摘要:

以1∶10 000土地利用现状图为空间数据框架基础,结合农业部门现有的土壤普查和样点调查分析资料进行耕地地力评价,相比目前我国测土配方施肥工作方案中以1∶50 000为基础进行的耕地地力评价结果,本研究方法的评价结果耕地分布的空间定位更正确、更切合现状,评价单元的划分更合理、耕地地力等级划分更加精细,能大幅度提高耕地地力评价的精度。本研究方法在耕地地力评价上的应用,有利于为建立测土配方施肥信息管理系统提供详细的基础信息和科学管理耕地,更好地满足精准农业和农业生产中施肥管理对耕地信息的需要。

Abstract:

The purpose of this paper was to evaluate cultivated land fertility based on land use status map at 1∶10 000 scale combined with existing soil survey and soil sample analysis data. The evaluation results showed that spatial positioning of cultivated land distribution was a more accurate and practical situation and that the assessment unit division of cultivated land classification was more reasonable and more sophisticated, and the evaluation accuracy was greatly improved, compared to evaluation at 1∶50 000 scale implemented in the work program of testing soil for formulated fertilization in our country. The research method in this paper was beneficial for the establishment of soil testing and formulated fertilization information management systems to provide detailed basic information and scientific management of farmland. It can better meet farmland information needs on precision agriculture and fertilizer management for agricultural production.


Key words: land use investigation, cultivated land fertility, fertility evaluation, testing soil for formulated fertilization
