地面植被 meaning in English
ground vegetation cover
ground vegetative cover
Examples
- Estimating the number of rare species in woodland vegetation by multisampling
对地面植被群落中稀有植物的种类数的多重抽样估计 - We created a system in rome : total war that let us define each climate and assign a set of vegetation to each one
我们在罗马：全面战争中创建了一个系统，让我们定义每一种气候，并给之安排一系列的地面植被。 - Roadbed construction on permafrost will give substantial disturb for the heat and mass transfer balance between the ground surface and atmosphere , usually , roadbed construction increases the amount of absorbed heat via vegetation removal , solar radiation and increased role of water activities in the adjoining area , then cause the local degradation of the permafrost underneath , as a result may lead to damage of the roadbed
多年冻土区道路的修筑，改变了原来天然地表与外界的热交换关系，通常由于地面植被的破坏、太阳辐射和水的影响，导致进入地层中的热量增加，引起多年冻土区冻土的融化，从而导致路基面破坏。 - Because of a little studies on the relationship of the biodiversity of yellow river delta with abut regions by yellow river been made , based on the existing researches and the investigating on ground vegetation in sep . 2003 and oct . 2004 , we statistically analyzed the flora composition and the biodiversity correlation between yellow river delta and the abut regions
鉴于已有的研究工作对黄河三角洲地区生物多样性通过黄河与周边地区的联系方面的研究相对薄弱，以现有研究工作为基础，以黄河的廊道作用为主线，并结合2003年9月和2004年10月两次实地地面植被调查，主要对黄河三角洲自然保护区的植物区系组成状况进行统计分析，总结出黄河三角洲地区生物多样性状况、植物区系组成的特点及其与周边地区的相互关系。 - Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation . it is optimal for mapping forest structure . the return waveform and the processing method are described . the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects . the clumping caused that structure parameters are different from the actual value . to solve this question , a model by 3 - d canopy structure parameters is needed
星载激光测高仪的回波信号能够灵敏反映地面植被组成和地表高度的变化,因此能够用于探测森林地貌;首先对星载激光测高仪的森林回波信号及其处理方法进行了介绍,探讨了在不考虑植被聚集情况下,植被组成与回波信号之间的关系;由于植被的聚集效应,例如树叶群集成树冠,会导致植被组成参数与真实值之间存在差异,这需要建立关于三维的空间分布模型加以解决。
