【摘要】 山西省位于黄河中游，黄土高原东部，生态区位十分重要。山西省湿地植物对湿地生境的变化敏感，但对湿地植物功能性状综合性，对其生态策略、空间分布格局及与气候变化的耦合研究尚不充分。本研究运用植物的竞争-耐胁迫-自由(CSR)策略，从湿地植物功能性状出发，采用PCA分析和Pearson相关分析，确定山西省湿地植物的主要CSR策略类型，研究湿地不同对策类型的空间分布格局和其与气候因子的关系，探究物种丰富度与植物CSR策略的关系。结果表明：(1)山西省湿地植物的CSR策略主要为C策略植物、CS策略植物和SR策略植物。(2)C策略植物与海拔极显著非线性相关(P<0.001),与经度极显著负相关(P<0.001),与纬度极显著非线性相关(P<0.001);CS策略植物与纬度负相关(P<0.05);SR策略植物与海拔(P<0.01)和纬度(P<0.05)正相关。(3)C策略植物与年均温(P<0.001)和降水季节变异(P<0.001)之间存在极显著非线性相关关系；CS策略植物与年降水量正相关(P<0.01),与气温季节变异负相关(P<0.01);SR策略植物与年均温负相关(P<0.01),与降水季节变异之间存在非线性相关关系(P<0.01)。(4)SR策略植物与丰富度正相关(P<0.01)。综上，海拔和纬度作为间接因子影响着湿地植物CSR策略，年均温和降水季节变异则是影响植物CSR策略的直接因子，两者对植物对策类型的共同作用导致现有山西省湿地群落的物种共存机制的形成。本研究可为山西省湿地的保护和修复提供理论基础。更多还原

【Abstract】 Shanxi province is in the middle reaches of the Yellow River, the eastern part of the Loess Plateau of China. It holds a crucial ecological niche. Wetland plants in Shanxi province are sensitive to the changes in wetland habitats, but there was less knowledge of their comprehensive functional traits, ecological strategies, spatial distribution and coupling with climate change.In this study, CSR strategies(Competitive-Stress tolerant-Ruderal) theory were applied to identify the main CSR strategy types of wetland plants in Shanxi province from the functional traits of wetland plants; it used PCA analysis and Pearson correlation analysis to study spatial layouts of wetlands with different CSR strategies and their relationship with climate factors, and explored the relationship between species abundance and plant CSR strategies.It found(1) wetland plants in Shanxi province were mainly C-strategy plants, CS-strategy plants and SR-strategy plants.(2) There were highly significant non-linear correlations between C-strategy plants and elevation(P<0.001), highly significant negative correlations with longitude(P<0.001), and highly significant non-linear correlations with latitude(P<0.001); CS-strategy plants were negatively correlated with latitude(P<0.05); and SR-strategy plants were positively correlated with elevation(P<0.01) and latitude(P<0.05).(3) There were highly significant non-linear correlations between C-strategy plants and mean annual temperature(P<0.001) and seasonal variability of precipitation(P<0.001); CS-strategy plants were positively correlated with annual precipitation(P<0.01) and negatively correlated with seasonal variability of temperature(P<0.01); SR strategy plants were negatively correlated with mean annual temperature(P<0.01), and there was a nonlinear correlation between them and seasonal variability in precipitation(P<0.01).(4) SR strategy plants were positively correlated with abundance(P<0.01).In summary, elevation and latitude as indirect factors influenced wetland plant CSR strategies, while seasonal variability in mean annual temperature and precipitation was a direct factor influenced plant CSR strategies. The combined effect of the two on the types of plant contingencies leads to the formation of the existing species coexistence mechanism of wetland communities in Shanxi province.This study can provide a theoretical basis for the conservation and restoration of wetlands in Shanxi province.更多还原
