基于农业地质的福建光泽耕地质量评价及其利用建议

Cultivated Land Quality Evaluation and Utilization Suggestions Based on Agricultural Geology in Guangze County,Fujian Province

以福建光泽的耕地为研究对象,基于农业地质角度以及从土壤质量内涵出发,将农业地质调查成果中的土壤地球化学元素与土壤肥力作为评价指标,结合土地变更调查成果等相关数据,建立耕地质量综合评价的指标体系,将耕地土壤肥力、耕地利用条件以及土壤微量元素进行综合分析,探讨研究区基于农业地质的耕地质量评价指标体系及方法。结合对光泽耕地的实证分析,探讨不同耕地质量以及有益微量元素含量耕地适合的利用方向,进行合理的耕地利用分区应用研究,为该研究区域发展特色农业、耕地保护和利用提供借鉴意义。

In this paper,Guangze County,Fujian Province is taken as the study area.Based on agricultural geology,starting from the connotation of soil quality,the soil environmental quality,soil geochemical elements and soil fertility in agricultural geological survey results are taken as evaluation indexes.Based on the relevant data of agricultural geological survey and land change survey results,an index system for comprehensive evaluation of cultivated land quality is established.The cultivated land soil fertility,cultivated land utilization conditions and soil trace elements are comprehensively analyzed,and the evaluation index system and method of cultivated land quality based on agricultural geology in the study area are discussed.Combined with the empirical analysis of Guangze County,the suitable utilization direction of cultivated land with different cultivated land quality,soil environmental quality and beneficial trace element content was discussed,and the rational application of cultivated land utilization zoning was studied,which provided reference for the development of characteristic agriculture and the protection and utilization of cultivated land in the study area.
