Abstract: Crop coverage is an important parameter for studies in agriculture ecology, crop cultivation and soil and water conservation. Therefore, it is very valuable for the related scientists to observe the coverage data quickly and accurately. In this paper, the global observation methods of crop coverage near surface are summarized. The methods were classified into three categories: ground survey, dynamic model and remote sensing category. Moreover, we proposed and evaluated a model method for estimating crop coverage by using leaf area index.Besides, on the analysis of the characteristics and advantages of various methods, we suggested the suitable observation methods of crop coverage under different circumstances. Finally, the possible development and further research on crop coverage measurement are prospected. In all, it is expected that this paper can provide a reference for the relevant researchers to quickly obtain suitable observation methods and solutions.
