| 以滇中地区为研究区域，采用DPSIR、障碍度、耦合协调度模型对2012—2022年滇中地区土地生态安全与经济发展的耦合协调关系进行分析。结果表明：2012—2022年滇中地区土地生态安全呈现倒“V”型波动，安全等级由临界状态（Ⅳ）升至安全（Ⅱ）又下降到较安全（Ⅲ），空间分布呈现“中部高、四周低”逐渐向“中部低、两侧高”的变化趋势，区内障碍度较大子系统为驱动力和状态子系统。2012—2022年滇中地区经济发展综合指数总体呈现上升趋势，平均年增长率为154%，土地生态安全与经济发展耦合协调等级由接近协调（Ⅴ）上升到良好协调（Ⅱ），空间分布呈现“中部高、四周低”向“中部低、四周较高”的变化趋势。 |

| Taking the central Yunnan region as the study area， this paper employed DPSIR model， obstacle degree model and coupling coordination degree model to analyze the coupling coordination relationship between land ecological security and economic development in central Yunnan region from 2012 to 2022. The results showed that from 2012 to 2022， the land ecological security in central Yunnan region exhibited an inverted “Ⅴ” shaped fluctuation， with the security level rising from critical state (Level Ⅳ) to safe (Level Ⅱ) and then declining to relatively safe (Level Ⅲ). The spatial distribution showed a gradual shift from a pattern of “high in the center and low in the periphery” to “low in the center and high on both sides”. The subsystems with a relatively high obstacle degree in the region were the driving force subsystem and the state subsystem. From 2012 to 2022， the comprehensive economic development index of central Yunnan region showed an overall upward trend， with an average annual growth rate of 154%. The coupling coordination level between land ecological security and economic development rose from close to coordination (Level Ⅴ) to good coordination (Level Ⅱ)， and the spatial distribution showed a changing trend from “high in the center and low in the periphery” to “low in the center and relatively high in the periphery”. |
