多源数据下广州都市农业时空特征解析与思考

Spatial & Temporal Characteristics Analysis of Urban Agriculture in Guangzhou Based on Multi-source Data

结合广州都市农业发展历程及土地利用前后10年变化,引入POI大数据剖析都市农业时空分布特征,同时选择广州典型区域(番禺区)开展实证研究。研究表明:2000年前后广州处于城市建设快速扩张阶段,不少农林用地被挤占,近郊呈现城乡界限模糊、用地混杂特征,农林用地是番禺区2007―2017年变化最大的类型之一;采摘垂钓类和休闲综合类是受城市扩张影响最大的两种类型,需重视未来发展保护与转型引导。针对存在的问题提出精细化划分农林用地、开展自适应研究、加大都市农业项目的扶持力度等建议。

Considering the development of urban agriculture in Guangzhou and the ten-year changes in land use,POI data was introduced to analyze the temporal and spatial distribution characteristics of urban agriculture.At the same time,Guangzhou Panyu District was taken as the empirical research object.The research results show that Guangzhou was in the rapid expansion stage of urban construction around 2000,and many agricultural and forestry land were occupied.The suburban areas showed the characteristics of blurred urban and rural boundaries and mixed land use.Agricultural and forestry land was one of the most changing land types in Panyu District from 2007 to 2017;Picking and fishing and leisure comprehensive types were the two types that were most affected by urban expansion,and attention should be paid to their future development,protection and transformation guidance.In view of the existing problems,the thoughts on finely dividing agricultural and forestry land,carrying out adaptive research,and increasing the support of urban agricultural projects,were put forward.
