| 摘 要： | 基于国家资源环境数据库土地利用数据,估算了1990年和2000年我国31个大城市的分形维,讨论了基于面积周长关系定义的分形维和基于周长尺度关系定义的分形维之间关系,表明二者之间虽有差异,但存在显著的线性正相关关系,即随着基于周长尺度关系定义的分形维数值增加,基于面积周长关系定义的分形维数值也增加.我国城市的分形维总体变化趋势是:从1990到2000年均呈减少趋势,且南方城市的分形维大于北方城市.造成这一现象的原因是区域自然地理环境和土地利用方式的差异.

| Abstract: | Using the National Resources and Environmental Database established by the IGSRR, CAS, we compute and analyze the fractal dimensions of 31 cities in China in 1990 and 2000, we also discuss the relationship between the fractal dimension respectively defined by area-perimeter and perimeter-ruler. It is found out that although there are some differences, the linear relationship between them is very remarkable. That is to say, when the fractal dimensions defined by perimeter-ruler increases, the fractal dimensions defined by areaperimeter also increases. In general, the trend of changes is that the fractal dimensions of most Chinese cities are reducing from the year 1990 to the year 2000, and the fractal dimensions of the southern cities are higher than those of the northern cities in China. We then analyze and conclude that these differences are caused by the differences of regional physical geography and land-use type. |
