摘要
介绍了分形理论中盒维数的定义及其理论求解方法,给出了流量过程线的分维估算方法;运用此理论研究了雅砻江锦屏二级电站猫猫滩闸址处典型年天然月平均流量和人工调节下泄的月平均流量过程线的形态特征。运用分形理论中分维数D描述流量过程线形态特征,分析了不同典型年天然和人工调节二者流量过程的特征差异,对工程建设水文情势影响评价和"生态调度"提供了有益的参考和借鉴。
This paper introduces the definition of box-counting dimension and its theoretical solution algorithm in fractal theory and gives the computation method of fractional dimension in discharge hydrograph. The fractal theory is applied to study the natural and regulative monthly mean discharge process shape characteristics of Maomao Gate Dam in Yalong River. The feature differences between the yearly typical natural discharge and regulative discharge process are analyged by using the fractional dimension to describe the discharge hydrograph shape characteristics. It provides the reference for the impact assessment of hydrologic regime and “ecological dispatch” in engineering construction.
