Spatial and Temporal Evolution of Habitat Quality in Mountainous City Based on Land Use Transition and Its Driving Factors——A Case Study of Sanming city
摘要
Abstract
This study analyzed the spatial and temporal evolution of land use transformation characteristics and habitat quality in Sanming City from 2000 to 2020 by ArcGIS and InVEST models.Combined with the calculation of the contribution rate of habitat quality,the impact of the transformation of various land types on habitat quality was quantified and compared.Geodetector was used to analyze the driving forces of habi-tat quality in the study area to deeply explore the main factors affecting habitat quality.The results showed that 1)forests consistently occupied the largest area ratio among land use types in Sanming from 2000 to 2020,both exceeding 70％of the total area.More significant land use transition occurred from 2010-2020.2)The average habitat quality indices of Sanming in 2000,2010 and 2020 were 0.806 49,0.806 54,and 0.774 88,respectively,and the overall level of habitat quality was at a high level.3)Habitat quality in San-ming presented obvious spatial clustering characteristics,with regional clustering of high quality habitats and regional clustering of low quality habitats as the main clustering characteristics.4)Conversion of crop-land,grassland,and man-made surfaces to forest was the main reason for habitat quality enhancement,con-version of forest to cropland,grassland,and man-made surfaces,and conversion of cropland to man-made surfaces were the main reasons for habitat quality reduction.5)In the analysis of habitat quality driving factors,the total influence of the natural environment-related factors was higher than that of the social-re-lated factors,and the influence of NDVI was the highest among the eight factors.The influence of any com-bination of two factors on habitat quality was higher than that of a single factor.The results strengthen the knowledge of spatial and temporal variation of habitat quality in mountainous cities and have theoretical and practical values for promoting the conservation of biodiversity and the construction of ecological civili-zation.关键词
