植被覆盖度及其测算方法研究进展

植被是陆地生态系统的主要组份、是生态系统变化的指示器。植被覆盖度作为植被生长状况的直观量化指标,在水文、气象、生态等方面的区域或全球性问题研究中起越来越重要的作用,植被覆盖度的测算是否精准很大程度上影响着相关研究结论是否科学合理。本文综述了植被覆盖度在自然地理研究中的应用情况,分类归纳了植被覆盖度的测算方法,并分析了各种方法的特点、优势及其存在的问题,同时指出了植被覆盖度测算方法今后的发展趋势和研究重点。

Review of vegetation covering and its measuring and calculating method

Vegetation is the main component of terrestrial ecosystem and the indicator of ecosystem change.As the quantity index of vegetation's growth status,vegetation covering plays an important role in the regional and global researches of several fields,such as hydrology,climate and ecology.The results of measuring and calculating vegetation covering deeply affect conclusions of related study.Based on reviewing these methods and their application fields,this paper analyses peculiarity,advantage and shortage of each method.At the same time,the paper indicates the research emphases and current henceforth of the vegetation covering.
