摘要:

基于2000年、2005年、2010年、2018年山西省107个县区数据,构建山西省高质量发展评价指标体系,使用InVEST模型测算山西省各县区生态系统服务,利用耦合协调度模型与弹性系数方法,对山西省县域高质量发展系统与生态系统服务的时空耦合特征进行剖析。结果表明:(1) 城市的等级效应对于高质量发展水平影响效果显著,高质量发展的空间分异规律较强,大致形成了南北中三级核心,中部地区极化效应突出。(2) 生态系统服务在时间尺度和空间格局上均具有锁定效应,时空演变特征与研究区地形分布具有一致性,呈现出稳定的“镜像L型”空间分布格局。(3) 生态系统服务整体滞后于高质量发展,从时间变化来看,耦合水平呈上升趋势,从空间格局特征来看,呈现出“东西向”偏移为“东北-西南”的协调主体轴。(4) 高质量发展与生态系统服务的耦合类型以异向变化为主,出现衰退型和滞后型相抗衡的“两极分化”格局,形成了收敛的“S”型衰减区,作为耦合类型的理想模式,增长型在研究区极少出现。

Abstract:

Based on the data of 107 counties and regions in Shanxi Province in 2000, 2005, 2010, and 2018, this paper constructs the evaluation index system of high-quality development in Shanxi Province, uses the InVEST model to calculate the ecosystem services of counties and regions in Shanxi Province, and analyzes the spatiotemporal coupling characteristics of the high-quality development system and ecosystem services of counties in Shanxi Province by using the coupling coordination model and elasticity coefficient method. The following results are presented. (1) The grade effect of cities has a significant impact on the level of high-quality development. The spatial differentiation law of high-quality development is strong, which roughly forms the north-south-middle three-level cores, and the polarization effect in the central region is prominent. (2) Ecosystem services in the study area have locking effects in time scale and spatial pattern. The temporal and spatial evolution characteristics are consistent with the topographic distribution of the study area, showing a stable “mirror L-shaped” spatial distribution pattern. (3) Ecosystem services in the study area generally lag behind high-quality development. From the perspective of the time change, the coupling level shows an upward trend. From the perspective of spatial pattern characteristics, ecosystem services and the high-quality development show the coordination main axis of “northeast-southwest.” (4) The coupling type of high-quality development and ecosystem services in the study area mainly changes in different directions, generally showing a retrogressive development trend. A “polarization” pattern, in which recession and lag types compete, is also observed, forming a convergent “S” type attenuation area. As an ideal model of coupling type, growth type is remarkably few in the study area.
