以广西平果铝土矿区为研究对象,分析矿区的土地利用结构现状及存在的主要问题,提出土地利用结构调整方案;在此基础上构建了耕地总量动态平衡综合指数,并对矿区的耕地总量情况进行了定量评价。结果表明:矿区的耕地总量已从1995、2002年的极不平衡状态提高到了2008的不平衡状态。随后分析了影响矿区耕地总量变化的因素及矿区实现耕地总量动态平衡的可行性与潜力,最后提出了实现矿区耕地总量动态平衡的对策。土地利用结构调整方案及耕地总量动态平衡的定量评价结果可为地方政府制定耕地总量动态平衡实施措施提供科学依据,并有利于平果铝矿区土地资源的可持续开发与利用。表6,参22。
Analyzed the present land use structure and existing problems in bauxite region in Pingguo county,proposed adjustment programs,and evaluated the status of total arable land using Dynamic Equilibrium Composite Index.The result showed the total cultivated land changed from bad disequilibrium from 1995-2002 to disequilibrium in 2008.Then the paper analyzed factors which affect total cultivated land in bauxite region and feasibility and potential of dynamic equilibrium of the total arable land,and at last the author put forward countermeasures.Adjustment programs of land use structure and the result of evaluation on dynamic equilibrium of the total arable land in the paper will provide a scientific basis on implement messures formulated by local government,and it will be beneficial to the sustainable development and utilization of land resources in bauxite region in Pingguo County.
