Land use mix

Description

The Shannon Entropy Index: A measure of how mixed land uses most relevant for PA are in a neighbourhood (Range: 0 to 1; 1= most mixed; 0=least mixed) LUM=(-1) Sk(pklnpk)/ln N p is the proportion of land area devoted to the specific land use (k) in each buffer divided by ln N N is the number of land uses under consideration. In this case N=5 (i.e. residential; commercial; institutional/governmental; recreational and mixed areas) The proportions (pk) were calculated as the land area devoted to a specific land use divided by the total area of walkable land uses in each buffer. Note: LUM=0 (i.e.; no mix) if none or only one of the relevant land uses fell into the buffer.
