Heterogeneous Fractal Characteristics of Landforms in the Water of the Xisha Islands Based on Multiple Linear Regression

Authors:Wang Xuli


In view of the obvious anisotropy of landforms in the water of the Xisha Islands based on multiple linear expression, the heterogeneous fractal characteristics of Geography in the water of the Xisha Islands are studied. In this method, multiple linear regression analysis method is used to extract the projection of the heterogeneous characteristics factors to obtain the heterogeneous characteristics of geometry in the water of the Xisha Islands. On the second basis, the irregularity of heterogeneous body in the water of the Xisha Islands is measured by the research method of geomorphic fractal characteristics based on projection coverage method. The results show that this method can effectively analyze the heterogeneous fractal characteristics of geometry in the water of the Xisha Islands. The fractal dimension values of different types of landforms in Xisha Islands in the corresponding region are as follows: water area in the high mountain area > water area in the middle and low mountain area > water area in the basin area, which reflects the difference of surface roughness or complexity of different types of landforms. The calculated fractal dimension value is helpful to reveal the heterogeneity of the general geomorphic characteristics in different development stages.
