摘　　要：本文从理论上对动态系统脉冲响应函数与水文状态预报方程进行了推导与计算、对系统特征进行了分析．然后，以湖南省炎陵县河漠水流域为研究对象，对流域系统不同年份的系统脉冲响应函数进行了辨识，比较了不同年份的脉冲响应函数曲线，评价与分析了森林状态的变化对水文状况的影响．根据系统脉冲响应函数，可对流域系统的水文状况进行预报．The dynamic system pulse response function (SPRF) and the hydrologic state forecast equations have been deduced out theoretically and the characteristics of the system have also been analysed. Taking the Hemoshui River Basin in Yanling County of Hunan Province as the studying object,this article has identified and simulated its SPRF in different years, and compared the curves of SPRF in different years. The effect of the change of forest state on the hydrologic state of the River Basin has also been analysed and evaluated. Based on this SPRF,the hydrologic state process of the River Basin can be forecasted.
