中文摘要:
      【目的】为合理利用不同耕地质量的土地,提高耕地的保护与管理,促进农业产业结构调整和农 业可持续发展,掌握耕地质量的空间分布以及土壤养分状况。【方法】以广东省粮食生产功能区为研究区域, 利用 GIS 技术结合统计分析方法分析了粮食生产功能区的耕地地力等级和土壤养分的基本状况和空间分布格局。 【结果】广东省粮食生产功能区的耕地地力等级以三等、四等和二等为主,土壤有机质以三级(54.87%)、二 级(24.20%)和四级(17.03%)为主,土壤有效磷以二级(39.49%)、一级(31.16%)和三级(24.49%)为主, 土壤速效钾以四级(42.21%)、五级(23.47%)和三级(14.99%)为主。【结论】一等地力等级耕地面积少且 分布不均,二等地力等级耕地大面积分布在山区地区,三等和四等地力等级耕地空间分布较为均匀、遍布整个 粮食生产功能区,五等地主要分布在山区,粤东、粤西和珠三角的肇庆,六等地在珠三角肇庆、广州、东翼揭阳、 山区河源等地分布较多;土壤养分等级以三四级为主,不同养分之间存在差异。
英文摘要:
      【Objective】In order to rationally use land of different cultivated land qualities, improve the protection and management of cultivated land and promote the adjustment of agricultural industrial structure and sustainable agricultural development, it is particularly critical to grasp the spatial distribution of cultivated land quality and soil nutrient status.【Method】Taking the food production functional area in Guangdong Province as research area, and the GIS technology, combined with statistical analysis method, is used to analyze soil fertility level, soil nutrient status and spatial pattern of cultivated land in the food production functional areas.【Result】The cultivated land fertility of the food production functional areas in Guangdong Province is mainly classified as third-class, fourth-class and second-class; soil organic matter is classified as third-class(54.87%), second-class(24.20%) and fourth-class(17.03%); soil available phosphorus is mainly classified as Grade two(39.49%), Grade one(31.16%) and Grade three(24.49%); soil available potassium is mainly classified as Grade four(42.21%), Grade five(23.47%) and Grade three(14.99%).【Conclusion】The area of cultivated land with the first-class fertility is small and distributed unevenly; the cultivated land with the second-class fertility is widely distributed in mountain areas; the cultivated land with the third and fourth-class fertility is distributed more evenly in space, covering the entire food production functional areas; the fifth-class lands are mainly distributed in mountain area, including eastern Guangdong, western Guangdong and Zhaoqing in the Pearl River Delta. Sixth-class lands are mostly distributed in Zhaoqing, Guangzhou, east wing of Jieyang, mountainous area of Heyuan and other places in the Pearl River Delta. Soil nutrient levels are mainly Grade three and Grade four,and there are differences between different nutrients
