摘要
选取云南石林不同石漠化发展状况的密枝林、白龙潭村、芝云洞、白龙潭天窗4个样地,对其进行植被群落调查分析.结果显示,以轻度石漠化为代表的密枝林原生性植被群落结构复杂,抗旱能力强;而重度石漠化地点的白龙潭天窗植被结构单一,退化严重.从样地的调查情况分析,在选择区域植被恢复时,主要应遵循原生性、乡土植被,乔灌木多样性结合的原则.
Four sample areas are selected for investigation of vegetation types in Shilin Geological Parks:Mizhi forest, Bailongtan village,Zhiyun hole,and Bailongtan skylight.The result shows that Mizhi forest,representative of mild rocky desertification, has complicated primordial vegetation which is highly resistant to drought;and Bailongtan skylight,a severe rocky desertification land,has simple vegetation structure and its vegetation is heavily degraded.According to the investigation, protophyte,local vegetation and various trees and shrubs should be chosen for restoration.
