The long-term solution to this challenge has to be energy conservation and substitution. To sensationalize the expansion of oil consumption and importation of certain developing countries will only serve as factors of more turbulent oil market that may generate even higher price prediction and pressure.

要应对高油价的挑战，长期的应对措施自然是节能降耗和寻求替代能源，任何对新兴发展中国家能源消费与进口增长的炒作和夸大，都只会增加国际石油市场的不稳定性，并转化为高油价预期，从而进一步加大油价上涨压力。

In the US, however, the Department of Agriculture has decided against allowing land to be released early from the Conservation Reserve Program that, similarly to the EU's set-aside, pays farmers not to plant on some of their arable land.

It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Moreover, China has unfolded large-scale projects for water and soil conservation throughout the country, and constructed a shelter-forest network for fields in the plains to control soil erosion.

在全国范围内开展了大规模的水土保持，建设平原农田防护林网，治理水土流失
