考虑水功能需求的海口市水系连通指标阈值研究
|
摘要
随着城市的快速发展,我国河湖水系结构逐渐向单一化趋势发展,由此产生了一系列的环境问题。以海口市为研究区域,建立了城市化对水系连通性影响的定量分析指标体系,通过ENVI、Arc GIS软件以及资料收集,得到2000-2016年海口市水系连通形态和功能指标,运用统计学方法分析了水系连通功能指标和水系连通形态指标关系,并结合海口市水系的未来水功能,确定了水系连通指标阈值。结果表明:节点连接率的阀值为[1. 0152,1. 2471];水系环度的阀值为[0. 0049,0. 0111];河网密度的阀值为[0. 0585,0. 1786];水系连通度的阀值为[0. 3384,0. 3541],阈值的确定可为城市化对水系连通影响地区的水资源规划管理,以及城市建设等提供参考。
With the rapid development of the cities,the structure of rivers and lakes in China has gradually evolved toward a singular trend,which has created a series of environmental problems. This paper takes Haikou City as the research area to establish a quantitative analysis index system for the influence of urbanization on water system connectivity. Through ENVI,ArcGIS software and data collection,the data of connectivity patterns and functional indicators of Haikou City from 2000 to 2016 are obtained. The statistical analysis were used to study the relationship between the water system connectivity function index and the water system connectivity morphological index,and to determine the water system connectivity index threshold by combining with the future water function of the Haikou city water system. The results showed that the index threshold is the node connection rate: [1. 0152,1. 2471]; the water system ring degree: [0. 0049,0. 0111]; the river network density: [0. 0585,0. 1786]; the water system connectivity: [0. 3384,0. 3541]. The determination of threshold can provide reference for urbanization of water resources planning and management in areas affected by water system,as well as urban construction.
