基于投影寻踪模型的水-能源-粮食-人口系统安全评价
Water-Energy-Food-Population System Security Evaluation Based on Projection Pursuit Model
摘要
Abstract
As an indispensable part of the Beijing-Tianjin-Hebei metropolitan circle,the security and stability of water resources,energy,food,population and other resources in Hebei Province are particularly important for the economic and social development of the whole re-gion.Therefore,in order to deeply understand the security situation among water,energy,food and population systems in Hebei Province,population factors were included in the water-energy-food system for analysis,and a security evaluation index system of water-energy-food-population system was built.The spatial-temporal evolution of water-energy-food-population system in Hebei Province during 2010-2019 was comprehensively evaluated by using the projection pursuit model improved by Sparrow algorithm.The results show that during the study peri-od,the security level of water-energy-food-population system in Hebei Province is gradually increased,and the security difference of water-energy-food-population system is decreased.The security level values of water-energy-food-population system in all cities of the province range from 1.32 to 3.95,indicating that the system has three levels of insecurity,sub-security and security.By analyzing the stability of water-ener-gy-grain-population system,it is found that Hebei Province should rationally allocate resources according to its own resources advantages to realize the coordinated development of water,energy,food and population.关键词
