摘要：全球人口不断增长，耕地资源越来越紧张，传统农业土地资源调查方式没法及时覆盖所有区域，满足不了精准农业管理和可持续发展决策的实际需求。遥感技术能从宏观角度快速、定期开展观测，为农业土地资源的动态监测与评价开辟了新的技术方向。本文利用多时相、多光谱遥感影像数据，搭建起一套适配农业土地资源动态监测与评价的技术框架。解析不同作物生长季的植被光谱特征变化，准确识别耕地利用类型及其空间分布，结合时间序列遥感数据，分析研究区农业土地资源的时空演变规律，明确土地利用强度与覆盖变化的动态趋势。本文从土地适宜性、利用效率及生态稳定性三个维度，搭建综合评价指标体系，系统评估区域农业土地资源的质量状况。

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.
