摘要:

以贵阳市10种典型城市森林群落为研究对象,在野外抽样调查和实验室检测的基础上,采用单因素方差分析,分析了贵阳市不同城市森林群落植物多样性和土壤理化性质的差异,运用冗余分析和典范对应分析,探讨了贵阳市不同城市森林群落土壤理化性质对植物多样性及物种分布的影响,旨在为贵阳市乃至中国西南喀斯特城市森林生态保护、城市森林植物多样性维护提供重要科学依据和理论支撑。结果表明,(1)研究区有维管植物61科、107属、124种,不同类型城市森林群落不同层间重要值最高的物种不同,女贞桦木混交林物种组成丰富,马尾松林物种组成最贫乏。(2)各种城市森林群落物种Shannon-Wiener指数、丰富度指数和Pielou均匀度指数均以女贞桦木混交林最大,马尾松林最小,且二者相应的多样性指数间差异显著;灌木层与群落多样性指数变化相似,草本层Shannon-Wiener指数和丰富度指数以马尾松华山松混交林最大,Pielou均匀度指数以香樟林最大,且3个指数均以马尾松林最小,而Simpson优势度指数变化与其他3个指数变化相反。(3)不同城市森林群落的土壤pH、全磷、全钾、速效钾、速效磷、容重具有显著差异,而全氮、速效氮、有机质差异不显著,其中,土壤pH对物种分布及灌木层物种多样性有显著影响、土壤容重对物种分布及草本物种多样性有显著影响,土壤速效钾对物种分布影响不显著,但对群落物种多样性有显著影响,而土壤有机质、全磷则与之相反。

Abstract:

Taking ten typical urban forest communities in Guiyang as research objects, based on field sampling survey and laboratory test, the differences of plant diversity and soil physicochemical properties in different urban forest communities in Guiyang were analyzed by one-way analysis of variance. The effects of soil physicochemical properties on plant diversity and species distribution in different urban forest communities in Guiyang city were studied by using redundancy analysis and canonical correspondence analysis, aiming to provide important scientific basis and theoretical support for ecological protection and maintenance of urban forest plant diversity in Guiyang city and even Karst urban forest in southwest China. The results showed that: (1) There are 61 families, 107 genera, and 124 species of vascular plants totally. The plant species with the highest important values were different at different layers in different types of urban forests. The composition of the Mixed Plantation of Ligustrum lucidum and Betula alnoides mixed forest the most abundant, and the Pinus massoniana forest is the lowest. (2) The Shannon-Wiener index, richness index, and Pielou evenness index of various urban forest communities are the highest in Ligustrum lucidum mixed forest, and the diversity indexes of the Pinus massoniana forest is the lowest. There is a significant difference between the diversity indexes of the Pinus massoniana forest and the diversity indexes of Ligustrum lucidum mixed forest. The diversity index changes of shrub layer and community were similar, the Shannon-Wiener index and richness index of herb layer were the highest in Pinus massoniana and Pinus armandii mixed forest while the Pielou evenness index was the highest in Cinnamomum camphorum forest, and the three indexes were the lowest in Pinus massoniana forest, while the change of Simpson dominance index was opposite to the other three indexes. (3) Different urban forest communities of soil pH, total phosphorus, total potassium, available potassium, available phosphorus, bulk density has significant difference, but no significant difference of total nitrogen, available nitrogen, organic matter, among them, the soil pH on species distribution and the shrub layer has a significant influence species diversity, soil bulk density has significant effect on species distribution and herbaceous species diversity, Soil available potassium had no significant effect on species distribution, but had significant effect on community species diversity, while soil organic matter and total phosphorus, were opposite.

Key words: urban forest communities, plant diversity, species distribution, soil physicochemical properties, redundancy analysis, canonical correspondence analysis
