Abstract:
Forest germplasm resources are the basis of forestry construction and development, and they had very important relationships with the beautiful needs of human life, ecological security and ecological civilization construction. The wild tree germplasm resources in Jian’ge County of Sichuan Province were carried out in the field and analyzed by means of general survey, key investigation, interview and data collection. The results showed that: (1) there are 47 species(66 copies) of wild forest germplasm resources, belonging to 28 families and 36 genera. 36 species of trees, accounting for 76.60%; There are 9 kinds of shrubs, accounting for 19.15%; There are 2 species of woody vines, accounting for 4.25%. (2) In terms of vertical distribution, wild forest germplasm resources in Jian’ge county were mainly distributed in low mountains to middle and low mountains between 800 and 1600m, accounting for 62.12% of all species. Among them, 23 kinds of wild forest germplasm distributed in the low and medium mountainous areas with an altitude of 1000 ~ 1500m, which was the largest distribution area of wild forest germplasm resources. (3) In terms of horizontal distribution, wild forest germplasm resources were mainly distributed from the east to the north, accounting for 69.70% of all wild forest germplasm. There was almost no wild forest germplasm distribution in some villages and towns in the southwest China. Moreover, some suggestions were put forward for the protection and utilization of wild forest germplasm resources in Jian’ge county.
