摘要
白皮松(PinusbungeanaZuc.exEndl.)分布在29°55′~38°25′N和103°36′~115°17′E的范围内,在我国山西、陕西、甘肃、河南、四川、湖北及湖南北部7个省区均有分布,分布区横跨暖温带、北亚热带及中亚热带3个气候带...
Based on the climatic data of 40 representative plots in the distribution area of Pinus bungeana Zucc., the distribution area can be divided into 6 climatic regions: the North, the West, the middle, the southmiddle, the southwest and the South respectively by the method of PCA(principle components analysis) and ISODATA cluster analysis. The results show that in the distribution area of P. bungeana Zucc., the geographical locations of different climatic regions are discontinuous and the differences of climatic condition among the regions are very significant. The growth pattern of trees and distribution trends is related to climatic condition closely. Furthermore, the typical picking sites for provenance test are selected.
