喀斯特区小生境特征现状分析:以茂兰自然保护区为例

Analysis on Microhabitat Characteristic in Karst Region——Taking Maolan nature reserve as an example

根据茂兰喀斯特区发育的复杂多样的生境现状,划分了石面、石沟、石缝、石洞、石台、石槽和土面7种小生境类型,并解释了不同小生境的特征。根据生境所占面积结合相似性系数划分了4种生境组合类型,即土面—石面—石台型,石面—石沟—石台型,石面型和石面—石台型。

Seven microhabitats of stony surface, stony gully, stony crevice, stony cave, stony dais, stony pit and soil surface were divided according to the development current situation of complex and diverse habitats in Maolan Karst region. The paper describes the characteristic of different microhabitats and introduces 4 combination habitat types of soil surface to stony surface to stony dais, stony surface to stony gully to stony dais, stony surface, and stony surface to stony dais in the light of the area of every microhabitat and analogical coefficient.
