摘要
河北省作为京津冀城市圈中不可或缺的一部分,其水、能源、粮食、人口等资源安全稳定对于整个区域经济和社会的发展尤为重要.为了深入了解河北省水-能源-粮食-人口系统的安全状况,将人口因素纳入水-能源-粮食系统进行分析,构建水-能源-粮食-人口系统的安全评价指标体系,运用基于麻雀算法改进的投影寻踪模型对河北省 2010-2019 年水-能源-粮食-人口系统安全进行时空演变综合评价.结果表明:在研究期,河北省水-能源-粮食-人口系统安全等级逐渐升高,各市的水-能源-粮食-人口系统安全差异性降低;河北省各市水-能源-粮食-人口系统安全等级值在 1.32～3.95 之间,说明该系统安全处于不安全、亚安全、安全 3 个等级.建议河北省根据自身资源优势,合理分配资源,实现水、能源、粮食和人口的协调发展.
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.
