摘要

摘要: 为探明我国湖泊营养物浓度及富营养化状态的空间分布特征，利用相关性分析和曲线拟合方法分析了我国湖泊的TN浓度和TP浓度，浮游植物生物量（Chl-a浓度）以及湖泊营养状态指数（TLI）与湖泊所处地理位置指标经度、纬度和海拔的关系（文中数据未含港澳台）。结果发现，我国湖泊TN浓度和TP浓度与经度和纬度显著正相关，与海拔显著负相关；但纬度对TN浓度和TP浓度变化的解释度仅为3.0%和3.7%，小于经度和海拔对TN浓度和TP浓度变化的解释度。Chl-a浓度和TLI随经度的升高而升高，随海拔的升高而降低，与纬度的相关性较弱。

Abstract: In order to understand the spatial distribution characteristics of lake nutrient concentrations and eutrophication states in China, correlation analysis and curve fitting were used to illustrate the relationships between eutrophication-related parameters, such as total nitrogen (TN), total phosphorus (TP), phytoplankton biomass (Chl-a) and trophic level index (TLI), and geographical location parameters, such as longitude, altitude and elevation. The results showed that the concentrations of TN and TP were strongly positively correlated with the longitude and altitude, and negatively correlated with the elevation. However, the variations of TN and TP explained by altitude were only 3.0% and 3.7%, being lower than that explained by longitude and elevation. The concentrations of Chl-a and TLI increased with the longitude and decreased with the elevation, and weakly correlated with the altitude.
