株洲市城郊植物多样性调查研究

Investigation and research on natural botanical diversity in Zhuzhou suburban

植物多样性是生物多样性的重要层面,园林绿化是人工群落组成部分。保护生物多样性,模拟地带性人工植被,才能实现园林绿化低成本、高效益、高生产力、高生物量的总体目标。因此,对城郊天然林调查有其必要性。调查结果表明:株洲城郊有种子植物约500种(不含栽培植物),隶属73科,187属,其中木本植物193种,草本植物300余种。过渡特征明显,特有成分丰富,观赏植物资源众多,外来种是株洲城郊生物多样性重要成分。其结果为人工模拟天然植被与保护生物多样性提供科学依据。

Botanical diversity is an important branch of biodiversity. Gardens virescence is one part of artificial community. Protecting biodiversity and imitating zone artificial vegetation are to realize general objective of gardens virescenee with low cost, high efficiency, high productivity and high bio-quantity. So it is necessary to investigate natural forest in suburbs. The results of investigation showes that there are about 500 plants species（excluding cultivating plants） which contain 193 woody plants and more than 300 herb belong to 73 families and 187 genera in Zhuzhou suburbs. Besides obvious intermediate features, affluent special compositions, multitudinous ornamental plants and foreign plants are great ingredients of biodiversity. The results can offer scientific basis for artificial imitated natural vegetation and protecting biodiversity.
