摘要
本文利用灰色系统理论中的灰关联空间分析研究了玄武湖各水质指标间的关联程度。借助于GM(1,N)群模型,建立了玄武湖灰色动态模型并对水质因子作了趋势预测。该项研究对湖泊生态系统的水质建模有一定的参考意义。
By the theory of relational space of grey system, the author of this paper discusses the uncertainty relation among the water quality idexes of Xuanwu lake in Nanjing. Based on the GM (1, N ) group models, a dynamic system model is established and the factors of water quality of the system are predicted. The process of modelling has a certain reference significance for other lakes.
