From: Study on coupling degree of rail transit capacity and land use based on multivariate data from cloud platform

ClassificationCategoryIndicatorMeasurement
Land intensive use indicatorFloor area ratioL1Building area divided by land area
Building densityL2Building floor area divided by land area
Land use information entropyL3\( {H}_L=-\sum \limits_{i=1}^n{A}_i\mathit{\ln}{A}_i \)
Ai : The area of the i-type land area in the affected area as a percentage of the total land area in the area;
n: the number of land use types in the area
Proportion of land for public facilitiesL4Area of land for public facilities divided by land area
Proportion of land for commercial facilitiesL5Area of land for commercial facilities divided by land area
Proportion of land for residentL6Area of land for resident divided by land area
Density of facilities POIL7Total POI divided by land area
Facility POI information entropyL8\( {H}_P=-\sum \limits_{i=1}^n{P}_i\mathit{\ln}{P}_i \)
