生态韧性视角下陕西省绿色空间的时空演变特征及其驱动机制
Characteristics of Spatial and Temporal Evolution of Green Space and Its Driving Mechanism in Shaanxi Province under the Perspective of Ecological Resilience
摘要
Abstract
Under the superimposed pressure of regional ecological degradation and rapid urbanization,ecological resilience has become an important yardstick for sustainable regional development.As the core carrier of urban ecosystems,green spaces must be systematically analyzed for their resilience evolution mechanisms.This study explored the spatial and temporal evolution characteristics of green space ecological resilience and its driving mechanism from the perspective of ecological resilience in Shaanxi Province from 2000 to 2023.Based on multi-source remote sensing and statistical data from 2000 to 2023,a three-dimensional ecological resilience assessment framework of'resistance-adaptation-resilience'was constructed for the study area,and the coupled GeoDetector and geographically weighted regression model(GWR)were used to analyze the ecological resilience of green space in Shaanxi Province.spatial and temporal evolution characteristics and driving mechanisms of green space ecological resilience in Shaanxi Province.The results showed that 1)from 2000 to 2023,the scale of green space in Shaanxi Province as a whole shrank,but the structure was significantly optimized.Among them,arable land continues to decrease(concentrated in the Guanzhong Plain),forest land increases steadily due to the policy of returning farmland to forests,and water area grows fluctuatingly due to climatic and anthropogenic regulation.2)The level of ecological resilience improves as a whole,but the spatial differentiation is significant.High-value areas were concentrated in the Qinba Mountains in southern Shaanxi(high woodland coverage and strong landscape connectivity)and the fallow forest area in southern Yan'an,whereas low-value areas were distributed in the Guanzhong Plain(fragile structure of dominant cropland)and northern Yulin(superimposed pressure of drought and energy development).3)The driving mechanism shows significant spatial differentiation.Natural factors:Precipitation enhances resilience in northern Shaanxi,whereas southern Shaanxi is at risk owing to excess water.Temperature exacerbated stress in Hanzhong,Ankang,and northern Yan'an.The slope supports resilience at the Yulin-Yan'an junction,whereas it weakens resilience in central Yan'an.Socio-economic factors:population density promotes resilience in the northern urban areas of Yulin but exacerbates vulnerability in northern Yan'an and Guanzhong(e.g.,Xi'an,Xianyang);GDP is negatively correlated in the Yulin Resource Area,with a positive effect in the Yan'an Eco-region,Guanzhong,and part of southern Shaanxi;and land-use intensity weakens resilience in the province generally and is especially pronounced in the Guanzhong area.关键词
