中文摘要：

基于2000、2005、2012年的土地利用数据和景观格局指数,对河南省7种主要土地利用类型的演变情况和景观空间格局变化进行分析,探索河南省近期的景观空间格局演变规律及其成因。结果表明,2000-2005年、2005-2012年在河南省土地利用各类型中耕地（旱地和水田）面积始终最大,未利用土地面积始终最小;耕地（水田和旱地）、草地和林地面积总体呈减少趋势,水域、建设用地、未利用土地面积总体呈增加趋势,其中耕地中的旱地面积减少最多,建设用地面积增加最多;景观水平指数中斑块数量、斑块密度、平均分维数、Shannon多样性指数和Shannon均匀度指数呈增大趋势,而平均斑块面积呈减少趋势,土地破碎化加剧,斑块形状变得不规则,景观空间连接性下降,景观要素空间分布不均衡。总体而言,河南省土地受城市化发展影响较大,在以后的经济战略制定时要注意把握人与自然的协调,做好城市化对耕地影响的度量。

英文摘要：

Based on land use data and landscape pattern indexes in 2000,2005 and 2012,this paper analyzed the variation of landscape pattern,and explored both evolution trend and causes of recent landscape pattern in Henan province.The results showed that cultivated land（dry land and paddy field）was the dominant landscape type,and unused land area was the smallest from 2000 to 2005and from 2005 to 2012;on the whole cultivated land（dry land and paddy field）,meadows and woodland landscape area decreased,water area,construction land and unused land area increased,the greatest decrease in area was dry land,and the greatest increase in area was construction land;patch amount,patch density,mean fractal dimensions,Shannon diversity index and Shannon evenness index increased,the average patch area decreased,land fragmentation exacerbated,patch shape became irregular,the connectivity of landscape space decreased,and the spatial distribution of landscape elements was uneven.On the whole,the land of Henan province was influenced greatly by the urbanization development,and the coordination of human and nature should be noticed.
