| 摘 要： | 以青海高原东部农业区为研究区域,以1996-2005年土地利用现状调查与变更调查统计数据及统计年鉴提供的各类社会经济数据为依据,采用定性与定量相结合的方法,分析耕地变化过程与特点,探寻耕地变化驱动机制。研究结果表明,1996-2005年海东地区耕地面积总体呈下降趋势;耕地变化的主要驱动因素包括社会经济发展、政策调控驱动力两方面。其中,社会经济发展驱动力因子主要有人口、GDP、固定资产投资。政策调控驱动力因子主要有农业结构调整和生态退耕因素。

| Abstract: | Along with the economic developmemt and ecological environment constraction of western China,arable land was reduced in recent years.Taking agricultural areas in eastern Qinghai Plateau as study area,we discussed the arable land changes and driving force.The results indicated that arable land was reduced from 1996 to 2005.The population,GDP and fixed assets investment were the driving factors of socio-ecnomic development.The adjustment of agricultural strcture and ecological restoration were the driving factors of policy control. |
