- 摘要:
- 为识别国土空间功能类型的空间分异规律,使生产—生活—生态空间功能发挥协同效应,以南昌市为例,利用2000年、2010年、2017年3期遥感解译数据,建立基于主导功能的“三生”空间分类体系,借助土地动态度模型、空间自相关等方法,分析了南昌市“三生”空间的时空演变特征,并运用CLUE-S模型模拟了南昌市2030年不同情景下“三生”空间布局状况。结果表明:(1)2000—2017年,南昌市“三生”空间发生变化面积56 354.60 hm2,生产空间、生态空间持续减少,生活空间持续增加。(2)研究期内南昌市“三生”空间存在空间正相关关系,在镇域层面呈现出生活空间和生态空间集聚态势弱化,生产空间分布变化不明显的趋势。(3)经模拟验证,CLUE-S模型适用于南昌市未来“三生”空间分布模拟,在自然增长情境中,生产和生态空间分别减少10 310.70 hm2,11 678.79 hm2,在生态保护和耕地保护情境中,生态空间增加59 452.26 hm2,呈现出生态空间由退化到优化、生活空间由沿江逐渐扩展到其他区域的特点。
- Abstract:
- In order to identify the spatial differentiation of land spatial function types and make the production-living-ecological space function play a synergistic effectNanchang City as an example,a spatial classification system of production-living-ecological space based on the dominant function by using three remote sensing interpretation data in 2000,2010 and 2017. With the help of land dynamic degree model and spatial autocorrelation,the spatial evolution characteristics of production-living-ecological space in Nanchang City analyzed,and the spatial layout in different scenarios in 2030 simulated by CLUE-S model Status. The results show that:(1)from 2000 to 2017,the area of space changed in Nanchang was 56 139.62 hm2,the production space and ecological space continued to decrease,the living space continued to increase;(2)the study period,there was a positive spatial correlation in production-living-ecological space in Nanchang the town level,the concentration trend of living space and ecological space was weakened,and the distribution of production space was not obvious;(3)simulation results show that the CLUE-S model is suitable for the future spatial distribution simulation in Nanchang City the natural growth situation,the production and ecological space reduce by 10 310.70 hm2 and 11 678.79 hm2 respectively the ecological protection and farmland protection scenarios,the ecological space increases by 59 452.26 hm2,showing that the ecological space from degradation to optimization,and the living space gradually from along the river to other areas.
