The area of severely degraded grassland had increased to 818.97 km 2. In some places and in some periods overstocking did occur, but the grassland as a whole was not overgrazed. The degradation of local grasslands could be due to the...

在个别地区、个别时间、局部草地有超载，但从整体上讲，整个草地并不过牧；全球气温升高所引起的荒漠化，应是处于半干旱—半湿润干旱区的达日县草地退化、大片黑土滩产生的主要原因。

Of course, there may be interaction between overgrazing and climate change.

但气候的干旱化给过牧对草地的影响起到了推波助澜的作用，其叠加效应加速了草地的退化沙化。

It is such a cycle that has led to widespread desertification in some parts of the world, primarily through overgrazing that can be compounded by naturally occurring droughts.

这样的循环导致在世界的某些地方大范围的人为沙漠化，这主要是由于过度放牧并伴随着自然干旱的发生。

But due to economic profit, human being have been overusing water resources so that bring about a series of ecological environment problems, which have hold up development of economy.

但是长期以来，由于气候干旱以及在市场经济利益驱动下所形成的人类对水资源的过度开发利用，导致了一系列阻碍区域经济发展的严重生态环境问题。

The content of unsaturated acids was increased under 70% water supply and dry treatment in growing stage, while that of saturaled acids decreased. Under 70%￣55% water supply and dry treatment at podding the content of unsaturated a...

结果表明。70％～55％供水量及荚期干旱不饱和脂肪酸含量最高，饱和脂肪酸、亚麻酸含量最低、最有利于大豆油质的改良。

The yield was sensitive to water supply during flowering and podding stage, in which the sensitivity was found podding stage （ R3 - R5 ）〉 flowering stage （R 1 - R3 ）〉 vegetative stage （V2 - R1 ）〉 the contribution of water supply to the yield formation was more central than potassium fertilizer application in light of controlling soil water at the same growth stage.

大豆对水分较为敏感的时期是开花期和结荚期，各时期敏感程度表现为结荚期〉花期〉营养生长期；同一生育时期控水下水分对大豆产量的影响要高于钾肥；旱涝都将影响大豆籽粒产量的形成，但干旱引起的减产程度要大于涝害。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
