摘　　要：科学认知人类活动与地域系统的互动关系是实现人地关系协调发展的重要依据。该研究构建了人地关系协调发展压力-状态-响应(Press-State-Response,PSR)评价理论体系,并利用2002、2007、2012和2017年中国省域截面相关数据,分析了中国人地关系协调发展时空演化特征及其空间分异影响因素。结果表明:1)2002-2017年中国人地关系协调发展等级总体处于中度协调至良好协调之间,较为稳定。而协调度值则表现为"V"型特征,2002-2007年协调度值由0.648降低到0.494,2012年回升到0.639,2017年进一步提升到0.705。15年间中国人地关系经历了"先趋紧-后缓解"的发展过程。2)从空间上看,15年来中国人地关系协调性区域差异明显增强。西部省份人地关系协调性普遍降低,东、中部地区人地关系协调性有所提升,东北地区人地关系协调性保持相对稳定。目前主要表现为东部、东北及中部协调度等级较高,西部协调度等级较低的空间分布特征。3)东、中、西部地区人地关系协调性主要影响因素有所差异。各地区需根据当地自然地理条件及经济社会发展状况因地制宜,以人地协调发展为准则,结合各地区主要影响因素实施差异化的调控对策,促进人地系统的协调、可持续发展。Scientific cognition of the interactive relationship between man and land is an important basis to realize the coordinated development of the man-land relationship.In this study,the PSR(Press-State-Response)theoretical system was established to investigate the spatio-temporal pattern and the influencing factors in the coordinated development of the man-land relationship in China.Human activities posed great pressure on the regional environment and thereby aggravated the contradiction between man and land.At the same time,the man-land relationship was formed in the man-land interaction and fed back to human activities.Then,an adaptive system between man and land was formed after positive(or negative)response measures to improve(or worsen)the man-land relationship.The PSR evaluation index system was thus constructed on the basis of the theoretical system.The cross-sectional data were selected from different provinces of China in 2002,2007,2012,and 2017.The results showed that:1)There was a relatively stable level of coordinated development in the man-land relationship in China from 2002 to 2017,generally between moderate and good coordination.However,the value of coordination degree was in a V shape trend,which decreased from 0.648 to 0.494 in 2002-2007,and then rose to 0.639 in 2012,and further increased to 0.705 in 2017.There was also a development process of"tightening first and then easing"in the man-land relationship over the past 15 years.2)There was also an obvious increase in the regional differences for the coordination of man-land relations from the perspective of space.The coordination of the man-land relationship in western provinces generally decreased,and that in eastern and central regions improved,while those in northeast regions remained relatively stable.At present,it mainly showed the spatial distribution characteristics of higher coordination degree in the eastern,northeast,and central region,whereas the lower coordination degree in the western region.3)The geographic detector analysis showed th
