周围地形 meaning in Chinese
surrounding topography
Examples
- Study the landform effects on the diffuse irradiation . when integralling the visible vault of heaven , it is necessary to estimate the shadow status on every direction in 2 circle . the slope and aspect are also effective
2 、地形因子的影响在对“可见”天穹积分时，对2范围内各方向上的遮蔽状况进行判断，确定每个方向上由前方地势所造成的遮蔽角度，从而反映周围地形造成的遮蔽影响，实现对“可见天穹”的积分。 - To the influence of the plateau terrain , the impact of the elevation and the roughness of terrain to every energy component out and incoming are study , and basing the soil spectrum model proposed above , a new radiative transfer model of terrain area was put forwarded in which the soil water content , lai , terrain roughness and elevation were considered synchronously , and incoming scatter light was integral with the solid angle of semi - globe space defined by the slope of the pixel , so scattering lights of terrain and the sky are properly considered , but the operation is still within the acceptable range
地形与反射率的关系是本文研究的一个重点。本文对崎岖山地象元的各入射光和反(散)射光分量进行了深入分析，在所提出的湿润土壤光谱模型和植被冠层模型的基础之上进一步提出了新的适合青藏高原的山地辐射传输模型。该模型同时考虑了土壤含水量、植被覆盖( lai ) 、地形起伏和海拔高度的影响，并以象元坡面定义的半球空间立体角对环境入射光进行积分，使周围地形和天空散射光均得到适当考虑，计算量又在可接受范围内。
