基于"大气质量-气候因子-土地利用类型"的京津冀酸枣适生区分布研究
Study on the Spatial Distribution of Ziziphus jujuba Mill.var.spinosa Resources in Beijing-Tianjin-Hebei Region Based on"Atmospheric Quality-Climatic Factors-Land Use Type"
摘要
Abstract
Objective To explore the ecological suitability of Ziziphus jujuba Mill.var.spinosa(Bunge)Hu ex H.F.Chou in Beijing-Tianjin-Hebei region by coupling the multi-dimensional datasets of"atmospheric quality-climate factors-land use type".Methods Based on the sample sites of Ziziphus jujuba Mill.var.spinosa actually collected in the Beijing-Tianjin-Hebei region from 2020 to 2024,and combining 19 contemporary climate factors,6 atmospheric quality factors,and 14 soil attribute factors and land use types,the MaxEnt model was used to reveal the key environmental factors affecting the growth of Ziziphus jujuba Mill.var.spinosa,and to clarify its ecologically suitable area in Beijing-Tianjin-Hebei region.Results The main environmental factors affecting the distribution of sour jujube were PM10,O3,monthly mean diurnal temperature difference,and isothermality,etc.Moreover,the high suitable areas for Ziziphus jujuba Mill.var.spinosa in Beijing-Tianjin-Hebei region was the mountainous zone of Xingtai,Shijiazhuang,Baoding and Handan,which accounted for 45.21%of the total area of suitable area in Beijing-Tianjin-Hebei region.The main low-fitness areas were Zhangjiakou,Cangzhou and Hengshui.The main land use types in the high suitability zone were dryland,high cover grassland and medium cover grassland.Conclusion This study indicates that the contribution of climatic factors and atmospheric quality factors is higher than that of soil property factors,which will provide references for the conservation,sustainable development and utilization of Ziziphus jujuba Mill.var.spinosa in Beijing-Tianjin-Hebei region.关键词
