Evaluation of Coordination of Water-People-Land-Industry-City System in Tai'an City Based on DPSIR-Symmetric Cross-entropy Method
To implement the"Basing Four Aspect on Water Resources"strategy,a water-human-land-industry-city system evaluation model based on the DPSIR-symmetric interaction entropy was constructed.Using Tai'an City in Shan-dong Province as an example,by constructing an evaluation index system,a comprehensive evaluation of coordinated de-velopment was carried out.And then a coupling coordination development model was established to evaluate the develop-ment coordination degree among various subsystems.The research showed that the comprehensive evaluation values of each subsystem showed a fluctuating upward trend.Among them,the state(S)and response(R)subsystems showed the most stable fluctuating upward trend,while the pressure(P)subsystem was the most unstable;According to the his-torical system coupling coordination,the development of the water-human-land-industry-city system in Tai'an City since 2006 was divided into the transitional stage(2006-2010),the coordinated development stage(2011-2019),and the high-quality development stage(after 2020);The coordination degree of Ningyang County and Dongping County still needs to be improved.In the future,emphasis should be placed on promoting the construction of Tai'an City's water network,opti-mizing the water supply and demand structure,and upgrading the industrial structure.The above study can provide sup-port for Tai'an City's land and space planning as well as high-quality development of water resources.
