青岛市土地利用转型研究分析

The response research of Land use transition in Qingdao

以1980年、1990年、2000年和2010年四期土地利用数据和社会经济统计数据为基础,借鉴地理信息技术,对青岛市土地利用转型进行测试和分析。研究表明,青岛市土地利用转型变化明显,主要表现为虽然建设用地占用大量耕地,但是,草地、林地和未利用地大量补充为耕地,使耕地面积在研究时段内略有增加;从影响因素来看,自然地理条件起决定作用,人口增加和经济发展具有强大的推动力,交通条件对土地利用转型表现出廊道效应,而区域规划项目的建设则具有很强的引导作用。同时,土地利用转型也产生了明显的效应,促进了青岛市的经济发展,改变了青岛市的产业结构,为青岛市人民提供了更多的就业机会,也给青岛市带来环境问题,影响人们的生活,亟待解决。最后,提出青岛市土地利用转型的政策建议。
