摘要
对土地利用竞争模式进行了论述,根据上黄试区22年统计数据,分析了人口增长及其土地利用变化。结果表明:政策因素是环境响应的主体,并在控制土地利用的方向上起积极作用;技术因素可以缓解土地利用的竞争压力,深刻影响土地变化,改变土地利用的竞争格局;传统特色农业及以技术进步为基础的特色农业是现在及未来黄土丘陵区土地利用的发展方向。
This paper states the competitive model of land-use, analyzing the population increase and the change of land-use according to statistic data of Shandhuang experimental area from 1982 to 2004. The result showed that the policy factor is the principal part of responding to environment, and has positive action to control the land-use. Technology factor can abate the competitive press of landuse, the progress of technique can deeply influence the change of land-use, and change the competitive mode of land-use. Traditional characteristic agriculture and special agriculture based on the technique progresses are the developmental direction of Loess Hilly-gully region.
