摘要:
均匀布点开展纳帕海湿地区植物群落调查，应用DCA排序分析植物群落演替特征及其主控因子，利用Shannon-Wiener等物种多样性指数分析群落演替过程中的物种多样性变化态势；利用多期Landsat TM/ETM+影像解译获取多年平均的湿地区淹水频率空间分异特征；均匀布点采集并测定分层土样重量含水率，生成植物调查同期湿地区分层土壤含水量空间分异特征；将样方DCA第一排序轴与样方物种多样性指数进行关联分析。结果表明：本次调查记录到湿地区植物物种130种，隶属36科88属；湿地区的湿-中生植物群落占绝大多数，中生群落和严重破坏地次生群落分布较广，典型水生植物群落分布生境狭窄，可分为水生植物群落、湿-中生植物群落、中生植物群落和严重破坏地植物群落4个演替阶段；水文情势分异及变化和强干扰是纳帕海湿地植被生态演替的主控因子；现状演替态势下，湿地区的湿-中生植物物种、与人为干扰或退化有关的伴生植物物种会趋向增加，湿地进一步退化；调控水文情势和减轻家畜翻拱的强干扰破坏是实现纳帕海湿地植被生态修复的重要途径。
Abstract:
Through dividing Napahai wetland of Yunnan,China into hundreds of equalsize grids, quadrat sampling was adopted to investigate herbaceous communities and species in each accessible grid. Detrended Correspondence Analysis (DCA) ordination was used to reveal the community succession phases and the major driving factor. Four species diversity indices were calculated for all community samples. Then we explored the impacts of the variation of the major driving factor indicated by DCA AX1 upon community species diversity. The study recorded 130 species, grouped into 88 genera and 36 families. Within the wetland, the mixed hygrophytemesophytes are the most widely distributed communities, then the mesophytes, the secondary communities on severely damaged habitats, and the hydrophytes, which are the four succession stages. DCA ordination showed the gradient variation of hydrological regime is the primary factor to determine the community succession stages of Napahai wetland; while, freerange pig directly caused the severe damage of wetland habitats and then the secondary community succession. Present hydrological regime of and freerange animal husbandry within the wetland will lead to the increase of hygrophyte and mesophyte scpecies, as well as some companion species related to disturbances, which indicates higher potential risk of community degradation. Regulating hydrological regime to increase flooding area and frequency, and adopting enclosure breeding to weak livestock (especially the pigs) disturbance are the basic measures to promote community restoration of Napahai wetland.
