐方式林业剩余物理论资源和能源潜力以及剩余物产生率。为验证方法的准确性,在黄山区洋湖公益林场进行了杉木主伐、中龄林抚育标准样地、样木实测,通过与文献[1-3]和IPCC（2006）提供的方法和折算系数对比分析发现：根据文献[1-3]计算的杉木主伐和中龄林抚育剩余物理论资源潜力值分别比实测值高222.83%和134.97%;根据IPCC（2006）计算的理论值分别比实测值高47.62%和43.89%,本研究理论推算值仅分别比实测值高18.21%和27.10%,从一定程度上验证了方法的有效性。

Forestry residues resources potential assessment is the basic information for resource effectively development and rational policy made. According to the research on forest biomass,a method for assessing forestry residues resources is proposed based on BCF. Using this method,a case study on the forestry residues theoretical resources and energy potential of Cunninghamia lanceolata,Pinus massoniana,broadleaf wood and Bamboo has been done in Huangshan District,Anhui. The assessment obtained the total forestry residues theoretical resources and energy potential from 2011 to 2013,and the residues energy potential and production rate in different trees and different felling method in 2013 as well. In order to test the reliability,a field study on final felling,immature forest tending standard sample site,sample tree measured is conducted in Yanghu Forest Farm. Compared with methods and convert coefficient provided by literature [1-3]and IPCC（2006）,residues theoretical resource potential value of final felling and immature forest tending of Cunninghamia lanceolata forest are higher than control by 222. 83% and134. 97% respectively. The values based on IPCC（2006） are higher than control by 47. 62% and43. 89% respectively. In this study,Theoretical value is only 18. 21% and 27. 10% more than the actual measurement which verified effectiveness of the method in certain way.
