摘要:

探讨生态用地景观格局对生态空间效率的影响,对优化生态空间格局具有重要的指导意义。运用超效率SBM模型、最优参数地理探测器和多尺度时空地理加权回归等方法,分析2000-2020年贵州省生态空间效率演变特征,探究景观格局对生态空间效率的影响机理。结果表明,1)生态空间综合效率受纯技术和规模效率的共同影响,规模效率降低是导致综合效率下降及其等级结构退化的主要原因。2)20年来,三类效率的空间聚集特征不断增强,综合及纯技术效率保持着西南至东北向南一侧效率较高,靠北一侧效率较低的空间分布格局,规模效率演变为贵州中部和东部效率较高、西部和南部效率较低的空间分布格局。3)景观格局指数主要是通过影响规模效率进而作用于综合效率,各景观格局指数在空间上对规模效率的影响存在显著差异且具有不同程度的时空异质性,河流水系的保护配合形态规整的多团块、优连通的生态用地布局模式有利于规模效率的提升。4)规模效率并非受各景观格局指数的独立影响,而是两两交互作用下产生双因子增强和非线性增强的综合结果,作为主导影响因子的LSI与其他指数的交互协同作用是造成规模效率出现空间分异的主要力量。对生态空间优化时,应根据不同单元效率的高低差别、分布格局及各指标的影响差异精准施策,促进生态环境提质增效。

Abstract:

Understanding the influence of ecological land landscape patterns on ecological space efficiency is crucial for optimizing ecological spatial layouts. This study integrated the Super-Efficiency Slacks-based Measure model, Optimal Parameter-based Geographical Detector and Multi-scale Geographically and Temporally Weighted Regression to analyze the evolution characteristics of ecological space efficiency in Guizhou Province during 2000-2020 and explore the underlying mechanisms of ecological land landscape patterns on ecological space efficiency. The results showed that 1) the comprehensive efficiency of ecological space was jointly determined by pure technical efficiency and scale efficiency; however, the decrease in scale efficiency was the main reason for the decline in comprehensive efficiency and the degradation of its hierarchical structure. 2) From 2000 to 2020, the spatial aggregation characteristics of ecological spatial comprehensive efficiency, pure technical efficiency, and scale efficiency in Guizhou Province continuously improved. The comprehensive efficiency and pure technical efficiency maintained the spatial distribution pattern of higher efficiency in the south from southwest to northeast and lower efficiency in the north. The scale efficiency evolved into a spatial distribution pattern of higher efficiency in the eastern and central regions and lower efficiency in the western and southern regions. 3) Landscape pattern indices mainly influence scale efficiency and subsequently influence comprehensive efficiency. The influences of these indices on scale efficiency were significantly different, and there were different degrees of spatial and temporal heterogeneity in the results of the study. To protect the river system, the layout model of ecological land with a regular shape, multi-blocks, and excellent connectivity was conducive to improving ecological space scale efficiency in Guizhou Province. 4) Ecological space scale efficiency was not independently influenced by each landscape pattern index, but two-factor and nonlinear enhancements were produced by the interaction of two factors. Landscape Shape Index, as the dominant influencing factor, interacted with other independent factors and was the dominant force that caused spatial differentiation of scale efficiency. When optimizing ecological space, precise policies should be implemented according to the efficiency differences of different units, distribution patterns, and influence differences of various indicators to improve the quality and efficiency of the ecological environment.
