德州市优势土地利用类型与组合结构分析

Analysis on Dominant Land Use Types and Combination Structure in Dezhou

系统分析一个区域的优势土地利用类型与组合结构,是进一步优化区域土地资源配置的基础。本研究采用多样化指数、区位指数、组合系数法多角度定量测算了德州市的土地利用结构特征。结果显示:德州市土地利用类型多样化指数偏低,耕地类型占主导地位;在13个一级土地利用现状类型中,德城区7个一级地类具有区位优势,乐陵市、庆云县各2个一级地类具有区位优势,平原县、禹城市各1个一级地类具有区位优势;德州市属于耕地单一土地利用类型组合结构,德城区土地利用类型组合结构最为复杂,为耕地+林地+住宅用地+工矿用地+水域及水利设施用地+交通用地类型组合结构。

Systematic analysis of the dominant land use types and combination structure of a region,which is the basis for further optimizing the allocation of land resources.In this study,the diversification index,location index and combination coefficient method are used to quantitatively calculate the current land use type combination structure in Dezhou.The results show that the diversity index of land use types is low,and the cultivated land is dominant;Among the 13 primary land use types,7 primary land types in Decheng have location advantages,2 primary land types in Laoling and Qingyun have location advantages,1 primary land type in Pingyuan and Yucheng have location advantages;Dezhou belongs to the combination structure of single land use type of cultivated land,the combination structure of land use types in Decheng is the most complex,which is a combined structure of cultivated land+forest land+residential land+industrial and mining land+water area and water conservancy facilities land+transportation land.
