- Abstract
After building the entropy indexes system of the watershed hydropower exploration and environment system, by using Shannon information entropy theory, the “pressure-type positive entropy” and “support-type negative entropy” were calculated. By defining system total entropy flow and disturbance coefficient, stability of the system and disturbance ability of hydropower exploration activity was analyzed. Finally the case study of Zishui River basin was made to verify this model. The conclusions show that first, the value of total entropy flow was positive in 2006 and the watershed environment system was developing into disordered state and was unsteady. From 2007 to 2016, the value of total entropy flow was negative. The order degree was strengthened and the system was in virtuous cycle state. Second, during the study period, the disturbance coefficient was in oscillation development. Except 2011 and 2014, in most of time, disturbance coefficient was negative and the negative entropy increased quickly which represented that Zishui River basin was vigorous.
