摘　　要：为探究南山国家公园生境质量变化及驱动机制,运用InVEST和地理探测器模型对南山国家公园2000-2020年生境质量进行评估,通过生境质量空间分异特征分析。结果表明:①南山国家公园整体生境质量在空间上呈现出“东部高、西部低”的分布格局,2000年、2010年、2020年生境质量分别为0.646、0.561、0.647,呈现先减少后增加的趋势;②南山国家公园生境质量在空间上具有较强的空间集聚特征,研究区生境质量变化分布较为集中,且热点区相较于冷点区更为明显;③降雨是影响南山国家公园生境质量的主要驱动因子。从驱动因子交互作用来看,各驱动因子交互增强效果显著,增强以非线性为主,双因子增强次之。主要为降雨、高程和气温与其他驱动因子间交互作用较强,其中以降雨与各驱动因子间交互效果最明显。研究结果可为南山国家公园规划建设和生态保护格局提供参考。In order to explore the changes and driving mechanism of habitat quality in Nanshan National Park,InVEST and geo-detector models were used to evaluate the habitat quality of Nanshan National Park from 2000 to 2020,and the spatial differentiation characteristics of habitat quality were analyzed.The results showed that:①the overall habitat quality of Nanshan National Park showed a spatial distribution pattern of'high in the east and low in the west'.The habitat quality in 2000,2010 and 2020 was 0.646,0.561 and 0.647,respectively.It shows a trend of decreasing first and then increasing;②the habitat quality of Nanshan National Park has strong spatial agglomeration characteristics.The distribution of habitat quality changes in the study area is relatively concentrated,and the hot spot area is more obvious than the cold spot area;③rainfall is the main driving factor affecting the habitat quality of Nanshan National Park.From the perspective of the interaction of driving factors,the interaction enhancement effect of each driving factor is significant,and the enhancement is mainly nonlinear,followed by two-factor enhancement.The interaction between rainfall,elevation and temperature and other driving factors is strong,and the interaction between rainfall and each driving factor is the most obvious.The research results can provide theoretical basis and decision support for the planning,construction and ecological protection pattern of Nanshan National Park.
