摘要
中国南方丹霞地貌丰富的地形地貌为群落和生态系统多样性创造了的条件,而生态系统多样性又是群落多样性的基础。文章针对中国南方主要丹霞地貌区的群落和生态系统,进行了初步的数据统计与实地调查,结果表明:丹霞地貌区域内植物群落和生态系统类型十分丰富,有17个植被型,185个群系;生态系统类型有47类,自然生态系统14类,人工生态系统15类,复合生态系统18类。其中包含有3种丹霞地貌特有群落和2种特殊生态系统。另外,丹霞地貌区小尺度范围内高度多样化的生态系统在整个地貌区普遍存在,这也是南方丹霞地貌区生态系统复杂化和高度复合化一种体现。
Danxia landform has abundant terrain and geology, which formed various biological diversity and various ecosysteins. Multiple and complex environments are premise of forming various vegetation community and ecosystem. The results showed that there are 17 vegetation types and 185 vegetation formations, and 47 types of ecosystems (14 natural ecosystems, 15 artificial ecosystems and 18 compound ecosystems) in Danxia landform, including 3 unique plant communities and 2 special ecosystems form in part due to the unique environmental condition in Danxia landform. In addition, it is common that various ecosystems exist within a small scope in Danxia, which reflects the complexity and integrality of ecosystems in a small scope in Danxia landform.
