Relationships between Plant Community Characteristic and Soil Factors in Binhai New Area of Tianjin
Based on the investigation on plant community and soil factors of Binhai New Area using transects methods between July and September,2008,the relationships between plant community and soil factors in Binhai New Area were researched.Canonical Correspondence Analysis (CCA) was applied to analyzed the species-environment and samples-environment two-dimensional ordination diagrams.There were 46 families,135genera,232 species,61 salt-tolerant species.The wetland plants were divided into 4 subtypes:aquatic plants,humidogene plants,meso-xerophytism and xerophytism.Sorting among the 23 quadrates demonstrated that the position of different populations had related to the soil factors.Disparities between water content and salt content in the soil were the most important factors in the formation of vegetation pattern of Binhai New Area,available nitrogen content was the second important factor,while pH,orgnic matter content,available potassium content and nitrogen content were not related with the vegetation pattern.All these factors determined the population positions and characteristic.The sorting of dominant species had similar resuits with quadrates.
