广州市耕地非粮化空间格局研究
Research on Spatial Pattern of Non-grain Cultivated Land in Guangzhou City
摘要
Abstract
In order to understand the trend of non-grain cultivated land in Guangzhou City and reduce the threat of non-grain cultivated land,taking towns and streets as the basic evaluation unit,we calculated their non-grain cultivated land rate,and used spatial autocorrelation analysis method to explore the spatial distribution rules of non-grain cultivated land.The results showed that in 2019,the area of non-grain cultivated land in Guangzhou City was 434.51 km2,with a non-grain cultivated land rate of 65.7%.The phenomenon of non-grain cultivated land was widespread.The spatial distribution of non-grain cultivated land showed a high concentration near the urban center and low concentration in the peripheral areas.The non-grain cultivated land area is mainly concentrated in the south of Panyu District,the north of Nansha District,the north of Baiyun District,and the south of Zengcheng District.The spatial distribution of non-grain cultivated land rate showed a central high,followed by low and high in the south,and high and low in the north.The high non-grain cultivated land rate was mainly concentrated in the south of Panyu District,Nansha District,Huangpu District,Baiyun District,and other areas.关键词
