岳阳市土地利用结构变化与土地利用绩效的关联度分析

利用信息熵、灰色关联等分析方法对岳阳市2009—2015年土地利用结构信息熵变化规律、土地利用绩效指数以及它们之间的内在联系进行系统分析。结果表明:1时间上,岳阳市土地利用结构信息熵持续增长,土地利用变化主要表现为城镇村及工矿用地、交通运输用地、耕地的大幅增加以及园地、林地、水域及水利设施用地等地类的减少;2空间上,岳阳市各地区信息熵存在较大差异,中心城区信息熵明显高于其他区域,且经济发展水平与信息熵值呈正相关;3岳阳市土地利用绩效指数逐年上升,其中经济绩效对综合绩效的带动作用最明显,公平绩效则相对滞后;4与土地利用绩效相关性最显著的是城镇村及工矿用地、交通运输用地,但关联系数都较低。

Evolution of Land Use Structure and Its Correlation Degree with Land Use Performance in Yueyang City

The paper systematically studied the spatial-temporal evolution of information entropy of land-use structure of Yueyang City,the performance index of land use,and the inner link between them under the application of information entropy and grey correlation analysis. In terms of time,information entropy of land use in Yueyang City continues to rise,and land for cities and villages,industry and mining,transportation and plantation increases signif-icantly,while land for garden,forest,water conservancy facilities and water area declines. In terms of space,there are large differences of information entropy between different districts of Yueyang,the information entropy of central city is much higher than that of other districts,and level of economic development is proportionate to information en-tropy. Performance index of land use rises steadily and the economic performance has played vital role to comprehen-sive performance. However,justice performance has fallen behind the others. The land for cities and villages,mining and industry,transportation has the most crucial effect on land use performance,but the correlation degree is low.
