摘要
为提高肥力利用效率,保护农业生产环境,以1点/km2的精度,依据嘉善县土壤有效肥力实测数据,采用层次分析法和地统计学方法,建立了数学评价模型,对土壤有效肥力进行综合评价,将该县农田肥力划分了5个级别,评价结果显示嘉善农业土壤的有效肥力等级以良好级为主,占评价面积的55.56%。
To improve fertility use efficiency,protect the agricultural production environment in order to 1 point /km2 accuracy,according to Jiashan County in soil fertility and measured data,using hierarchical analysis and geostatistical methods,and establish a mathematical evaluation model,the effective fertility of the soil to conduct a comprehensive evaluation of the fertility of the county＇s farmland into a five-level,the evaluation results show that the effective fertility of agricultural soils Jiashan level with a good class-based,accounting for 55.56% area of evaluation.
