摘要

了解巴西本土木材市场有助于森林管理者并指导保护政策。本研究旨在评估巴西原生木材(木炭、圆木、柴火和锯材)四种产品的供需时空分布。我们使用了米纳斯吉拉斯州(MG) 2006年至2016年消耗的木材量,追踪其在巴西的供应商,占3100万立方米。这些数据被用作计算平均中心和进行分组分析的输入。巴西能源部门的木材供应中心已经从塞拉多转移到卡廷加生物群落。这种变化与巴西农业扩张的历史模式是一致的。最大的木材生产地区是:南马托格罗索州东部,Goiás州南部和巴伊亚州中南部。实木供应中心已经从北部转移到中西部地区,但几乎所有年份都留在亚马逊生物群系内。这种模式很可能是亚马逊地区木材管理实践的结果。马德拉-瓜波尔和Rondônia州东部、帕尔州东南部和东北部以及马托格罗索州北部是MG最重要的实木供应地。木材能源消耗主要集中在MG州的中部和北部地区,特别是在Sete Lagoas,生铁和水泥工业的中心。实木产品分散在MG州,包括贝洛奥里藏特、Conselheiro Lafaiete、ub和uberl印度,这些都是MG家具行业的本地木材配送中心。空间统计数据有助于开发巴西本土木材市场的活动,并为决策者提供了以前无法获得的重要信息。

UNDERSTANDING THE DYNAMICS OF THE BRAZILIAN MARKET FOR NATIVE FOREST WOOD: A CASE STUDY FOR MINAS GERAIS STATE, BRAZIL
ABSTRACT Understanding the Brazilian market for native wood helps forest managers and can guide conservation policies. This study aimed to evaluate the spatial and temporal distribution of supply and demand of the Brazilian native wood for four products namely, charcoal, roundwood, firewood, and sawn wood. We used the consumed wood volume from 2006 to 2016 in Minas Gerais (MG) tracking its supplier in Brazil accounting for 31 million cubic meters. These data were used as input for calculating mean centers and performing grouping analysis. The wood supply centers for the energy sector in Brazil have moved from Cerrado to the Caatinga biome. This change is consistent with historical patterns of agricultural expansion in Brazil. The largest mesoregions producing wood were: East of Mato Grosso do Sul State, South of Goiás State, and Center-South of Bahia State. The solid wood supply centers have moved from the North to Midwest regions but remained within the Amazon biome for almost all the years. This pattern is likely a consequence of timber regulation practices in the Amazon. The mesoregions: Madeira-Guaporé and East of Rondônia State, Southeast and Northeast of Pará State, and North of Mato Grosso State were the most important suppliers of solid wood to MG. Wood consumption for energy is centered in the Center and North regions of MG State, especially in Sete Lagoas, a hub of pig iron and cement industries. Solid wood products are dispersed in MG State, being Belo Horizonte, Conselheiro Lafaiete, Ubá, and Uberlândia the distribution centers of native wood for the furniture industry within MG. The spatial statistics helped to exploit the activity of the native wood market in Brazil and provides essential information for decision-makers that was not previously available.
