摘要:
黄土高原是我国重要的生态屏障区,开展三生空间研究对推进该地区的生态文明建设具有重要意义。基于土地利用数据,构建了生产-生活-生态空间功能性土地分类体系,揭示了1980—2018三生空间格局分布及演变特征,应用地理探测器分析了三生空间变化的驱动因子。结果表明:(1)黄土高原地区主要以生态空间为主体,生产空间主要聚集于东南部,生活空间集中于快速发展的重要城市,生态空间主要分布于西部及中部地区。(2)生产和生态空间在黄土高原的中西部地区的变化均较为剧烈,生活空间的扩张主要集中在各大城市。(3)社会经济因素对三生空间的演变有较为显著的影响。人口是影响生产空间面积变化的主要因素;农林牧渔业总产值对于生活空间面积的限制作用较强;财政收支对生态空间的解释力较强。这些因子之间的交互作用对三生空间的影响都大于单个因素。结果能够为未来黄土高原地区生态系统持续健康发展提供良好的借鉴,并为推进三生空间协调发展提供决策参考。

Abstract:
The Loess Plateau is an important ecological screen in China. It is of great significance to conduct ecological-production-living (EPL) research so as to promote the ecological civilization construction in the region. Based on the land use data, a functional land classification system for EPL space was constructed, revealing the spatial pattern distribution and evolution characteristics from 1980 to 2018, and the driving factors of EPL space spatial changes were analyzed by using geographical detector model. The results showed that: (1) The ecological space was the main body in the Loess Plateau; the production space was mainly concentrated in the southeastern part of the region; the living space was concentrated in the rapidly developing cities, and the ecological space was mainly distributed in the western and central parts of the region. (2) The changes of production and ecological space in the central and western parts of the Loess Plateau were more dramatic, and the expansion of living space was mainly concentrated in the major cities. (3) Socio-economic factors had significant impacts on the evolution of EPL space, and the population was the main factor affecting the change of production space; gross output value of the agriculture, forestry, animal husbandry and fishery had a strong restrictive effect on the living space, while fiscal revenue and expenditure had a strong explanatory power for ecological space, and the interaction between these factors had a greater impact on the EPL spaces than a single factor. The results could provide a model for the sustainable and healthy development of ecosystem in the Loess Plateau in the future and a reference for the decision-making of promoting the coordinated development of EPL space.
Key words:  the Loess Plateau  EPL space  gini coefficient  geographical detectors model
