中国蜘蛛抱蛋属植物分布及生境特点的研究

A study on the distribution and habitats of Chinese Aspidistra Ker Gawl.

从植物区系分布分析着手 ,重点阐述了国产蜘蛛抱蛋属植物所在各种植被类型及其生境特点。现知全世界该属植物约有 50种 ,中国产 4 7种 (占该属种数的 94 % ) ,其中特有种 4 5种 (占该属种数的 90 % )。主要分布于中国长江以南尤其广西的 5个天然植被型 8个植被亚型中 ,特别在季雨林和常绿阔叶林中的种类最为丰富 (约 2 3种 )。它们是群落组成中一个不固定的成员 ,对环境中的荫闭度、湿度和土壤条件有着严格的要求。天然林的变化直接影响到它们的生存和发展。因此 ,要保护好该属植物并使其发展 。

WT5”BZ] This article desls with the distributions and habitats of Aspidistra Ker Gawl. in China.The genus that we know includes 50 species, among which 47 species grow in China ( about 94% of species to World ) and 45 species of endemic to China (about 90% of species to World ).They mainly distribute in 5 vegetation types and 8 vegetation subtypes of south of the Yangzi River especialy Guangxi. The species, which they are growing in seasonal rain forest and green broad leaf forst, are especially rich. They are changedable members in population ecology and need good conditions for shaded, humidity and soil. Their exist and developing are determined by variation of natural forest. So in order to protect the genus,We must protect the natural forest on which they depend. [WT5”HZ]
