在考虑可持续性方面的限制，本文回顾了一种方法的发展，以评估在墨西哥引进的生物能源供应链的基础上，森林木本生物质。三个研究单元包括对森林生物量利用残留物的分析，这些残留物来自：（1）采伐活动，（2）未采伐的林分和（3）锯木厂。一个区域的案例研究，重点是在10个省的商业重要性树种（松树，橡树和冷杉）的木材产量最高的位于北部和中南部的国家的一部分，进行了分析。在应用该方法后，可供能源使用的木质生物质的理论潜力为6 357 482立方米。在适用可持续性限制因素时，技术上可行的森林木质生物质能源供应总量为5，798，722立方米，相当于2013年45.96 PJ的技术能源潜力。此外，生物质能源流程图显示每个分析的来源和物种的能量值。蒙特卡洛模拟进行了利用所产生的可用的木质生物质的能源使用所涉及的每一个成本。在缺乏包括森林作业和生物能源转化在内的国家研究以计算可持续能源潜力的情况下，所制定的方法增加了评估木本生物质可用性的创新。
While considering constraints in regard to sustainability, this paper reviews the development of a methodology to assess the introduction of bioenergy supply chains in Mexico based on forest woody biomass. Three research modules include analyses of forest biomass utilization residues that originated from: (1) harvesting activities, (2) non-extracted stands and (3) sawmills. A regional case study focusing on tree species of commercial importance (pine, oak and fir) in the 10 provinces with the highest timber production located in the north and central-south part of the country, is analyzed. After applying the methodology, the theoretical potential of available woody biomass for energetic use amounts to 6,357,482 m3. When applying the sustainability constraints, the technically feasible supply of forest woody biomass for energetic use sums up to 5,798,722 m3, which relate to a technical energy potential of 45.96 PJ for 2013. Moreover, a biomass energy flow chart showing energy values for each analyzed source and species is presented. Monte Carlo simulations were carried out for each cost involved in utilizing the resulting available woody biomass for energetic use. In the absence of national studies which include forest operations and bioenergy transformation to calculate the sustainable energy potential, the developed methodology adds innovation for assessing woody biomass availability.
