In state of Rio de Janeiro, the Southeast Region of Brazil, 97.91% of the reforested areas contain exclusively species of Pinus and Eucalyptus. Due to the growing demand for raw forest materials, and low diversity of planted species, the market needs to explore new ones. Paricá (Schizolobium amazonicum Huber ex Ducke), Brazilian firetree (Schizolobium parahyba), Cedar (Toona ciliate), and Teak (Tectona grandis) are species with high economic value and are already found in small reforestation areas in the state of Rio de Janeiro. The goal of this study was to find the suitable environmental areas to good productivity each of these four forest species in the State of Rio de Janeiro. Suitable environmental areas were determined by classifying climate maps (water deficit, rainfall, and air temperature) and digital elevation models (DEM) of the State of Rio de Janeiro, based on the climatic and altitude demands of each species. Maps of suitable areas were generated using spatial analysis as raster map algebra and raster map reclassification. The species under study showed great potential for growth throughout the State of Rio de Janeiro. Brazilian firetree (known as Guapuruvu in Brazil) presented the largest environmentally suitable area for planting in the state (47%), especially in regions of low maximum rainfall, associated with high temperatures and low altitudes in Rio de Janeiro (e.g., Baixadas Litorâneas with 36.9% of suitable area). Paricá presented the smallest environmentally suitable area (19%), with suitable areas in regions of altitude less than 700 m (e.g., Médio Paraíba and Serrana, within 27.4% and 20.8% of the suitability area, respectively.). Future studies could refine the suitable areas by examining the soil conditions of each area and researching the economic and social factors that are unique to each region.

巴西东南部里约热内卢州适合商业木材的环境区域

在巴西东南地区的里约热内卢州，97.91% 的重新造林区域仅包含松树和桉树物种。由于对原始森林材料的需求不断增长，而种植物种的多样性较低，市场需要探索新的品种。Paricá (Schizolobium amazonicum Huber ex Ducke)、巴西火树 (Schizolobium parahyba)、雪松 (Toona ciliate) 和柚木 (Tectona grandis) 是具有很高经济价值的物种，已经在里约热内卢州的小型重新造林区发现。这项研究的目标是在里约热内卢州为这四种森林物种中的每一种找到合适的环境区域，以实现良好的生产力。通过对气候图（缺水、降雨、和气温）和里约热内卢州的数字高程模型 (DEM)，基于每个物种的气候和海拔需求。使用空间分析作为栅格地图代数和栅格地图重分类生成合适区域的地图。所研究的物种在整个里约热内卢州都显示出巨大的增长潜力。巴西火树（在巴西被称为 Guapuruvu）是该州最大的环境适宜种植区（47%），特别是在最大降雨量低的地区，与里约热内卢的高温和低海拔地区（例如，Baixadas Litorâneas）适用面积的 36.9%）。Paricá 提出了最小的环境适宜区域 (19%)，在海拔低于 700 m 的地区（例如，Médio Paraíba 和 Serrana，在 27.4% 和 20 以内）的适宜区域。8% 的适用面积。）。未来的研究可以通过检查每个区域的土壤条件和研究每个区域特有的经济和社会因素来细化合适的区域。
