Modelling the spatial variation of human population density using Taylor’s power law, Italy, 1971–2011
研究将泰勒幂律应用于意大利1971-2011年区域和省级人口密度,发现该定律适用于人口分布,且其斜率可作为人口空间分布均匀性的指标。
Taylor’s power law (Tpl) is applied to the human population density of Italian regions and provinces for the period 1971–2011. Three different weighting systems are used to estimate Tpl at the national and subnational levels in which seemingly unrelated regression models are adopted. The following results were found: Tpl is suitable for human populations and sensitive to the adopted weighting system; Tpl’s slope is positive and, at a subnational level, has an inverse behaviour with respect to the spatial variability of the weighting variables; and Tpl’s slope can be viewed as an indicator of a population’s spatial distribution homogeneity.
