The methods of combining the multiple parameters with other factors into one index have been studied, but due to the lack of criteria for precise evaluation, only general conclusions can be made. However, the large and significant correlation obtained from Combined GIS Method and Principal Component Analysis (PCA) indicate the compatibility between these two methods.
