摘要
植被是生态系统的重要组成部分,具有调节水文、气候和生态平衡的功能。植被指数是反映地表植被状况的重要指标之一,包含着植被90%以上的遥感信息,可以增强植被信息并削弱非植被信息的干扰。系统总结了全球54种主流植被指数的发展历程、影响因素以及分类体系,描述了其计算公式,并对其应用特点进行了评估和分析。指出未来植被指数的研究应该建立更加完善的汇总体系,关注植被指数的应用特点及应用方向,为生态研究、生产实践等提供理论基础。
Vegetation,as an important part of the ecosystem,has the role of regulating hydrology,climate and ecological balance.Vegetation index is one of the important indicators to reflect the vegetation status and contains more than 90%remote sensing information,which can enhance the vegetation information and weaken the interference of non-vegetation information.This paper systematically summarizes the development history,influencing factors and classification system of 54 global mainstream vegetation indexes,describes their calculation formulas,and evaluates and analyzes their application characteristics.It is pointed out that the study of vegetation index in the future should establish a more perfect summary system,pay attention to the application characteristics and direction of vegetation index,and provide a theoretical basis for ecological research and production practice.
