【摘要】:以大连市中山区2003年、2013年城市三维建筑数据为基础,选取三维景观指标,运用Arc GIS空间分析方法从多个角度来研究城市10年间建筑景观格局时空分异特征。结果表明:1大连市中山区建筑加权平均高度和体积分别增加7.87 m、277.25×104m~3;地块覆盖率减少了16.27%,容积率增加了20.67%,反映出城市水平和垂直空间分别呈收缩、扩展的态势。2中山区城市天际线起伏差异明显,东—西方向呈逐渐增高的趋势,南—北方向呈"北部高峰,中部和南部平缓"格局。城市高层建筑主要集中于城市的西北部,且2013年建筑最高点中心裕景比2003年宏进大厦高140 m。3建筑覆盖率和容积率在空间分布上差异明显,低和极低覆盖率与容积率地块所占比例大,分别增加了8.3%、-4.33%;高和极高覆盖率与容积率地块所占比例少,且集中分布在青泥洼桥和人民路街道。4 2003年超高层建筑在空间分布上呈"聚集—离散"状态,即在距离660 m尺度范围内呈聚集状态,大于660 m时呈离散分布,其他三种建筑类型在空间上都呈一定的聚集分布状态;2013年4种不同类型建筑在空间分布上都呈现一定的聚集分布状态,聚集程度为:超高层建筑低层建筑多层建筑高层建筑。
[Abstract]:Based on the urban 3D building data of Zhongshan District of Dalian City in 2003 and 2013, the spatial and temporal differentiation characteristics of urban architectural landscape pattern in the past 10 years were studied by using Arc GIS spatial analysis method. The results show that: (1) the weighted average height and volume of buildings in Zhongshan District of Dalian City increase by 7.87 m and 277.25 脳 10 ~ 4 m 鈮,
