“Guangdong Province has constructed a suitability evaluation system for small-scale cultivated land below 1/3 hm2 from four dimensions: basic conditions, natural quality, distribution and utilization, and cultivation conditions. The comprehensive evaluation shows that small-scale cultivated land in the province is highly concentrated in Meizhou, Heyuan, Zhanjiang and other areas, with the proportion of suitability grades 1-3 being 18%, 48%, and 34%, respectively. Based on this, it is divided into five categories of areas, including priority remediation areas, providing scientific basis for differentiated cultivated land remediation strategies.”
