摘要
为及时准确掌握山丹县等级耕地地理质量、土壤地力肥力资源状况等,合理充分利用山丹县域等级耕地土壤资源,通过分析研究山丹县的农田品质级别分类以及农田土质肥力现状,进而及时了解山丹县农田地力现状并为其发展提供科学依据,同时为山丹县农田进行质量改善提供对策,在根据《耕地质量等级》国家标准(GB/T33469-2016)的相关要求基础上,充分利用GIS技术,运用空间结构分析、层次结构分析、综合指数等方法对山丹县耕地质量进行综合评价。其农田评价检测成果,比较准确地反应了山丹县农田的品质等级状况,并对农田品质提出了检测与保护的重要参照依据。
In order to grasp the geographic quality and soil fertility resources of Shandan County in a timely and accurate manner.Make full use of the soil resources of Shandan County’s graded cultivated land reasonably through analyzing and studying the classification of cultivated land quality levels and the current status of cultivated land soil fertility in Shandan County.In such a way,we can understand the current status of cultivated land fertility in Shandan County in a timely and accurate manner and provide a scientific basis for its development.At the same time,it also provides countermeasures to improve the quality of cultivated land in Shandan County.Based on the relevant requirements of the national standard of cultivated land quality grade(GB/T33469-2016),we make full use of the GIS technology.The spatial structure analysis,hierarchical structure analysis and comprehensive index are used to make a comprehensive evaluation of the quality of cultivated land in Shandan County.The results of the evaluation and testing of cultivated land accurately and objectively reflect the quality level of cultivated land in Shandan County and provide an important reference basis for testing and protecting the quality of cultivated land.
