| 中文摘要: |
| 以2009年4月太湖生态学实验数据为基础,研究了15、20、25、30m格网分辨率下NPZD生态动力学模型模拟结果的差异性。结果表明,格网分辨率和平均浓度及浓度均方根之间存在较复杂的关系,难以用统计方法加以描述。总体而言,格网分辨率的不同,生态动力学模型计算得到的磷浓度、悬浮泥沙浓度和叶绿素a浓度的平均值、均方根和空间布局也将不同。在实际应用中,应该选择适宜的格网分辨率进行生态学参数模拟,进而实现对太湖水体状况的正确模拟与预测。 |
| 英文摘要: |
| The otherness of simulation results of NPZD ecological dynamics model was researched and analyzed under grid resolution，respectively 15 m，20 m，25 m，and 30 m on the experimental data surveyed in April，2009，in Taihu Lake. The research indicated that relationships between grid resolution and average concentration，andrelationships between grid resolution and root mean square concentration were complicated to describe in statistic methods. With grid resolution varying，the mean value，root-mean-square and spatial distribution of the density of phosphorus，chlorophyll-a，and suspended sediment computed with NPZD ecological dynamics model would be different A choice of suitable grid resolution should be made practically for ecological simulation of parameters to simulate and forecast the aquatic status in Taihu Lake.
