| 中文摘要: |
| 随着城市化进程的加快,城市河湖水系格局发生了显著改变,并引起水系连通功能的相应变化。为了定量评估城市化进程对水系连通状况的影响程度,本文分别构建了两套指标体系用于描述城市水系连通形态和连通功能的变化情况,进而运用统计学方法分析了水系连通形态指标与连通功能指标之间的相关关系,在此基础之上建立相应的方程组来定量描述水系连通形态变化对连通功能的影响,最后以郑州市为例开展了实例研究,确定了满足郑州市未来城市发展功能定位的水系连通形态指标阈值区间。 |
| 英文摘要: |
| As the speeding up of urbanization, the form of interconnected river system network (IRSN) in city has changed greatly,which has brought the corresponding changes of the function of IRSN. In order to evaluate quantitatively the influence of the urbanization process on the status of IRSN,two set of index systems were developed to describe the form and function of IRSN. Then the statistical methods were applied to analyze the correlation of the form indexes and the function indexes of IRSN. Based on this, the corresponding equations were developed to describe the influence of the changes of the IRSN form indexes on the function indexes. Finally, taking Zhengzhou City as an example, the threshold intervals of the IRSN form indexes which can meet the demand of future development function of Zhengzhou City were determined. |
