【摘要】：改革开放以来中国城市化进程不断加快,越来越多的农村人口涌向城市,城市人口数目与日俱增,土地资源日显稀缺,城市的建设和发展面临巨大的挑战。利用传统方法测算建筑容积率比较复杂,需要进行实地测量,人力物力耗费大,数据更新周期长,在面积比较大的地区不适用,同时建筑高度的测量也不易实现,实际操作具有一定的局限性。随着遥感技术不断发展,高分辨率影像的出现为建筑容积率的估算开辟了一种新的方法和手段,填补了遥感技术在建筑容积率方面应用的空白。与传统测量方法相比,遥感手段具有测算时间短,覆盖范围大,可行性强等优势,能够节省大量的人力物力,并且也使遥感数据得到充分利用。本文以分辨率为0.61m的Quickbird遥感影像数据为基础,用不同的方法估算建筑类型不同的建筑容积率。对于多层及高层建筑物,提取建筑物阴影信息,结合实际调查数据,将建筑物阴影面积与调查的建筑物总面积进行回归分析,得到回归模型,依此计算出整个研究区的多层及高层建筑的建筑容积率;对于平房区,由于建筑物高度较低,很难提取阴影面积,因此无法通过阴影面积估算建筑容积率,而是根据实际调查数据,总结一般规律,应用到整个研究区的平房区。经验证使用上述方法估算城市建筑容积率简便快捷,同时精度较高。计算结果能够为城市总体规划及城市发展等提供决策支持服务,具有一定的理论价值。
[Abstract]:Since the reform and opening-up, China's urbanization process has been accelerating, more and more rural people are pouring into cities, the number of urban population is increasing, land resources are becoming scarce, and urban construction and development are facing enormous challenges. With the continuous development of remote sensing technology, the appearance of high-resolution images has opened up a new method and means for estimating the building volume ratio, which fills in the building volume ratio of remote sensing technology. Compared with traditional methods, remote sensing has the advantages of short calculation time, large coverage and strong feasibility. It can save a lot of manpower and material resources and make full use of remote sensing data. For multi-storey and high-rise buildings, the shadow information of buildings is extracted. Combined with the actual survey data, the shadow area of buildings and the total area of buildings investigated are regressed to get the regression model, and then the building volume ratio of multi-storey and high-rise buildings in the whole study area is calculated. Because of the low height of buildings, it is difficult to extract the shadow area. Therefore, it is impossible to estimate the building volume rate by the shadow area, but according to the actual survey data, the general rules are summarized and applied to the whole study area of the bungalow area. It is of theoretical value to provide decision support services such as physical planning and urban development.
