Abstract：With the continuous growth of the global population and the growing shortage of cultivated land resources, the traditional agricultural land resource survey method can not cover all regions in time, which can not meet the actual needs of precision agriculture management and sustainable development decision-making. Remote sensing technology can carry out rapid and regular observation from a macro perspective, and opens up a new technical direction for the dynamic monitoring and evaluation of agricultural land resources. This paper uses multi temporal and multi spectral remote sensing image data to build a technical framework for dynamic monitoring and evaluation of agricultural land resources. The changes of vegetation spectral characteristics in different crop growing seasons were analyzed, and the cultivated land use types and their spatial distribution were accurately identified. Combined with time series remote sensing data, the spatio-temporal evolution of agricultural land resources in the study area was analyzed, and the dynamic trend of land use intensity and coverage change was identified. This paper builds a comprehensive evaluation index system from three dimensions of land suitability, utilization efficiency and ecological stability to systematically evaluate the quality of regional agricultural land resources.
