黄河河口湿地植被分布及其与环境因子关系
The Distribution of Vegetation and Its Relationship with Environmental Factors in the Yellow River Estuarine Wetland
摘要
Abstract
[Objective] The aim was to study the distribution of vegetation and its relationship with environmental factors in Yellow River estuarine wetland. [Method] According to the data of the plant sample investigation and the related environmental factors in Yellow River Delta National Nature Reserve in 2009 -2010, the plant community changes and its relationship with environmental factors in temperate estuary wetland were analyzed. [ Result] There are few vegetation in the Yellow River delta and the distribution of plants are influenced by environment. Judging from the vegetation structure, the vertical structure of vegetation in the pratidal zone vegetation cover included arbor layer, shrub layer and grass layer. The importance of grass was larger than shrub and arbor. In the intertidal zone, the vertical structure of plants was divided into shrub and herb layers. Judging from the variety, the species in the pratidal was higher than that in the intertidal. The first principal component elected by Principal Component Analysis better reflects the salt of the study area, and the second principal component better reflects nutrient information. Regression analysis showed a positive correlation between importance value and the total salt content and electrical conductivity. In other words, if the total salt content and electrical conductivity increases, the importance value rose. However, the diversity index decreased as the total salt content and electrical conductivity increased. [ Conclusion] The study provided theoretical basis for the ecological protection of vegetations and formulation of regional policies.关键词
