开垦土地

In an attempt to contain some of the disastrous consequences of strip mining. Congresspassed the Surface Mining Control and Reclamation Act of 1977.

在控制那些由露天剥采造成的灾难性后果的尝试中，议会于1977年通过了表层土地采矿控制与开垦的法案。

During his inaugural and the Governor's Conference held 2 days later, Roosevelt referred to problems of rural-industrial "imbalance" and the cultivation of "submarginal" lands.

完成就职演说，召开内部会议后仅两天，Roosevelt就总结了农村工业发展的"不平衡"和"边境"土地开垦等问题。

Some conclusions from the study on human driving factor are:(1) the human activity is much more active factor to the process of desertification which mainly incarnates on the changes of the landuse fashion (from traditional rangeland 100 years ago come to interlacing agro-pastoral region) and enhance of landuse intensity (over-cultivation, over-grassing and over-fuel collection);(2) the natural vegetation had been destroyed suicidally by human activities that had accelerated to the development desertification.

在人为驱动力的分析中，得到以下一些初步的结论：（1）人类活动是本地区沙漠化过程中更加活跃的驱动因子，体现在土地利用方式的转变（从传统的牧业草原到今日的农牧交错区）和强度的增加（过度开垦、放牧、樵采等）；（2）由此对自然植被群落毁灭性的破坏，加速沙漠化的进程。

Underutilization of relatively small but rich plots of land.

Virgin land: that without the cultivation of land, also refers to unexplored territory.

处女地 ：指未经开垦的土地，也指未探索的领域。

By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.

利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量，得出：天然灌木林地，受人为影响较小，每年有大量有机物质返还土壤，且天然灌木的根系可以很好的改良土壤的物理性质，同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分，土壤质量最好；农田受到的人为影响最大，但农田综合得分却好于人工柽柳芦苇地综合得分，这可能是由于在开垦初期的绿洲农田，受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致；乔木林地，由于人们用大水漫灌的方式灌溉，致使林地土壤变得板结，土壤物理性质下降，加上克拉玛依地区气候干燥少雨，一次灌溉后较长时间后才有下一次灌溉，致使土壤理化性质恶化，土壤质量不高。

And hence subduing or cultivating the earth, and having dominion, we see are joined together.

因此开垦或者耕种土地与拥有支配权，我们看出是连在一起的。

In turn, farmers are converting land formerly left untilled into cropland, and ceasing to rotate corn and soybean crops from year to year , in favor of corn.

与此相应地，农民们把先前留下来的未开垦的土地改造成玉米田地，停止了年年玉米和大豆的轮流更种，以便有利于玉米的生长。

A UN environmental assessment of the country estimates that productivity could be doubled on the land currently farmed, while another 10% of Afghanistan (approximately 62,000 square kilometres, or 24,000 square miles) could be brought under the plough through irrigation.

联合国的环境评估认为，如果阿富汗那10%无人耕种的土地（有将近62000平方千米，或者说24000平方里）能够被开垦和灌溉，那该国的生产力将能翻倍。

The procedure, from budding to grow up, is a significant difference in every different land use type. It's very difficult to invade into the natural forest without any disturbance; For the sake of failure forestation and reclamation, L. lucocephalla and intolerant spices will invade into mixed woodland, and it will be a new dominant after competition finally; They has a high probability for invasion a..nd spread at abandon rural and graze land. The spread area of L.

种子萌芽到成株的过程中，因土地利用类型不同有显著差异，未经干扰之天然林银合欢无法入侵；次生林地由於造林失败或开垦之原因，银合欢与其他阳性树种一起入侵，经过生长竞争后，银合欢会逐渐成为优势树种；而休耕之裸露地或停止放牧之草生地，银合欢之入侵及扩散机率最大。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
