摘　　要：植被覆盖度是描述陆地表面植被特征的一个重要参数。快速准确的测量植被覆盖度,对研究植被覆盖与土壤侵蚀关系,植被覆盖的水土保持效益,以及土壤侵蚀预报等具有重要意义。在多年实践的基础上研制出的便携型植被覆盖度摄影仪,适用于野外平地或山坡的植被覆盖度的照相测量,能方便地调节相机距地表面高度和增强相机的拍摄稳定性。同时开发了便携型植被覆盖度摄影仪的配套软件——植被覆盖度自动计算系统(PCOVER),能对获取的植被图像进行自动判读并估算植被覆盖度,实际应用显示有很好的判读精度。Coverage is a very important parameter for describing the vegetation characteristics of land surface. Determining vegetation coverage quickly and exactly is important to research the relationship between vegetation coverage and soil erosion,benefit of soil and water conservation from vegetation coverage,and prediction of soil erosion.The portable photographic instruments for vegetation coverage,which had been developed through several years practice,was adaptive to determine vegetation coverage by vertical...
