借助GIS和GeoDA的技术平台,基于POI数据的加权核密度值探究十堰市2019年土地利用水平的空间分布格局;基于DEM,NDVI和土地利用类型数据构建自然与景观互补的景观生态风险评价模型;在此基础上借助双变量全局自相关模型,定量分析了其土地利用水平与景观生态风险的空间耦合关系。结果表明:(1)十堰市土地利用评价水平整体偏低,其中高、较高、较低和低等土地利用水平分别占总面积的2.5%,15.44%,58.92%和23.14%。呈现出以十堰市主城区为核心向周围递减,并在各县城心出现次高峰的空间分异规律,评价结果基本吻合其“东拓,西进、中优”的发展规划。(2)景观生态风险整体水平较低,其中高生态风险区主要分布在...

With the help of GIS and GeoDA technology platforms,based on the weighted kernel density values of POI data,we explored the spatial distribution pattern of land use levels in Shiyan City in 2019,and built a landscape ecological risk assessment model that complements nature and landscape based on DEM,NDVI and land use type data.Based on this,the spatial coupling relationship between the land use level and the ecological risk of the landscape was quantitatively analyzed with the help of a bivariate global autocorrelation model.The results show th...
