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.
