摘要: 随着我国城市化进程的加快,城市建设用地规模进一步增加,同时带来交通拥堵、环境污染、绿地减少、城市热岛等城市问题。本文综合利用2015年地理国情普查数据、2011和2013年遥感数据,通过建立城市扩张强度指数,运用统计分析、空间聚类等方法,确定了顺德区建设用地在过去4年间年均增长率为1.8%,其中新城区的年均增长率超过14%;此外还发现主城区的扩展模式主要为填充式扩展,其中大良街道和勒流街道主要为工业园区的扩展,伦教街道主要为中央公园的扩展,容桂街道主要为物流园的扩展。

关键词: 城市建设用地扩张, 时空演变, 地理国情, GIS分析

Abstract: With the acceleration of China's urbanization, the scale of urban construction land has been further increased, bringing about urban problems such as traffic congestion, environmental pollution, reduction of green space and urban heat island. In this paper, based on the comprehensive use of the 2015 national geographic census data, 2011 and 2013 remote sensing data, through the establishment of urban expansion intensity index, the use of statistical analysis, spatial clustering and other methods, it determines the rapid expansion of construction land in Shunde district in the past four years, the average annual growth rate of 1.8%, including the average annual growth rate of more than 14% in the new urban area. In addition, it is also finds that the expansion mode of the main urban area is mainly filled expansion, among which Daliang street and Leliu street are mainly the expansion of industrial park, Lunjiao street is mainly the expansion of central park, and Ronggui street is mainly the expansion of logistics park.

Key words: urban construction land expansion, time and space evolution, geographical conditions, GIS analysis
