基于景观生态学的南宁市区农村居民点变化研究

On Change of the Rural Residency in Nanning Urban Limits Based on Landscape Ecology

以南宁市区2003年、2008年和2013年3期土地利用变更调查为数据源,运用景观生态学方法对南宁市区2003—2013年农村居民点的用地面积、规模、形状及分布的动态变化过程进行研究。结果表明:景观生态学方法能较好地反映出近10年来南宁市区农村居民点用地布局的变化规律,对南宁市区农村居民点规划管理调控与空间布局优化具有一定的理论指导。2003—2013年南宁市区农村居民点用地面积不断增加,斑块平均规模不断下降,斑块形状不断向破碎、复杂和不规则转变,空间分布日益分散。

Based on land use change survey as a data source in the years 2003, 2008 and 2013, and on the use of landscape ecology method to study the rural residency in size, shape and distribution of the dynamic change process of Nanning from the year 2003 to 2013. The results showed that the landscape ecology method can better reflect the change of land use layout of rural residency in Nanning urban limits in the past 10 years,which can be some theoretical guidance to Nanning urban rural residency planning, management, regulation and space layout optimization. The area of rural residency in Nanning urban limits has been increasing, the average size of the patch has been declining, the shape of the patch has been broken, complex and irregular changing, and the spatial distribution has become more and more dispersed.
