以2009、2013和2015年三期日照市Landsat TM影像为数据基础,基于GIS空间分析方法和景观格局指数法对研究区的建设用地利用和景观格局变化情况进行分析。结果表明:2009~2015年,日照市城市建设用地规模呈扩张趋势,新增建设用地类型以工业用地为主,建设用地利用较为粗放;城市道路交通设施用地的扩展合理有序,居住用地空间分布较不均衡,人均绿地面积呈减少趋势;景观生态格局有向破碎化方向发展的趋势,景观多样性水平总体呈现上升趋势,农林用地面积基数大,生态型景观辐射范围和控制能力较强,非建设用地保障能力高,城市建设用地景观空间呈现聚集特征。
Based on the data of Landsat TM images of Rizhao City in 2009, 2013 and 2015, and based on GIS spatial analysis method and landscape pattern index method, the land use of construction land and the change of landscape pattern were analyzed. The results show that from 2009 to 2015, the scale of urban construction land in Rizhao is expanding. The types of newly-added land for construction are mainly industrial land and the land for construction is more extensive. The expansion of land for urban road transport facilities is reasonable and orderly, and the spatial distribution of residential land The area of landscape ecological diversity tends to be fragmented. The landscape diversity generally shows an upward trend. The area of land for agriculture and forestry is large, and the radiation range and control ability of ecological landscape are strong. The construction land has high guarantee ability and the landscape space of urban construction land presents the gathering features.
