Abstract:

This paper aims to systematically analyze the application potential of remote sensing technology in constructing the agricultural resources ledger. By analyzing the literature, this paper expounded the agricultural resources ledger's research status, analyzed the development trend of remote sensing data source and monitoring technology in agricultural resources, and judged the application potential of remote sensing technology in the construction of agricultural resources ledger. The construction content of agricultural resources ledger mainly included inventory and evaluation of agricultural resources, which had space and time attributes. For agricultural remote sensing technology, apparent trends were favoring high spatial resolution, high temporal resolution, and high spectral resolution in the data source, and multi-source remote sensing data fusion application, intelligent remote sensing classification and efficient calculation of massive multidimensional data in monitoring technology. With remote sensing technology, the information of main agricultural natural resources and socio-economic resources in the inventory of agricultural resources could be obtained, and it also had great potential for the component evaluation of agricultural resources and the overall evaluation of agricultural ecosystem. Generally speaking, the content of agricultural resources ledger construction is constantly enriched, and the application ability of remote sensing technology in agricultural resources ledger construction is significantly improved, and its application potential still has a great room for improvement, which plays a positive role in efficiently developing agricultural resources ledger construction.
