基于华北6省(市)2000、2005、2010年三期土地覆盖遥感数据,通过计算农田景观格局指数和农田景观转移矩阵,在省域范围的大空间尺度上分析了2000—2010年农田生态系统景观格局的变化特征。结果表明, 2000年至2010年华北6省(市)的农田景观格局变化主要表现为:耕地景观的面积在减少,破碎化程度在加大,斑块形状趋于简单化;园地景观的面积在增加,破碎化程度在降低,斑块形状趋于复杂化。耕地减少的面积主要转变为城镇,增加的面积主要来自水体;园地减少的面积主要转变为耕地,增加的面积主要来自耕地,园地景观主要与耕地景观相互转化。城镇化等人类活动加剧了耕地的减少和破碎化,应加强耕地保护,特别是耕...

Based on the remote sensing data of land cover in the year of 2000, 2005 and 2010, we calculated the pattern metrics and conversion matrix of cropland landscape, and analyzed the change characteristics of landscape pattern of farmland ecosystems from 2000 to 2010 on the large spatial scale in six provinces of North China. The results showed that the area of farmland was decreasing, the degree of farmland fragmentation was increasing, and the shape of farmland tended to be simplified from 2000 to 2010. The area of the orchard land was increasing, the degree of orchard land fragmentation was dec...
