基于参数最优地理探测器的福州市生境质量时空格局与驱动力分析

揭示生境质量的时空演变特征和影响因素可为区域可持续发展提供参考依据。基于2000年、2010年和2020年的土地利用数据，运用InVEST模型、土地利用转移矩阵和参数最优地理探测器等方法，综合分析福州市生境质量时空演变及其驱动因素。结果表明：福州市2000年、2010年和2020年生境质量指数分别为0.812、0.806和0.793，生境质量改善的面积小于生境质量退化的面积，福州主城区和东南沿海区域的生境状况亟须改善。3 km网格为本研究的最佳空间尺度，最佳数据离散化分类数为6，自然间断点法更能解释驱动因素的驱动程度。高程、坡度和夜间灯光是福州市生境质量空间分异的主要影响因素，坡度和夜间灯光的交互作用对生境质量变化的解释力最强。

Analysis of spatiotemporal heterogeneity of habitat quality and their driving factors based on optimal parameters-based geographic detector for Fuzhou City,China

Revealing the spatiotemporal evolution characteristics of habitat quality and their influencing factors can provide reference basis for regional sustainable development. Based on the land use data in 2000, 2010 and 2020, InVEST model, landuse transfer matrix and optimal parameters-based geographical detector (OPGD) were used to comprehensively analyze the spatiotemporal evolution and driving factors of habitat quality in Fuzhou City. The results revealed that the habitat quality index of Fuzhou City in 2000, 2010 and 2020 was 0.812, 0.806 and 0.793, respectively. The area of habitat improvement was less than the area of habitat deterioration. Habitat conditions in the main urban area of Fuzhou and the southeast coastal region were in urgent need of improvement. 3 km was the best optional spatial unit for this study, the optimal data discretization classification number is 6, and the natural break method better explained the explanatory power of the driving factors. Elevation, slope and night-time lights were the main influencing factors of spatial variation in habitat quality in Fuzhou City, and the interaction of slope and nighttime lights had the strongest explanation for habitat quality changes.
