为了科学地掌握法库县耕地质量状况,合理利用耕地资源,依据国家标准《耕地质量等级》(GB/T 33469-2016),以Landsat 8遥感和土壤采样为数据源,运用RS技术、空间分析、综合指数和模糊数学模型等方法,对法库县耕地质量特征进行分析.结果表明,法库县耕地质量以三、四等级别为主,其他等级分布分散.针对有机质缺乏、绝大部分地块无灌溉条件、植被长势不明显等土壤障碍因素,建议采用工程、农艺、生物等措施,增加土层厚度,完善灌溉设施,改善土壤物理性状,稳定提高耕地生产能力.
Characteristic Analysis of Cultivated Land Quality Grade in Faku County based on RS
In order to scientifically and timely grasp the level of cultivated land quality in Faku county,and to make full use of the land resources,this study comprehensively used RS technology,spatial analysis,comprehensive index methods and fuzzy mathematics to e-valuate the quality of Faku county cultivated land taking Landsat 8 remote sensing and soil sampling as data sources,according to the"Cultivated Land Quality Grade"national standard (GB/T 33469-2016) .The results showed that the quality of the cultivated land was mainly in the third and fourth grades,and other grades were scattered.It was characterized by the lack of organic matter,the lack of irrigation conditions in most of the land,and the lack of obvious vegetation growth.In view of soil obstacles,it was suggested to a-dopt engineering,agronomic and biological measures to increase soil thickness,improve irrigation facilities and soil physical properties,and steadily increase the productivity of cultivated land.
