Investigation of Population Status of Abies ziyuanensis in Ecological Area of Nanshan National Park in Hunan Province
The status of the wild population growth of Abies ziyuanensis is crucial for formulating population conserva-tion measures and biodiversity protection.In this study,we conducted field surveys on A.ziyuanensis populations in Nans-han National Park in Hunan,using plot and quadrat sampling methods.We analyzed the quantity distribution,habitat char-acteristics,population composition,age structure,and height-diameter tree structure of the current populations.The results showed that the number of wild plants of A.ziyuanensis in Hunan Nanshan National Park was 106(excluding seedlings).The altitude of its distribution area ranged from 1 450-1 900 m,the soil was montane yellow-brown soil,the average an-nual temperature was 9.5-14.5 ℃,the average annual rainfall was 1 218-2 018 mm,and the average annual relative hu-midity was 79.2％-85.6％.The existing community structure was intact and shows clear tree,shrub and herb layers.The age structure showed some anomalies,and the height-diameter tree differences among different populations were signifi-cant(P＜0.05).Considering the issues of regeneration and breeding in the existing population,we propose conservation strategies for A.ziyuanensis from three aspects:increasing the population size,improving the community structure and age structure.The findings and conservation strategies for A.ziyuanensis can provide references for the protection of popula-tions in southern China.
