摘　　要：评估生境质量时空变化,为生物多样性保护和资源合理利用提供参考。以贵州省麻江县省道S309为例,基于1992年、2012年土地利用数据,利用InVEST模型对1992～2012年公路沿线生境质量变化进行分析。结果表明：1992～2012年,耕地和未利用地面积减少,有林地、灌木林、草地、城镇工矿用地、农村居民点和水域面积增加。10年间,省道S309公路麻江段沿线生境质量指数增加0.07,公路东、西段生境质量高于中段,各坡度和距离梯度带生境质量均呈增加趋势。城镇化、退耕还林还草工程、地形等是影响山区公路沿线生境质量变化的重要因素。Exploring the spatial-temporal change of habitat quality will provide a scientific reference for biodiversity protection and reasonable utilization of resources. Taking 309 provincial road in Majiang county of Guizhou province,the study analyzed the habitat quality change along the road in mountainous from 1992 to 2012 utilizing InVEST model based on land use data for 1992 and 2012. Cultivated land and unused land area decreased while forestland,shrub,grassland,urban and industrial land,rural settlements and water body area increased from 1992 to 2012. Habitat quality along 309 provincial road in Majiangcountyincreased by 0. 07 from 1992 to 2012. Habitat quality in east and west parts of road was greater than central part. Habitat quality increased in slope and distance gradients. Urbanization,Green for Grain Project and terrain are important factors affecting habitat quality changes along the road in mountainous.
