摘　　要：如何实现人口、经济、社会、资源、环境系统的协调及可持续发展,是全人类共同面临的难题。以甘肃全省及其各市州为研究对象,基于GIS技术和各种数学分析方法,开展人口-经济-社会-资源-环境系统协调及可持续发展时空综合测度研究。结果表明:甘肃省及各市州的可持续发展综合水平总体上均呈现逐步上升趋势。甘肃省及各市州5大系统的耦合协调发展水平均保持稳步上升的良好趋势。可持续发展综合水平重心总体上在向东南方向移动,各子系统可持续发展水平重心,大致沿西北—东南方向分布。5大系统耦合协调度重心大致向东偏移,但偏移幅度不大,其演变相对比较平稳。How to achieve the coordination and sustainable development of population,economy,society,resource,and environment system is a common problem facing all mankind.This research uses various mathematical analysis methods and GIS technology on the Gansu Province,China and its sub-regions to conduct the spatial-temporal comprehensive measurement of coordination and sustainable development of population-economy-society-resourceenvironment system.It makes up for the lack of the research of sustainable development form single angle,and it provides theoretical support and decision-making basis to realize a strategy for the sustainable development of Gansu Province.The results are as follows.Overall,the comprehensive level of sustainable development in Gansu Province shows gradual upwards.Among them,the level of sustainable development of economic and social subsystems is growing faster.The sustainable development level of population and environment subsystems is growing steadily,and the sustainable development level of resource subsystem fluctuates greatly.The comprehensive level of sustainable development in each city and state shows a gradual upward trend.However,the increase is limited and volatile in some areas.Among them,the development trend of sustainable development level of each subsystem is different with obvious spatial differences.The coordination development level of the five systems in Gansu Province keeps a good steady rising trend.The evolution of the coordination development level of the five systems in each city and state is basically in line with the steady growth trend.The evolution trend is basically consistent with that of the whole Gansu province.Among them,the number of regions in the state of maladjusted recession and on the verge of maladjusted recession is gradually decreasing,while the number of regions in the state of coordination development and reluctant coordination development is gradually increasing.On the whole,the gravity center of the comprehensive level of sustainable development is m
