摘要:
城市建设用地的扩张一直是影响城市生态系统的主要因素,山地城市因其复杂、敏感的自然环境特征,生物多样性更容易受到冲击. 因此,深入分析山地城市的生境质量是改善当地生境质量、保护生物多样性的必要措施. 本次研究选用InVEST模型对三明市区2011、2021年的生境质量进行模拟测算,评估三明市区范围的生境等级,结合地形位指数分析生境质量的梯度效应; 运用地理探测器对研究区内的生境质量进行驱动力分析,探寻影响生境质量的主要因素. 结果表明:(1)2011、2021年三明市区的平均生境质量指数分别为0.539 9、0.595 3,生境质量水平总体处于中上水平,空间上呈现出外高内低的现象.(2)三明市区的生境质量展现出明显的空间集聚特征,以高质量生境区域集聚和低质量生境区域集聚作为主要集聚特征.(3)三明市区的生境质量分布指数具有显著的地形位梯度效应,高生境质量在高地形梯度有绝对优势,低生境质量在低地形位梯度上有绝对优势.(4)在研究区域的生境质量驱动力分析中,自然环境的影响高于社会因素. 研究结果加强了对山地城市生境质量时空变化的认知,对三明市区生境质量提升与保护具有一定的理论与实践价值.
Abstract:
The expansion of urban construction land had always been the main factor affecting the urban ecosystem. Due to its complex and sensitive natural environment,mountain cities were more vulnerable to the impact of biodiversity. Therefore,in-depth analysis of the habitat quality of mountain cities were a necessary measure to improve local habitat quality and protect biodiversity. In this study,the InVEST model was used to simulate and calculate the habitat quality of the urban area of Sanming in 2011 and 2021,to evaluate the habitat level of the urban area of Sanming,and to analyze the gradient effect of the habitat quality in combination with the terrain level index. The driving force analysis of the habitat quality in the study area was carried out by using geodetector,and the main factors affecting the habitat quality were explored. The results showed that,(1)The average habitat quality index in Sanming urban area in 2011 and 2021 was 0.539 9 and 0.595 3,respectively. The habitat quality level was generally at the upper-middle level,showing a phenomenon of high outside and low inside.(2)The habitat quality in the urban area of Sanming showed obvious spatial agglomeration characteristics,with regional agglomeration of high-quality habitats and regional agglomeration of low-quality habitats as the main agglomeration characteristics.(3)The habitat quality distribution index in the urban area of Sanming has a significant terrain gradient effect. High habitat quality had an absolute advantage in high terrain gradient,and low habitat quality had an absolute advantage in low terrain gradient.(4)In the driving force analysis of habitat quality in the study area,the influence of natural environment was higher than that of social factors. The research results strengthen the cognition of the temporal and spatial changes of the habitat quality of mountain cities,and had certain theoretical and practical value for the improvement and protection of the habitat quality in Sanming urban area.
