Research On Co-evolution Of Human-Water System In Huangshui River Basin

In recent years,the social economy has continued to develop,but it has caused waste and pollution of water resources.The relationship between people and water has encountered unprecedented challenges and tests.Humans need to strengthen their comprehensive understanding of water and re-measure the relationship between people and water.Relationship.Social hydrology regards the human social system and the hydrological system as a unified whole,that is,the human-water system.The two influence each other and undergo coordinated evolution.The coordinated evolution of the human-water system is a complex geographical process and has become the core of social hydrological research.Based on this article,through the human-water system coevolution model,it reveals the feedback mechanism and co-evolution effect between human society and hydrological systems,simulates the dynamic mechanism of humanwater system evolution,and observes and understands the direction of human-water system co-evolution,with a view to Provide guidance for sustainable regulation of river basin human-water relations.This paper takes the Huangshui River Basin as the research object and builds an evaluation index system for the co-evolution of the human-water system in the Huangshui River Basin.Based on the relevant statistical data of the administrative counties and districts of the Huangshui River Basin from 2005 to 2017,the two subsystems of the human society and the hydrological system of the Huangshui River Basin The comprehensive development level of the system is evaluated,and the information entropy model and the co-evolution dynamic model of the human-water system are established.The direction and state of the co-evolution of the human-water system in the Huangshui River Basin are discussed.The co-evolution process of the human-water system in the Huangshui River Basin is analyzed and proposed.The countermeasures for the coordinated development of the human-water system in the watershed are as follows:(1)The development level of human society and hydrological subsystems of the human water system in Huangshui River Basin from 2005 to 2017 showed a gradual upward trend in the course of time,and the development level of the development of human social subsystems was faster than that of hydrological subsystems This indicates that the development level of water resources and environment in Huangshui River Basin is relatively slow in the process of continuous development.(2)The information entropy value of the human-water system in the Huangshui River Basin generally decreases year by year.Specifically,the system entropy values of Chengzhong District,Chengdong District,Chengxi District,Chengbei District and Huangzhong District showed a rapid downward trend;Huzhu County,Honggu District,Datong County,Ledu District,Minhe County and Ping An The system information entropy value of the district decreased slowly from 2005 to 2009,and the system information entropy value began to show a downward trend from 2010 to 2017.Tianzhu County,Huangyuan County,and Menyuan County all had system information entropy values during the study period.The trend is declining and relatively flat;Gangcha County,Qilian County,Tianjun County and Haiyan County have a slow increase in the system information entropy value from 2005 to 2009,and a slow decline in the information entropy value from 2010 to 2017.(3)The degree of systematic order of the human-water system in the counties and districts of the Huangshui River Basin is increasing year by year,and the system is developing to an orderly and stable state,and the differences between regions are more obvious.Among them,Chengzhong District,Chengdong District,Chengxi District,Chengbei District and Huangzhong District have the fastest growth in orderliness;Huzhu County,Honggu District,Datong County,Ledu District,Minhe County and Ping'an District during 2005-2009 The degree of order increases slowly,and the degree of order increases between 2010 and 2017 and the range is large;the order degree of the three counties in Tianzhu County,Huangyuan County and Menyuan County continues to increase;Gangcha County,Qilian County,The order degree of the system in Tianjun County and Haiyan County was a negative value from 2005 to 2009.From 2010 to 2017,the degree of order began to increase slowly and positively.(4)A comprehensive analysis of the co-evolution status of the human-water system in the Huangshui River Basin shows that the orderly development level of Chengzhong District,Chengbei District,Chengxi District,Chengdong District,Huangzhong District,Huzhu County and Honggu District is relatively high,and coordination The type of evolution is synergistic;the orderly development level of Ping'an District,Ledu District,Minhe County,Datong County,Tianzhu County,Huangyuan County and Menyuan County is in a middle position,and the type of co-evolution is conflict type;Gangcha County,Qilian County,Tianjun County and Haiyan County have a low level of orderly development,and the type of co-evolution is development.
