摘要
根据信息熵的基本原理,对2009—2013年贵州省试验区毕节市各区县的土地统计数据进行了土地利用动态变化的分析,并运用灰色预测模型GM(1,1)预测了2014—2023年毕节市土地利用结构的信息熵、均衡度和优势度三个指标。结果表明:2009—2013年期间毕节市土地利用变化为耕地、林地等土地利用类型不断减少,园地、交通运输、城镇村及工矿用地等土地利用类型不断增加;毕节市土地利用结构的信息熵和均衡度呈逐年递增趋势,优势度逐年递减,说明该市经济发展的同时,土地利用结构发展缓慢且均衡。
The land use dynamic change is analyzed by land statistical data in Guizhou pilot area Bijie city between 2009 and 2013 based on information entropy theory. Information entropy, balance degree and dominance of land use structure in Bijie city from 2014 to 2023 are predicted by using gray prediction model GM（ 1,1 ）. Results show that a decreasing number of lands were used as cultivated land and forest land, while an increasing number of lands were used as garden, transportation, urban village and industrial land from 2009 to 2013; Information entropy and balance degree of land use structure in Bijie city increase gradually annually, and dominance presents degenerative trend, which suggests that the land use structure develops slowly and evenly with the city＇ s economic development.
