摘要: 作物覆盖度是农业生态学、作物栽培学和水土保持学等学科中的重要研究参数,因此如何快速和准确地地获得覆盖度数据对相关科技工作者具有实用价值。本文综述了国内外的作物覆盖度的近地面观测方法,将其归纳为三大类:地面实测类、动态模型类和遥感类,提出并评估了利用叶面积指数推导作物覆盖度的模型法。同时,在分析各种方法的特点和优势的基础上,对不同情形下的覆盖度方法的使用提出建议,最后对作物覆盖度测量方法可能的发展与研究方向作出了展望。以期为相关研究人员快速获得适宜的观测方法和方案提供参考。

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.
