摘要

摘要: 选择洪湖流域为研究区域，应用分布式流域模型SWAT，从长期演化的角度出发，对流域营养盐输移演化进行模拟。模拟的边界条件设置为自然农耕背景，探讨百年尺度洪湖流域营养盐输移演变规律。对TN、TP的模拟分汛期与非汛期两个时间段，分别进行200年的模拟运算。模拟结果显示模型可以很好的体现流域营养盐沉积输移演变的基本特征。TN、TP浓度变化有明显的季节特征，随时间变化特征与沉积记录相一致。模拟结果的时间序列分析，TN、TP显示出不同的变化趋势。流域模型为百年时间尺度上流域营养盐沉积输移演化的自然趋势研究，提供了很好评价依据。

Abstract: A catchment's nutrient model SWAT was used in this paper to examine changes in the nutrient sedimentation and transportation in a hundredyear time scale, and Hong Lake Basin, located in the middle reach of Changjiang River was chosen as the study area. Boundary condition in the simulations is prescribed in a preindustrial time mode in order to evaluate a naturalagricultural forced nutrient changes in the Hong Lake Basin one hundred years ago. Total nitrogen (TN) and total phosphorus (TP) in the main channel transported into the lake were simulated in two periods of flood season (summer) and nonflood season (spring, fall and winter) in running 200 model years respectively. Results show the modeling can catch basic features of the basin nutrient transportations and changes. The TN and TP concentrations show significant seasonal changes, and annul mean concentration can be compared well with nutrient concentrations transformed from sediment cores of Hong Lake that records were 137Csdated to ca 100 year ago. Time series in the 200yr simulation shows different trends in TN and TP concentration changes. There are obvious differences spatially in the input and output subbasins. The SWAT model has provided an effective tool to evaluate how nutrient production and changes in natural environmental system of the 200 years in the Hong Lake Basin.
