基于计量地理模型和信息熵的湖北省土地利用结构地域差异研究

Study on the Regional Difference of Land Use Structure in Hubei Province Based on Quantitative Geography Model and Information Entropy

运用计量地理模型、信息熵的方法,分析湖北省17个市(州)土地利用结构的地域差异,研究土地利用信息熵和经济发展水平之间的关系。结果表明:各市州的土地利用多样化差异较大,多样化空间格局整体呈现东部偏高、中部均匀、西部较低的递进结构;耕地、城镇村及工矿用地、交通运输用地、水域及水利设施用地具有明显的区位意义,林地、草地、其他土地一般,园地不显著;土地利用信息熵的空间格局呈现高信息熵区域主要聚集在东部、中高信息熵区域位于中部、中低和低信息熵区域主要分布在西部的递进规律。土地利用信息熵与地区经济发展水平并无密切关系,与土地利用的多样化具有紧密关系。

The purpose of this study was to explore the land utilization structure in 17 cities of Hubei Province and the relationship between the entropy of land use and the level of economic development. The quantitative geog- raphy models and information entropy were employed. The results showed as follows ： （ 1 ） There were obvious differ- ences in the land use diversity among the cities, which showing a progressive structure like high diversity in east- ern, uniformly in central and lower in western; （2） Arable land, urban village and industrial land, transportation land, water and conservancy facilities land had obvious location significance, woodland, grassland and other land in general, garden not significant ; （3） There was a spatial distribution law for the information entropy of land use, which showed progressively decreased from the east to west. It is concluded that the entropy of land use and the lev- el of economic development is not closely related, but there is a close relationship between the entropy of land use and the land use diversity.
