我们认为原因是复杂的，但以植被及相对海拔高差影响比较突出。
The reason is complex but the effect of the vegetation and relative elevation is comparatively intcnsive.
山体坡面不同坡位下土壤质量综合指数(P i)研究表明土壤质量指数随山体坡面位置相对海拔高度的降低而增高。
The research of the composite index number (PI) of soil quality in different soil locations suggests that, the soil quality index increases as the altitude of mountain slope location decreases.
苏加塔谷底部相对平坦，海拔约300米(1000英尺)。
The Suguta Valley floor is relatively flat and stands at an elevation about 300 meters (1, 000 feet) above sea level.
“这种鹿相对来讲，可能在苏门答腊岛上某特定海拔之上比较普遍，”Timmins在他威斯康辛州麦迪逊市的基地说，“我一直怀疑它们仍然在这片区域里生存着。”
"This deer might well be relatively common in Sumatra above a certain altitude," said Timmins, speaking from his base in Madison, Wisconsin. "I always suspected it still survived in the region."
我没有任何麻烦调整到海拔相对节流阀命令。
I don't have any trouble adjusting to the altitude-relative throttle commands.
随着海拔梯度的上升，资源植物的区系成分、性状特征表现出相对应的垂直分异规律。
With increased elevation above sea level, the flora components of the resource plants present corresponding vertical differentiation patterns.
恩，阅读部分忘掉了一个事实，那就是在温暖的海拔低处，黄杉死亡数量比相对寒冷的高海拔地区要多。
Well, the reading passage forgot to take one fact into account. Many more trees are dying in the lower elevations where it is warmer than in the higher elevations where it is cold.
从空间分布看，NDVI高值区与水源、海拔高度和植被类型有很大关系，在水源附近区域ND VI值相对较高，草甸型草场NDVI值最高。
The high value of NDVI has close relationships with water supply, altitude and vegetation types, so NDVI is relatively high near water sources and is the highest in meadow grassland.
年降水量变异系数随海拔的升高而减小，即海拔越高的区域降水量的年际间波动相对越小。
Annual precipitation variation coefficient was smaller in higher altitude mountain than in lower altitude areas and plain in Urumqi river basin.
中等海拔处每基株含有的分株数较少，海拔较低及较高处相对较多。
Sites at mid-altitude had lowest stems per individual, whereas more stems per individual were found at lower or higher sites.
我不得不承认，在智能和AP模式中使用的350QX2的海拔相对油门输入使它很容易保持一个稳定的高度为好。
I have to admit that the 350QX2's altitude-relative throttle inputs used in Smart and AP modes make it really easy to hold a steady altitude as well.
