摘  要:
以芜湖市土地利用结构作为研究对象,运用信息熵理论对区域土地利用结构的时间变化规律和空间分异特征进行研究,并对影响其信息熵变化的因素进行分析。结果表明:芜湖市土地利用结构信息熵时间上呈现增长的态势,土地利用结构均衡度均较高;空间分异上呈现市辖区熵值普遍高于下辖县,下辖县的农用地单一优势度较高导致熵值偏低;通过相关性分析,得出土地利用结构是影响熵值增长的直接因素,人口经济发展状况、城镇化水平以及产业结构与信息熵的上升有着十分密切的关系。

摘  要:
Taking the land use structure in Wuhu as the research object,the information entropy theory was applied to study the temporal variation and spatial differentiation characteristics of the regional land use structure,and the factors that affect the information entropy change were analyzed. The results showed that the information entropy of land use structure in Wuhu was increasing in time,and the balance of land use structure was high. The spatial differentiation was generally higher than the entropy of municipal districts,municipal county farmland single high degree of dominance leads to low entropy; It was concluded that the land use structure was the direct factor affecting the entropy growth through correlational analyses,there was a close relationship between the development of population economy,the level of urbanization,the industrial structure and the rise of the entropy of information.
