摘要: 珠三角地区的经济发展和城市化的快速推进带动着周边城市的发展。本文针对距离珠三角最近的山区县广宁县,利用2011—2017年的高分遥感影像土地调查监测数据,通过城市扩张的若干指标反映广宁县的城市扩张程度与此期间新增城市用地的来源,并通过计算景观指数分析广宁县县域内各种土地地类的景观分布,探究广宁县城市化扩张对土地的需求变化,找出山区县城市化用地的优化方案。

Abstract: The rapid economic development and urbanization in the Pearl River delta region drive the development of surrounding cities.This paper uses the land survey data which were obtained by high resolution remote sensing images from 2011 to 2017 to analyze urbanization of Guangning county,the nearest mountain county to the Pearl River delta.It reflects the urban expansion degree through calculating several indicators and finds out the source of the new urban land in each year.Meanwhile,the landscape distribution of the various types in the county district of Guangning county is analyzed by calculation of the landscape index.Finally,we explore the changing demand of land during the period of urbanization and seek out the optimizations of urbanized land in mountain county.

Key words: remote sensing, land monitoring data, urbanization, urban expansion
