摘要
简述了植被盖度研究中提出的几种概念,介绍了地表实测植被盖度的几种方法,比较和分析了遥感图像解译植被盖度的植被指数法、亚像元分解法、混合光谱模型法和光谱梯度差法,对以后的研究方向作了一些展望。
The authors made a review on some concepts of vegetation coverage proposed in research work and presented some kinds of ground measurements of vegetation coverage.The method of vegetation indices,sub-pixel model,mixed-pixel model and spectra gradient difference model in the interpreter of vegetation coverage were compared and analysed respectively .The future trend of vegetation coverage study was analyzed.
