摘要：物种多样性和功能多样性广泛应用于生态学和保护生物等领域的研究,理清物种多样性和功能多样性之间的关系,对于深入理解生物多样性组分间的关系及生物多样性的保护意义重大。以香溪河流域为例,就水生昆虫物种多样性、功能多样性时空动态进行了分析,并就生物多样性指数间的关系进行了探讨。主要结果如下:物种丰富度介于2-44之间,冬季最大,春、秋季次之,夏季最小;香浓指数介于0.38-3.03之间,均值在冬季最大,春季次之,夏、秋季最小;均匀度指数介于0.89-1之间,表现为春、夏季大于秋、冬季。物种丰富度和香浓指数在4条河流间均表现为九冲河最大,香溪河次之,高岚河和古夫河最小;均匀度指数在4条河流间差异不显著。功能多样性方面,除功能丰富度指数表现为冬季最大,夏季最小外,其它指数在时空序列上均无显著差异。Pearson相关分析表明,功能丰富度、功能均匀度、功能离散度指数间相关均不显著;功能丰富度指数同物种丰富度和Shannon指数相关极显著;功能均匀度指数同物种丰度和Shannon指数相关显著;功能离散度指数同物种丰度和Shannon指数相关显著,同均匀度指数相关极显著。运用回归分析研究物种多样性对功能多样性的影响,结果表明,物种丰富度、Shannon指数对功能丰富度影响极显著,物种丰富度对功能均匀度影响显著,均匀度指数对功能离散度影响显著;物种多样性同功能多样性指数间拟合度整体不高。
Functional and species diversity are quantified in various fields of ecology and conservation biology. Disentangling the relationships between species and functional components of diversity should increase knowledge of biodiversity patterns and improve conservation strategies of biodiversity. This study uses a year’s monthly survey date of aquatic insects in the Xiangxi River system to do research on the spatio-temporal dynamics of species and functional diversity;and the relationship between species and functional indices were discussed. The main results as follows: among the seasons, the average of species richness, Shannon index, evenness index were 2-44, 0.38-3.03, 0.89-1.0 respectively;by one-way ANOVA analysis we found that species richness and shannon index were all highest in winter, and lowest in summer;while evenness index showed higher in summer and spring than autumn and winter. In spatial pattern, the species richness and Shannon index were all highest in the Jiuchong river, followed by the Xiangxi river, and lowest in the Gaolan and Gufu river;while, the evenness index had no significant difference among the 4 river. Spatio-temporal dynamics of functional diversity indices were also analysed, and the results showed that only the functional richness had significant difference among seasons, other indices had no significant difference among the spatio-temporal patterns. Pearson correlation analysis was used to study the relationship among the diversity indices, and the results showed that there were no significant correlation among the 3 functional diversity indices(functional richness, functional evenness, functional divergence). The correlation of functional richness with species richness and Shannon index were extremely significant;the correlation of functional evenness with species richness and Shannon index were significant;while, the functional divergence not only significantly correlate with species richness and Shannon index, but also have extremely significant correlation with species evenness. Regression analysis was used to study the effect of species diversiy indices on functional diversity indices, and the results showed that functional richness was seriously influenced by species richness and Shannon index;functional evenness was significantly impacted by species richness;and functional divergence was significantly impacted by Shannon index and species evenness.
