[0002] Selection of tree varieties for forest planting refers to the process of selecting the most suitable tree varieties or species for planting in a region according to multiple factors such as specific environmental conditions, market demand, economic benefits and ecological goals during the process of forest planting. At present, with the global attention to environmental protection and sustainable development, forestry, as an indispensable part of the ecosystem, its sustainable development is particularly important. With the continuous development of information technology, forestry informatization and intelligence have also become a convenient way in the process of selection of tree varieties for forest planting. The selection method of tree varieties for forest planting based on big data has also emerged. It uses massive data and advanced analysis technology to optimize the process of selecting tree varieties for forest planting. For example, for the three trees of poplar, willow and catalpa, growth rate, stress resistance, wood quality and ecological adaptability are important quantitative traits for selection. Through big data analysis technology, the performance of different varieties in these aspects can be evaluated more scientifically. At the same time, in order to further improve the efficiency of forest planting, the use of big data for selection of tree varieties for forest planting will be more widely used and developed.
[0003] In the existing technology, since different tree species and trees for different purposes have different evaluation standards, there will be certain errors in the selection prediction results. Therefore, it is our problem to establish a unified evaluation mechanism to improve the evaluation accuracy and the accuracy of the prediction results.

Features related to tree species in the data set are extracted, including uses and key traits, such as growth rate, adaptability, economic value, and ecological benefits. Statistical methods are used to screen out key features that affect tree species.
