摘  要:
采用时空替代法,运用3S技术,结合植物群落实地调查,研究了云南西北高原典型退化湿地纳帕海的植物群落景观多样性格局。结果表明:人为干扰加速了纳帕海原生沼泽、沼泽化草甸植物群落景观向草甸、垦后湿地植物群落景观演替,湿地环境不断丧失,湿地功能逐渐退化;不同演替阶段沼泽植物群落景观多样性在空间上呈现出不同的格局是对湿地环境变化的响应,体现了湿地环境变化与功能现状,并在一定程度上反映了人为干扰的类型与强度。

摘  要:
The Napahai wetland in Northwest Yunnan is a typical degraded plateau wetland. By the temporal-spatial substitution method and 3S technology, and combining with filed survey, the landscape diversity of the plant community in Napahai wetland was studied, with the driving forces investigated. The results showed that under human disturbance, the succession from primary swamp and swampy meadow to meadow and reclaimed wetland plant community accelerated, wetland environment kept losing, and its function declined gradually. The spatial variation pattern of the landscape diversity of plant community at different succession stage was the response to the change of wetland environment, which reflected the current status of the aquatic environment and function of the wetland, as well as the type and intensity of human disturbance.
