| 摘 要： | 对南水北调中线工程河南受水区水资源系统动力学特征进行了分析研究,给出了各子系统动力学特征指标和水循环之间的定性关系,揭示了各子系统的分形特征、复杂程度和演化规律.结果表明,该水资源系统具有明显的分形结构和混沌特征,为一个非线性系统,且系统演化存在一个奇异吸引子;从大气降水-地表水-浅层地下水-深层地下水水循环角度看,该系统的开放程度和受外界干扰的程度逐渐减小;从大气降水-地表水-浅层地下水的水循环角度看,该系统的复杂程度符合水资源系统的一般情况.分析成果对该区寻求改善水资源系统行为的机会和途径具有重要参考价值.

| Abstract: | The dynamic characteristics for water resources system of water receiving district in Henan province of the middle route project of south-to-north water transfer is analyzed in this article,the qualitative relationship between the dynamic characteristic indexes and water cycle in each subsystem is given,and the fractal characteristic,complex extent and evolution rules are revealed.The results show that there are obvious fractal structure and chaotic characters in the system,which is the non-liner and there is a strange attractor during evolution,and its opening extent and resistance capacity reduce gradually from the water cycle system of precipitation-surface water-groundwater-deep underground water,and it mees the normal rules of water resources system from the cycle of precipitation.surface water-groundwater.The results provide an important reference for finding chances and means to improve the behavior of the water resources system. |
