Those who live in under developed areas suffer the most from climate change. Either a water level rise in ice lakes, or a drought that lasts for weeks will bring a crushing blow to their lives.

那些生活在欠发展地区的人们是气候变化的最大受害者，冰湖水位的上升，或是数十天的干旱，都将给他们的生活带来会毁灭性的打击。

For example,a drought in the 1930s caused farmers to abandon their farms across the U.S.Midwest.The absence of crops intensified local soil erosion,leading to powerful dust storms.Large amounts of wind-swept dust traveled across the continent,caousing the infamous Dust Bowl and affecting air qualit,public health and patterms of human settlement throuhout the country.

比如，20世纪30年代的干旱迫使美国中西部地区的农民背井离乡；农作物的缺少加剧了当地突然的侵蚀，继而引发了严重的沙尘暴；大量风沙席卷整个美国大陆，形成了臭名昭著的干旱尘暴区，并对全国范围内的空气质量，公共健康以及人类的居住方式造成了负面影响。

The root biomass increased with high N and K applications under well-watered condition, but did not increase under water deficit condition.

复水后抗旱型品种的生长速率和干物质相对增长率在均高于干旱敏感型品种，而根系的生长抑制率低于干旱敏感型品种。

The precipitation was the main climate factor affecting interannual variation of soil water and land surface evaporation.

陇东黄土高原的土壤干旱化与地表蒸发关系不大，降水的逐年减少可能是土壤干旱化的根本原因。

陇东黄土高原的土壤干旱化与地表蒸发关系不大，降水的逐年减少可能是土壤干旱化的根本原因。

For slender branch sweet vetch which is up to 40.6% only, and analysis of variance proves that sand willow shrub forest reducing close stratum effect of wind speed has obvious advantages fully too. The seventh, there are many aspects of ecological benefit of city forest in arid and semi-arid areas.

第六、根据多目标灰色关联度评价结果，适应干旱半干旱风沙区城镇庭院绿化的针叶乔木树种为：云杉、落叶松和樟子松，其关联度评价值分别达到0.7720、0.7718和0.7622；落叶阔叶乔木树种为：山桃、垂柳、垂榆，其关联度评价值分别达到0.9554、0.8631和0.8362；花灌木树种为：玫瑰、沙地柏和黄刺玫，其关联度评价值分别达到0.7916、0.7730和0.7492。

Suiting for disposing in factory and suburb outer edge belts in terms of protection against wind and preventing sand from drifting, the tree is populous, and the bashes are sand willow and slender branch sweet vetch Among them, sand willow shrub forest in the nearly stratum 10cm layer, can decrease wind speed by 60.3%.

上述野 外试验和盆栽试验都证明上、下覆膜和美国干水处理保墒效果较好、性能稳定，可以在干旱半干旱地区城市森林植被建植过程中大面积推广应用。

It also suggested that the climate and environment in the area are characterized by changeability, sensitivity, instability, its general changes are the positive process of desertification correspondingly to the dry-cold steppe or desert steppe and desert, while the reverse process correspondingly to warm semi-humid forest steppe and temperate-humid shrub steppe.

进一步证实了古土壤S〓发育和河湖相沉积的萨拉乌苏组堆积时为温暖半湿润的森林或森林草原环境，全新世的砂质古土壤或湖沼相沉积时为温湿灌丛草原或疏林草原环境，黄土沉积时为半干旱干草原环境，风成砂沉积时为干旱荒漠草原甚至荒漠环境。

Dry land water Kiln is the kind of micro-catchment and conservancy project to retain water from running off and make full use of the natural precipitation so as to meet the needs of humanbeings, animals and crop production in dry and semi-dry land areas.

旱地水窑是干旱半干旱地区拦蓄地表径流，充分利用自然降雨以满足人畜生活用水和生产用水的一种微集水保水工程。

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.
