黄河三角洲高效生态经济区土地利用分析

Analysis of Land Use Actuality in Yellow River Delta High-Efficiency Economic Zone

利用区位熵、均匀度和优势度基本原理对黄河三角洲高效生态经济区各种土地利用类型和利用空间结构进行定量化研究,并结合土地利用率、垦殖率、森林覆盖率三个指标对土地利用程度进行了分析,从土地利用经济效益、社会效益、生态效益三方面对土地利用效益进行了评价.在分析土地利用现状的基础上,找出土地利用中存在的问题,并提出了合理利用土地的建议.

Location quotient, uniformity and dominance degree theory were used to study the different type of land use as well as quantification of the land use spatial structure in Yellow River Delta High-Efficiency Eco- nomic Zone. A comprehensive evaluation of land use efficiency was analyzed by using land utilization rate, reclamation ratio and forest coverage rate as the analysis indicators of land use degree according to economic benefit, social benefit and ecological benefit of land use. Based on the present land use status, the existing problems in land use were found out. Furthermore, some reasonable suggestions of land use were put forward.
