中国西北地区丹霞地貌景观特征、空间分布及保护利用初探

本文选取中国西北地区90处重点丹霞地貌（广义）地质遗迹为研究对象，对选取的遗迹进行景观特征分析，并采用Arc GIS进一步探讨其空间分布特征。我国西北地区丹霞地貌的整体空间分布，呈西北—东南方向“L形”分布，本文运用最邻近指数法和核密度分析法，得出其空间结构类型为集聚型，并形成5个高密度区。目前，研究区存在保护利用家底不清、顶层设计匮乏等问题，未来应通过建立丹霞地貌脆弱性评价和措施体系，推进世界丹霞地质遗迹品牌和IP建设等途径，探讨西北地区丹霞地貌（广义）保护利用的具体方式。

Discussion on the landscape characteristics, spatial distribution and protection and tilization of Danxia Landform in Northwest China

Based on the regional perspective of northwest China, the paper systematically studied the landscape characteristics, spatial distribution, protection and utilization status of the Danxia Landform(broad sense) in northwest China, and put forward a few future development countermeasures, and preliminarily discusses the protection and utilization mode of the Danxia Landform in northwest China.Methods: Select ninety key Danxia landforms in northwest China, and conduct spatial analysis by Arc GIS based on the geological structure map, use the system to analyze the spatial structure of the locations, the strata, the main landscape types, and the protection and utilization status.Results: In terms of spatial distribution, the Danxia Landform in northwest and the spatial structure of Danxia Landform in northwest is agglomeration, forming five high density areas (Xining Yellow River Basin, Longdong loess plateau area, Linxia-Lanzhou-Baiyin area, Zhangye-Jiayuguan area, and the northern Shaanxi Ganquan-Jingbian area). The loess covered Danxia exists in northwest China, the most typical in Gansu Province and Shaanxi Province; both positive and negative landforms, colorful hills, slit canyons and wave valley type Danxia; Danxia cliff is mostly combined with religious art.Conclusions: The loess covered Danxia exists in northwest China, the most typical in Gansu and Shaanxi provinces; both positive and negative landforms, narrow valleys, wave valley Danxia; Danxia cliffs combined with religious art. In terms of spatial distribution, the Danxia landform in northwest China; using the nearest adjacent index method and nuclear density analysis, the spatial structure of Danxia landform in northwest China is concentrated, forming five high-density areas (Xining Yellow River Basin, Longdong Loess Plateau Area, Linxia-Lanzhou-Baiyin Area, Zhangye-Jiayuguan Area, Northern Shaanxi Ganquan-Jingbian Area). At present, the northwest danxia landform protection using money is not clear, lack of top-level design, danxia brand and IP image has not been established, the future should establish danxia landform vulnerability evaluation and measures system, intensify scientific research, promote the world danxia geological relics brand and IP construction, promote the construction and development of geological culture village danxia landform ecological tourism and studies tourism.The integration of Danxia landform resources is achieved through the combination of protection and utilization.
