摘要
以呼包鄂榆城市群为研究对象,基于2000-2020年土地利用数据,利用InVEST模型对其生境质量的时空变化特征进行分析,使用空间自相关分析其空间集聚效应,并进一步利用地理探测器对其影响因子进行分析。结果表明:1)呼包鄂榆城市群的土地类型以草地、耕地、未利用地为主。研究区各地类之间的主要变化方向为草地、耕地以及未利用地向建设用地与林地转换;2)呼包鄂榆城市群生境质量空间区域差异较为明显,且与当地土地利用类型高度对应,其中东部的生境质量优于西部,北部的生境质量优于南部;3)20 a间,研究区较低级与中等等级的生境质量区域面积减少,低级、较高级与高级区域面积增加,呈现两极分化特征。研究期内,该区域生境质量具有较好的空间集聚性且空间集聚性比较稳定;4)呼包鄂榆城市群生境质量受到自然地理因素以及社会经济因素的共同作用,其中,温度、降水以及人口因素是影响研究区生境质量的核心因子。研究区应自觉遵守自然因素的限制,实行生活方式与经济发展模式低碳转型,并在此基础上减少水资源污染以及大气污染,维持正常的水文循环,严守生态红线,减少人类活动对生态环境的影响。
Habitat quality can be quantitatively analyzed to show the capability that the ecological environment of the study area can provide human survival and development.Based on the land use data from^(2)000 to 2020,the InVEST model was used to analyze the temporal and spatial change characteristics of the habitat quality of the Hohhot-Baotou-Ordos-Yulin Urban Agglomeration,and the spatial autocorrelation was used to analyze its spatial agglomeration effect.The influence factors were analyzed by using the geographical detector.The results were as follows.1)Grassland,cultivated land and unused land were the main land types in the region.The main direction of change among different classes in the study area was the conversion of grassland,cultivated land and unused land to construction land and forest land.2)The spatial difference of habitat quality in the region was obvious and highly correlated with local land use types.The habitat quality in the east was better than that in the west,and that in the north was better than that in the south.3)During the past 20 years,the areas of lower and middle grades of habitat quality in the study area decreased,while the areas of lower,higher and highest grades increased,showing the features of polarization during the study period.The habitat quality in this region had good spatial agglomeration and the spatial agglomeration was relatively stable.4)The habitat quality of the region was influenced by natural geographical factors and socio-economic factors.Among them,temperature,precipitation and population factors were the core factors that affected the habitat quality in the study area.The study area should consciously abide by the limitations of natural factors,implement the low-carbon transformation of lifestyle and economic development mode,and on this basis reduce water resources pollution and air pollution,maintain the normal hydrological cycle,strictly observe the ecological red line,and reduce the impact of human activities on the ecological environment.
