绿色建筑发展的时空格局演化及其空间关联性分析—基于2008-2015年中国绿色建筑的时间序列数据

Space-Tine Pattern Evolution and Spatial Correlation Analysis of Green Building in ChinaBased on Time Series Data from 2008-2015

摘要:

为了正确认识和评估我国绿色建筑发展态势,本文运用2008-2015年中国绿色建筑评价标识项目数量统计,基于标准差椭圆理论体系对我国绿色建筑时空格局演化进行了测度。研究发现：我国绿色建筑发展椭圆中心集中于安徽与河南交界地区、重心由东向西移动,椭圆范围主要涵盖京津冀、长三角、珠三角和沿海地区,椭圆形状呈现扩张和扁平化趋势,方向具有逆时针旋转发展趋势。在此基础上,运用空间自相关理论,研究绿色建筑发展的空间关联性,得出我国绿色建筑发展存在空间正相关,集聚现象突出,区域发展差异性较大。

Abstract:

Green building is an important measure of energy saving and emission reduction. To promote the development of green building, the first task is to recognize the present situation. This paper has studied the temporal and spatial pattern evolution of green buildings in China based on Standard deviation ellipse theory after statistical analysis of the number of green building evaluation and identification items from 2008 to 2015. The result shows that: 1) the ellipse centers of green building development were mainly located in Anhui and Henan; 2) the ellipse centers of green building development moved from the east to the west; 3) The scope of the ellipse mainly covered Beijing, Tianjin, the Yangtze River Delta, Pearl River Delta and coastal areas; 4) The ellipse shape presents the tendency of expansion and flattening, and the direction of the ellipse is counterclockwise. Then, this article has also studied spatial correlation of green building development by using Spatial Autocorrelation Theory. We can know from the results that there is a positive correlation in green building development. That can explains the agglomeration and unbalanced-development phenomenon is serious for green building.
