摘要: 山西中部盆地城市群是山西省的人口经济密集区,其三生空间格局受人类影响显著,引发的景观生态风险变化值得关注。本文基于1980、2000、2010和2018年土地利用数据,按照主导功能划分三生空间,分析三生用地的数量增减及类型转移情况;利用景观指数构建生态风险评价模型,定量测算区域风险程度;运用格网GIS、空间自相关、克里金插值等方法,综合展现景观生态风险的分布聚类特征和时空格局演变,并探究其成因。结果表明:研究区以农业生产空间为主,其面积逐年减少,主要转移流出为城乡生活和工矿生产空间;林地和草地生态空间占比高,相互转移频繁;城镇、农村生活和工矿生产空间受其他类型转入,规模显著扩大,较初期增加1216.75 km2。研究区三生空间与景观生态风险具有关联性;城镇生活空间是低风险区,林地风险较低,草地为中风险等级,农村生活、农业生产、工矿生产空间在盆地内形成较高风险区,水域和其他生态空间的风险最高;景观生态风险的空间自相关性强,高高和低低集聚格局明显。研究区1980—2018年景观生态风险总体呈上升趋势,较高和高风险区面积增加,所占比例共提高6.47%,且各风险区多向更高一级转变;2000—2010年是城镇化快速推进期,三生空间增减转型变化幅度大,全区景观生态风险指数平均值由0.3042增加至0.3140。

Abstract: The urban agglomeration in the central basin of Shanxi is a densely populated and economic area. The spatial pattern of the “production-living-ecological spaces” of the agglomeration is significantly influenced by humans and trigger changes in landscape ecological risks, which deserves more attention. Based on the land use data in 1980, 2000, 2010 and 2018, the whole region was divided into production-living-ecological spaces according to their dominant functions, aiming to analyze the increase and decrease of the area and the situation of land type transformation in three types of space. An ecological risk evaluation model was constructed by the landscape index to quantitatively measure the degree of regional risk. Using the methods of grid GIS, spatial autocorrelation, and Kriging interpolation, we comprehensively explored the distribution and clustering characteristics and the spatial-temporal pattern evolution of landscape ecological risks, as well as the driving factors. The area of the region was dominated by agricultural production space, which was decreasing year by year and mostly transferred to urban-rural living and industrial mining production spaces. Woodland and grassland ecological spaces took high proportions and were frequently transferred to each other. The area of urban, rural living and industrial mining production spaces transferred from other types were significantly expanded, with 1216.75 km2enhancement compared with the initial period. The production-living-ecological spaces in this region were correlated with the landscape ecological risk. Urban living space was at a low risk. Woodland was at a lower risk. Grassland was at medium risk level. Rural living, agricultural production and industrial mining production spaces formed a higher risk area in the basin. Waters and other ecological spaces had the highest risk. The spatial autocorrelation of landscape ecological risk was strong, with obvious highhigh and low-low clustering patterns. The overall trend of landscape ecological risk in the region from 1980 to 2018 was upward, as indicated by the facts that the proportion of area with higher and high risk was totally increased by 6.47% and that each risk area mostly shifted to a higher level. In the period of rapid urbanization from 2000 to 2010, there was a large change in the transformation of production-living-ecological spaces, and the average value of landscape ecological risk index increased from 0.3042 to 0.3140.
