In the process of rapid change of the " Agricultural-Urban-Ecological Space " of the national land,namely urban space,agricultural space(agricultural production space,rural living space),and ecological space(green ecological space,other ecological space),the squeeze between spatial multi-functions makes the development of various types of spaces unbalanced.With the proposal of "three districts and three lines" in territorial spatial planning,the orderly development of regional functional spaces is an important part of the coordinated development of space in the near future.Based on the basic theories of regional spatial structure theory,sustainable development theory,human-land relationship theory,spatial conflict theory,etc.,this article uses the land use status data from 2009,2014,2019,etc.,the land use primary and secondary function identification method and the transfer matrix method to analyze the dynamic change characteristics of the distribution of "Agricultural-Urban-Ecological Space".The spatial conflict measurement model was constructed by the landscape ecological index method,and the spatial autocorrelation analysis method was used to analyze the characteristics of the " Agricultural-UrbanEcological Space " using the conflict change method with the help of Google Earth software.The geographic detector model was used to analyze the influence factors of spatial conflict from the perspectives of natural conditions and socio-economic conditions.The PLUS model is used to construct the conflict state of the " Agricultural-Urban-Ecological Space " pattern under three scenarios: 2029 benchmark scenario,cultivated land protection scenario and ecological protection scenario,and then put forward pattern optimization countermeasures and suggestions.The main conclusions are as follows:(1)From 2009 to 2019,other ecological spaces and green ecological spaces showed a decreasing trend,while urban space,agricultural production space and rural living space showed an increasing trend,and the overall trend was "two minus three increase".The green ecological space was mainly distributed in the central area of the study area,the southern area of Ulanchabusumu and the south-central area of Yihenaursumu.Other ecological spaces were scattered in clumps,mainly concentrated in the northern part of the study area,and the northern area of Ihonaursumu and Baolagentaohaisumu.The agricultural production space area was distributed in a polygonal cluster,mainly distributed in Xingyao Town,in the southwest area of the study area.The urban space and rural living space are scattered in clusters,mainly concentrated in the southern area of the study area,and the town of Ming’antu and the Taohai Sumu area along the Baolagen Taohai Sumu are developed in the transportation area.(2)The " Agricultural-Urban-Ecological Space " conflict value is relatively weak,concentrated between 0.2-0.4.Based on the interval breakpoint method,the spatial conflict value is divided into weak spatial conflict value [0-0.2],which is the complete control stage of spatial conflict;The weak spatial conflict value [0.2-0.4] is the basic control stage of space conflict;The medium spatial conflict value [0.4-0.6] is the manifestation stage of spatial conflict;The strong spatial conflict value [0.6-0.8] is the transition stage of space conflict;The powerful spatial conflict value [0.8-1] is the spatial conflict glue stage.From 2009 to 2019,there was a strong space conflict out of control area in Ming’antu Town,the research area,and there was a trend of expanding the scope,which may be the key area for the regulation of space conflict in this area.The study area is dominated by weak space conflicts,especially in Ulanchabusumu,Yiheersumu Mingantu Town,Zherigen Tu Forest Farm,and Baolagen Taohaisumu,which are in the stage of basic control of space conflicts and external influences are stably controlled.Medium space conflicts are mainly distributed in Xingyao Town and Elitu Breeding Farm,which is in the emerging stage of space conflicts,and the external influences are basically controllable,which is a key stage of management and prevention.From 2009 to 2019,from the perspective of the evolution of multifunctional space conflicts in the study area,green ecological space,other ecological space conflicts,rural living space,and urban space were mainly weak spatial conflicts,and external influences could be stably controlled,and they were in the basic control stage of space conflicts.The agricultural production space is dominated by strong spatial conflicts,which is in the transformation stage of spatial conflicts,and the external influences are basically out of control.(3)From the perspective of natural conditions and socio-economic conditions,the spatial conflict distribution in the study area was mainly affected by land use comprehensiveness,population density and soil type,while the spatial conflict in Ming’antu Town and Xingyao Town was most affected by land use comprehensiveness,population density and soil type,while the other townships(Sumu)had less influence.From 2009 to 2019,the interaction of impact factors in the whole area of the study area showed two-factor enhancement and nonlinear enhancement.(4)Based on spatial conflict evaluation and conflict impact factor analysis simulation prediction,it is set as three development scenario models: benchmark scenario,cultivated land protection scenario and ecological protection scenario.Through the spatial conflict analysis of the three development scenario models,combined with policy,territorial spatial planning,local development and other aspects,the targeted pattern optimization suggestions of the development of the three scenarios are proposed. |
