Design of spatial sampling in setting monitoring sites of residential land price

摘要

Neither Random nor stratified sampling can reflect the Dependence among land-price monitoring. Hence, based on Semi-variogram and analysising the anisotropy of different sites of land-price, some useful references are provided. Systematic unaligned sampling with a grid cell size of 1000x500 m was chosen on the basis of semi-variogram analysis, and the length of side is equal to 1/2 of range. At last, part region of the Changzhou city is selected as a study area to examine this method.
