| 摘 要： | 借助地理信息系统技术,利用LUCC数据,分析了豫东平原1980-2000年农业景观格局动态变化特征及其驱动因素.结果表明,1980-2000年研究区居民点与建设用地从4 998.51 km2 增加到5 212.39 km2,种植业用地为基质的农业景观相对稳定,1980年占研究区土地总面积的80.07%,2000年占79.88%,其它类型用地面积均有不同程度的减少.国家土地利用政策和人口政策是该区土地利用变化的主要驱动因素.探索该区土地优化利用方式对实现农业可持续发展具有重要意义.

| Abstract: | Using geographic information system technology and relative LUCC data,the landscape pattern dynamics and its driving factors of the Eastern Henan Province Plain from 1980 to 2000 were analyzed.The results showed that the area of rural living and construction increased from 4 998.51 km2 to 5 212.39 km2 from 1980 to 2000.The agricultural landscape primarily for crop cultivation,was relatively stable.In 1980,cropland area was 80.07% of the total land area and 79.88% in 2000,while the area of other types of lan... |
