1·The climatic changes in southwestern Asia were more subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover.

亚洲西南部的气候变化更为微妙，因为它们涉及到山地雪线、降雨模式和植被覆盖率的变化。

2·The consequences of an excessive number of livestock grazing in an area are the reduction of the vegetation cover and the trampling and pulverization of the soil.

在一个地区过度放牧的后果是植被覆盖的减少和对土壤的践踏和粉碎。

3·Poor vegetation cover, serious soil erosion.

植被覆盖差，水土流失严重。

4·The surface temperature of vegetation cover and bare land have biggish variation.

裸地和植被浅层温度变化平缓。

5·Soil erosion in the loess area relates to low vegetation cover rate in this region.

黄土高原地区严重的水土流失与该区植被覆盖率低有密切的关系。

6·On the whole, during the nearly 30 years, the vegetation cover hes shown an increasing trend.

近30年间，三峡大坝植被覆盖度整体上有增加的趋势。

7·Unreasonable land use and decrease of vegetation cover may have amplified soil erosion in some extent.

不合理的土地利用和地表植被覆盖的减少对土壤侵蚀具有放大效应。

8·Vegetation cover index decreases by a big margin, indicating that the vegetation cover reduces obviously.

两年的植被覆盖指数相差较大，说明植被覆盖减少显著。

9·The results show that the variations of precipitation and temperature are connected with vegetation cover.

结果表明降水和温度变化与植被复盖度有关。

10·MODIS vegetation index is a factor of the best indicators between state of vegetation growth and vegetation cover.

MODIS植被指数是植被生长状态及植被覆盖的最佳指示因子，也是季节变化和人为活动影响的重要指示器。

植被

1·Vegetation cover is an important component of environmental factors, and is also the best indication to reflect the regional ecological environment.

植被是环境的重要组成因子，也是反映区域生态环境的最好标志之一。

2·Semi arid climate, poor vegetation cover and highly erodible loess can be regarded as the main natural factors responsible for the formation of hyperconcentrated flows in the Loess Plateau, China.

黄土高原半干旱的气候条件、稀疏的植被和疏松易蚀的黄土物质，是该地区高含沙水流形成的自然地理因素。

3·Furthermore, the geographical distributions of the ice sheets, vegetation cover and coastlines during the ice age are well mapped.

另外，冰期时的冰原、植被与海岸线的地理分布也已经绘测完成。

4·We conjecture that the increased vegetation cover result in improved leaves albedo, and then the reduced the solar radiation reaching earth surface.

这可能与植被的叶面反射率增加导致了到达地表的太阳辐射量减小所致。
