非线性理论在水文学中的应用研究及展望

Application research of non-linear theory in hydrology and its prospect

针对水文系统中存在的非线性现象与水文尺度问题,基于目前研究成果重点分析了混沌、分形和小波分析理论在水文系统中的应用研究现状和存在的主要问题,探讨了未来的研究方向和发展趋势。上述非线性理论的引入,不但为水文水资源的研究提供了新的思路,加深了对水文运动规律的认识,而且拓宽了水文学的研究范畴,同时也推动了非线性理论本身的发展。

In view of on the non-linear phenomena and scaling problem in hydrology and on the basis of current study results, this paper analyzes with the emphasis on the application and main existing problems of chaos, fractal and wavelet analysis theory to the hydrologic system, and discusses its future study direction and development trend. The introduction of above-mentioned non-linear theories not only points out new thinking concept and deepens the understanding of hydrologic movement laws, but also widens the study scope of hydrology and promotes the development of non-linear theory itself.
