摘　　要：用胞映射方法对两种流域富营养化污染非线性简化系统的演化过程和全局性态进行了数值仿真、分析和探讨,结果表明:胞映射方法在解决流域时空混沌问题时表现出良好的解析能力,可从复杂动力学系统中提取常规方法无法获取的混沌形态、演化模式、奇异吸引域和吸引子特征,有助于深层次上认识和揭示复杂水域富营养化污染体系的演变过程和产生混沌的原因,为三峡库区富营养化污染的趋势预报和调控机制的研究提供新思路和实现技术。Cell mapping method is used for numerical emulation computing and analyzing the revolution, mechanism and global behaviors of two simplified nonlinear emulation systems of eutrophication polluting evolution along valley. The results show that cell mapping method has good solving capability on solving the problems of spatiotemporal chaos so that it could obtain in detail the information about polluted valley chaos, evolution of process, characteristics of strange attractors and those of the domain of strange attractions which could not be obtained from most common methods, exhibits the evolution of process and the reasons for the emergence of chaos in the complex eutrophication polluted system, and supply a new method for predicting the trend of eutrophication pollution along Yangtze River valley and researching the mechanisms for adjusting and controlling pollution evolution.
