土地利用構成比関数:ミクロな土地利用混合を把握する一手法 Land Use Ratio Function: a Tool to Analyze Land Use Mixture Closely
Access this Article
The aim of this study is to develop a method to analyze land use mixture closely based on geographical information systems (GIS). To this end, a function that indicates land use mixture closely ( land use ratio function ) is proposed. First, land use ratio function is formulated. It is defined at each point of a region as land use ratio vector of the area within a circular window with center at the point. Second, the implication of the function is discussed. The function can be viewed as the differential of land use ratio when marginal problems are considered, and as an estimate of the probability vector of a model to simulate urban land use transition. In this model, the land use of each parcel has a multinominal distribution, of which the probability vector can be estimated by land use ratio function of the parcel. Third, two methods to determine the appropriate radius of the circular window based on Akaike information criterion are proposed.
