摘要
采用GIS技术对河西走廊山地-绿洲、荒漠复合生态系统的景观多样性进行了研究。研究结果表明:绿洲景观生态系统和山地景观生态系统的最大景观多样性指数最大;绿洲景观生态系统的景观多样性指数最大,其次为山地景观生态系统,荒漠景观生态系统由4种景观组分组成,其最大景观多样性指数和景观多样性指数最小;均匀度最高的为绿洲景观生态系统,其次为山地景观生态系统,最低的为荒漠景观生态系统;三类景观生态系统的景观优势度都不高。
Landscape diversity of the MetaEcosystem Consisted of Mountain, Desert and Oasis in Hexi Corridor,Gansu,China are studied with GIS. The results showed that: oasis landscape ecosystem and mountain landscape ecosystem have the same maximum landscape diversity, because this two landscape ecosystems have the same number landscape elements; oasis landscape ecosystem has the biggest landscape diversity, desert landscape ecosystem has the smallest landscape diversity and maximum landscape diversity; landscape superiority of 3 landscape systems is not notable high.
