Abstract:

Cultivated land is one of the major natural resources of agricultural production development. Cultivated land fertility is a main index in the characterization of farmland quality, and it has direct impact on the development of agricultural production. The construction of cultivated land fertility evaluation index system is the key to ensure the rational utilization of farmland, which is of great significance to the protection of cultivated land, the improvement of soil fertility and the development of agricultural production. In this paper, the relevant research of cultivated land fertility assessment at home and abroad was briefly introduced. Furthermore, the development history, advantages and disadvantages of eight major technologies and methods widely used in cultivated land fertility assessment at home and abroad were summarized. The available research results show that the traditional evaluation methods have some limitations, and the laws and regulations need to be improved. With the rapid development of computer network technology and GIS technology, artificial intelligence method and GIS-based data mining method will gradually become the research hotspot, and the application of GIS and satellite remote sensing technology will be more extensive and could improve the accuracy and timeliness of farmland information. Based on the review conducted by this study, it is expected to provide theoretical and technical support for the Third National Soil Survey, as well as the development of profitable, ecological and sustainable agriculture.

Key words: cultivated land, soil fertility evaluation, GIS, evaluation method, index system construction, research progress
