Study on the Infrastructure of the “Plateau Water and Grass Gallery” in Aba Prefecture Based on Nuclear Density Analysis

Aba is renowned for its rich and unique tourism resources such as water, grass and snow-capped mountains. In recent years, Aba has been developing its tourism industry at a high rate with the creation of a national all-area tourism demonstration area as the main line, but the lack of infrastructure has long restricted the high-quality development of its cultural tourism. With the creation of Ruoerge National Park approved, Aba urgently needs a more precise positioning in order to build a national model area for tourism and an international ecological and cultural tourism destination. This paper proposes a tourism plan of “Plateau Water and Grass Gallery” and identifies and analyses the five types of POI data and traffic network data clusters related to tourism in Aba Prefecture through ArcGIS. The research concludes that the level of infrastructure does not match; the distribution of scenic spots is concentrated; and the development of the region is unbalanced. Accordingly, countermeasures are proposed in three aspects: complementing transportation, improving supporting facilities and upgrading scenic spots, in order to promote the construction of the water and grass gallery and the high-quality development of the whole area of tourism.
