摘　　要：文章以许昌市2010和2015年的土地利用遥感数据为依据,在Arc GIS和Fragstats软件的技术支持下,运用土地利用转移矩阵和景观指数法,研究许昌市土地覆被和景观格局演变情况。结果表明:2010-2015年期间,许昌市的林地和耕地范围逐渐缩小,水域、建设用地和草地范围连续扩大,其中建设用地面积增幅最大,为10.98%,增加比例也最大。由于人类社会活动对许昌市景观空间格局的影响,使得区域严重分散,景观结构更加繁杂,斑块形状更加无序,景观异质性程度明显增加。Based on Xuchang City’s research area and Xuchang City’s land use remote sensing data during years 2010 and 2015,this paper studies the land cover and landscape pattern evolution of Xuchang City,with the technical support of Arc GIS software and Fragstats software.The study shows that between 2010-2015,the area of forest land and cultivated land in Xuchang City gradually decreased,while the area of water,construction land and grassland continued to expand,with the area of construction land increasing by 10.98 percent,the largest increase.Because of the influence of human social activities on the landscape spatial pattern of Xuchang City,the area is seriously dispersed,the landscape structure is more complicated,the shape of the plaqueis is more disorderly,and the degree of landscape heterogeneity is obviously increased.
