Abstract:
The Xinyang section of the Huaihe River Basin was selected as the study area, nuclear density analysis and standard deviation ellipse model were used to analyze the spatial distribution and aggregation trend of A-level scenic spots, then the minimum cumulative resistance model and PEST analysis method were used to find out the construction of ecotourism corridors and ecotourism areas respectively. On this basis, conclusions and suggestions were proposed for the construction of ecological corridors and ecotourism areas. The study's results indicate that: (1)The A-level scenic spots in the region have an "one main and one auxiliary" high concentration trend, as shown by the distribution of nuclear density results, and an "east-west" trend, according to the standard deviation ellipse results; (2)The eco-tourism corridor presents a "dual core" trend, with low ecological resistance values in the region northern foot of the Dabie Mountains in the south, and the plain and hilly area in the middle and east; (3)The follow-up research should extend to the middle and lower reaches of the Huaihe River Basin, and attempt to integrate the elements of the water area eco-tourism corridor and multi-source data organically.
