朝阳县“三生”空间冲突演化及其生态修复策略研究

Research on the Spatial Conflict Evolution and Ecological Restoration Strategies of the‘Three Lives’in Chaoyang County

定量探讨“三生”空间之间冲突及其演化趋势,可为国土空间管控和国土空间规划编制提供科学依据。基于朝阳县土地利用的主导功能及性质,将朝阳县土地分成生活生产空间、生态生产空间、生产生态空间和生态空间4大类型,使用景观生态指数方法构建空间冲突指数,对2010年、2020年朝阳县“三生”空间冲突的区域和强度进行识别。结果表明,2010~2020年朝阳县生产生态空间基本稳定,生态空间与生产生态空间面积增加,生活生产空间面积减少,生态空间和生态生产空间通过占用生活生产空间进行快速扩张;“三生”空间整体态势良好,冲突减弱,可控区域增加,冲突程度从大到小依次为:生态空间>生产生态空间>生态生产空间>生活生产空间。针对评价结果提出了“三生”空间生态修复策略。

Quantitative exploration of the conflicts and evolutionary trends among the ecology-production-living space can provide scientific basis for national spatial control and planning.Based on the dominant function and nature of land use in Chaoyang County,the land is divided into four types:living production space,ecological production space,production ecological space,and ecological space.The spatial conflict index is constructed using the landscape ecological index method to identify the areas and intensity of the ecology-production-living space conflicts in Chaoyang County in 2010 and 2020.The results show that from 2010 to 2020,the production ecological space in Chaoyang County was basically stable,with an increase in the area of ecological space and production ecological space,a decrease in the area of living and production space,and a rapid expansion of ecological space and ecological production space by occupying living and production space;The overall situation of the ecology-production-living space is good,with reduced conflicts and an increase in controllable areas.The degree of conflicts is in descending order:ecological space>production ecological space>ecological production space>living production space.An ecology-production-living space spatial ecological restoration strategy was proposed based on the evaluation results.
