摘要
基于1994年和2005年TM影像,在遥感和地理信息系统技术支持下,分析武汉市城区土地利用及景观格局变化特征,利用CA_Markov模型预测研究区2016年土地利用景观格局。结果表明:研究期内耕地、草地和水域大面积减少,建设用地和林地则以较快速度增加,未利用地有所减少。景观格局变化呈现出"破碎度增加、多样性和均匀度微减、优势度微增"的特征。预计到2016年,耕地和水域将继续大面积减少,建设用地仍将以较大幅度扩展,林地增加速度趋缓。
Applying remote sensing and GIS tools, this paper uses two Landsat TM images acquired respectively in 1994 and 2005 to analyze changes of land use and landscape pattern in Wuhan City, and then integrates the Markov process with cellular automata （CA） model to simulate the scenarios of land use in 2016. The results show that the predominant land use types were cultivated land, water-body, and land for construction. From 1994 to 2005, the investigated area experienced notable increment of land for construction and forest land and a great loss of cultivated land, grassland,and water-body, that most of the reduced cultivated land was used for construction, and that the reduced water-body, grassland and forest land were mainly converted into cultivated land. During the same period, the indices of landscape fragmentation and dominance increased while the indices of diversity and evenness slightly decreased. By 2016, cultivated land and water-body would be reduced greatly while land for construction and forest land would still increase.
