摘要
为了研究昆明未来城区地域空间发展趋势,利用昆明主城区近10年3个不同时间段的现状影像资料,经纠正配准,提取建筑物及边界信息,通过叠加、比较、分析,发现昆明城区空间分布主要向外呈带状趋势拓展,通过对空间分布多种方法的比对,选择空间分布轴线的研究方法更能准确地描述昆明城区发展的规律和趋势。经过分析,预测昆明城区未来的拓展方向,将沿分布轴线的走向往外平移推进。
In order to study the future development trend of Kunming urban district space, use of Kunming main city of nearly 10 years in 3 different time periods of image data, the correct registration, building extraction and boundary information, through the stack, comparison, analysis, discover Kunming City spatial distribution of the main zonal trend to expand outward, the spatial distribution of multiple method comparison spatial distribution of axis, choice of research method can more accurately describe the developing law and trend of Kunming City. After the analysis, prediction of Kunming City development direction in the future, will be distributed along a axis to advance towards translation.
