2011-2016年鞍山市土地利用及景观格局演变特征
|
摘要
本文选取2011年和2016年鞍山市遥感影像,结合实地核查,在地理信息系统技术的支持下,利用转移矩阵模型和景观格局指数分析鞍山市的土地利用及景观格局变化特征。结果表明:鞍山市土地利用变化主要表现为耕地和林地面积减少,草地、水域、城乡工矿居民用地和未利用土地面积增加。城乡工矿居民用地面积增长速度最快,面积增加主要来自耕地和林地。鞍山市景观破碎度增加,边界形状复杂度、离散度增加。耕地、草地破碎度增加;林地、水域破碎度降低;未利用土地基本稳定。城乡工矿居民用地斑块数量增加,边界密度增加,鞍山市城镇化进程加快。
This paper selects the remote sensing images of Anshan City in 2011 and 2016,combined with on-site verification,and with the support of GIS technology,using the transfer matrix model and landscape pattern index to analyze the land use and landscape pattern changes in Anshan City.The results show that the land use change in Anshan City is mainly reflected in the reduction of cultivated land and forest land area,and the increase of grassland,water area,urban and rural industrial and mining residential land and unused land area. The area of urban and rural industrial and mining residents has the fastest growth rate,and the increase in area mainly comes from cultivated land and forest land. The landscape fragmentation degree of Anshan City increased,and the boundary shape complexity and dispersion increased. The degree of fragmentation of cultivated land and grassland increased; the fragmentation degree of forest land and water area decreased; the unused land was basically stable. The number of plaques in urban and rural industrial and mining residents has increased,the boundary density has increased,and the urbanization process in Anshan City has accelerated.
