通过土地利用变化研究区域"三生空间"时空变化与耦合协调度,对于区域是否可持续发展有着重要的参考意义.采用PLUS-Markov模型,基于赣州市 2000、2010 和 2020 年的土地利用数据,对 2030 年的土地利用情况进行预测,并引入耦合协调模型,研究和分析该地区"三生"空间发展协调度的时空变化趋势展开纵向分析,同时对 18 个县市区进行横向分析对比.研究表明:1)预计 2030 年将比 2000 年生产功能总分值增加1.04%,生活功能总分值增加 155.46%,生态功能总分值下降 1.43%.2)2000-2030 年,赣州市地区整体协调度均处于严重失调状态,但随着时间的推移,严重失调区域占比逐渐下降,在 2010 年后,高度协调度区域的占比快速上升.3)在 18 个县市区中,章贡区和南康区"三生空间"协调度明显优于其他县市区,定南县和崇义县较为落后.4)赣州市高林地覆盖率的特性,意味着其生态空间分布较广及生态功能较强,但在研究期间,建设用地的扩张并未导致"三生空间"协调发展的失衡,反而促进了其良好的协调发展.
Research on the Spatial Coupling Harmonious Degree Spatial-Spatial Evolution of "Production-Living-Ecological Space" in Ganzhou Based on PLUS-MarKov Prediction Model
The research of spatial-temporal change and coupling harmonious degree of regional"Production-Living-Ecological space"through land use change has important reference signifi-cance for the sustainable development of the region.This paper uses the PLUS-Markov model to simulate and predict the land use situation in 2030 based on the land use data of 2000,2010 and 2020,and introduces the coupling harmonious degree model to study and analyze the spatial-tempo-ral change of the coordination degree of"Production-Living-Ecological"spatial development in Ganzhou city.At the same time,we carry out a longitudinal analysis of the change trend,and a hor-izontal analysis and comparison of 18 counties and urban areas.The simulation shows that between 2000 and 2030 the total score of production function will increase by 1.04%,the total score of life function will increase by 155.46%,the total score of ecological function will decrease by 1.43%.The coupling harmonious degree change of 2000-2030 shows that the overall coordination degree of Ganzhou city was in a state of serious imbalance,but the proportion of areas with severe imbalance gradually decreased over time,and the proportion of areas with high coordination degree rapidly in-creased after 2010.Among the 18 counties and urban areas,Zhanggong district and Nankang dis-trict have significantly better coordination degree than other areas of Ganzhou city,while Dingnan county and Chongyi county are relatively backward.The characteristics of high forest land coverage in Ganzhou means that its ecological spatial distribution is wide and its ecological function is strong,but the expansion of construction land during the study period did not lead to the imbalance of the coordinated development,on the contrary,promoted its good coordinated development.
