中文摘要：

三维绿量LVV突破了二维绿化指标的局限，可以更加准确地反映植被区域空间构成的合理性。本文研究利用遥感图像光谱信息与植被三维绿量之间的关系，以京港澳高速长潭段为试验区，构建基于遥感和地形因子的高等级公路路域三维绿量HLVV模型。结果表明模型计算与现场试验结果吻合较好，用其估算路域三维绿量可行，有助于客观评价路域生态环境。

英文摘要：

The Living Vegetation Volume（LVV） has broken the limitations of the two-dimensional index, reflecting the rationality of forest spatial composition more precisely. Taking the Changtan section of Highway G4 as the test site and making full use of the relationship between the spectral information of RS images and the Living Vegetation Volume, the paper studied to build the Highway Living Vegetation Volume model. The result showed that the model could fit to the field test result well, which verified its feasibility in estimating highway living vegetation volume, and would be helpful for objectively assessing the highway ecological environment.
