陕西省生境质量时空演变及驱动机制分析
Spatial-temporal changes and driving factors of habitat quality in Shaanxi Province during the past 20 years
生境质量是生物多样性保护和区域生态环境改善的重要基础，生态文明建设背景下研究生境质量时空演 变及驱动机制具有重要意义。以陕西省为研究区，基于2000年、2010年和2020年的土地利用数据，利用InVEST模 型、泰尔指数和地理探测器模型分析了三大地区（陕南、陕北、关中）生境质量的时空演变特征及驱动因子。结果表 明：（ 1）2000—2020年全省平均生境质量呈现稳定且略微上升趋势，空间分布差异明显，表现为陕南和陕北地区高 于关中地区；（ 2）全省三大地区间和地区内的生境质量差异较大，陕南和关中地区差异性大于陕北地区；（ 3）受空 间尺度影响，全省和三大地区的驱动因子有所不同，植被与地形因子对全省生境质量影响最大，土地利用因子是三 大地区的主要影响因素，且随着时间推移影响程度逐渐加强，地形因子与植被因子对三大地区的影响各有不同； （ 4）除单因子影响外，社会经济与自然环境因素的协同作用对三大地区生境质量变化影响显著。

Habitat quality is an important basis for biodiversity conservation and improvement of the regional ecological environment. With an ecological civilization construction as the background, the spatial- temporal adaptation and driving mechanism of habitat quality is significant to study. Based on land use data in Shaanxi Province in 2000, 2010, and 2020, the characteristics and driving factors in the spatial-temporal adaptations of the quality of habitat in three regions were analyzed using the InVEST model, Theil index model, and geographic detector model. The results showed the following: (1) from 2000 to 2020, the average quality of habitat showed a stable and slightly increasing trend, and the spatial distribution difference was obvious, with the average habitat quality in southern Shaanxi and northern Shaanxi being higher compared to Guanzhong; (2) the difference of habitat quality among the three regions was larger in southern and central Shaanxi compared to northern Shaanxi; (3) the province and the driving factors in the three different regions, vegetation and terrain factors for the habitat quality, and land utilization factor are the main influencing factors of the three major areas affected by the spatial scale. As time goes on, the influence degree gradually strengthens, and the terrain and vegetation factors have different effects on three areas; (4) In addition to single factors, significant impacts on habitat quality changes in the three regions produced cooperative effects on socioeconomic and natural environmental factors.
