摘要
文章通过收集和整合相关的地理、气候和土壤数据,构建了适合樟子松生长的环境因子数据库,并应用随机森林模型进行数据分析和建模,预测出樟子松在“三北”地区的潜在分布范围。研究结果表明:(1)影响樟子松分布的重要因子为气象因子,其中尤以温度影响最为重要;(2)樟子松主要分布区域是东北三省、华北地区大部、西北地区东部等,在西北其他地区也有零星分布。为该地区“三北工程”营造林树种选择提供科学依据。
By collecting and integrating relevant geographical,climatic and soil data,this paper constructs a database of environmental factors suitable for the growth of Pinus sylvestris var.mongolica,and uses random forest model for data analysis and modeling to predict the potential distribution range of Pinus sylvestris var.mongolica in the“Three-North”region.The results showed that the important factors affecting the distribution of Pinus sylvestris var.mongolica were meteorological factors,especially temperature;The main distribution areas of Pinus sylvestris var.mongolica are the three provinces in Northeast China,most of North China and the eastern part of Northwest China,and there are also sporadic distribution in other parts of Northwest China.It provides a scientific basis for the selection of afforestation tree species for the“Three-North Project”in this area.
