基于电子地图兴趣点的城乡边缘带识别方法——以银川市为例

Identification Method of Rural-Urban Fringe Based on POI of Electronic Map——Taking Yinchuan City as an Example

城乡边缘带是城市与乡村用地的结合地带,是城市核心城区的蔓延地带。当今城市的发展面临着交通堵塞、住房不足、环境污染和疾病等方面的问题,及时获取城乡边缘带的实际范围,对引导和调控城市的可持续发展具有重要意义。论文利用POI数据,结合2016年银川市影像数据,通过核密度分析法,对银川市2016年的城乡边缘带进行空间识别。

The urban and rural fringe is the combination zone of urban and rural land, and it is the sprawling zone of the core urban area of the city. Today＇s urban development is faced with problems such as traffc congestion, inadequate housing, environmental pollution and diseases. It is important to obtain the actual scope of urban and rural fringe areas in a timely manner, and it is of great signifcance for guiding and controlling the sustainable development of cities. The paper uses POI data, combines with the image data of Yinchuan city in 2016, and uses the nuclear density analysis method to carry out spatial recognition of the urban and rural fringe in Yinchuan city in 2016.
