    Abstract:

    Based on the regional perspective of northwest China, the paper systematically studied the landscape characteristics, spatial distribution, protection and utilization status of Danxia landform(broad sense) in northwest China, and put forward future development countermeasures, and preliminarily discusses the protection and utilization mode of Danxia landform in northwest China. Methods: Select ninety key Danxia landforms(broad sense) 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(broad sense) in northwest China 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(broad sense) in northwest China; using the nearest adjacent index method and nuclear density analysis, the spatial structure of Danxia landform (broad sense) 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, Ganquan—Jingbian area, northern Shaanxi). 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(broad sense) resources is achieved through the combination of protection and utilization.
