Analysis of Spatial Distribution Pattern of Main Tourism Resources in Hainan Island Based on GIS

This chapter takes Hainan main tourism resources as research object, GIS as platform, and the nearest neighbor index (R), geographic concentration index (G), Gini coefficient (Gini), Equilibrium ratio (ER) as calculation model to quantitatively analyze spatial distribution characteristics of main tourism resources in Hainan Island. The result shows that the nearest neighbor index R = 0.728, illustrating main tourism resources in Hainan Island are of clustered distribution; geographic concentration index G = 27.322, illustrating main tourism resources in Hainan Island are spatially concentrated; gene coefficient Gini = 0.945 m, illustrating main tourism resources are of unbalanced distribution between administrative regions. Economic equilibrium ratio coefficient ER = 16.13, area balance ratio coefficient ER = 13.041, suggesting that economy and area play little influence on the distribution of main tourism resources in Hainan Island. To better compare the differences between all the cities and counties, the equilibrium ratio coefficient is decomposed, the result shows that the maximum value of area balance ratio coefficient is in Wushizhang, the minimum value is in Haikou, the maximum value of economic equilibrium ratio is in Sanya, the minimum value is in Ledong.
