Post-war agriculture in Britain and the EEC, facilitated by new technology and state support, has been very successful in increasing food supplies to a level where most products are now in surplus.Substantial environmental impacts have resulted, particularly habitat and species loss and pollution from pesticides and nitrogen fertilizer. Problems of soil compaction and erosion have not been widespread but concern is growing over the increasing incidence of soil erosion.Policy measures are now being implemented to reduce production by switching some state support for agriculture from production to environmental management.Production can be reduced either by a return to lower-input/output systems, or by taking land out of farming use. There is a vigorous debate in the environmental movement as to which strategy, or mix of strategies, would maximise environmental benefits.

1.英国和欧洲共同体国家战后农业在新技术的推动和官方支持下,在增加粮食供给方面取得了很大的成功。目前,大多数产品已是供大于求。 2.大量的环境影响已经产生,特别是物种和栖息地的丧失,以及农药和氮肥应用所造成的污染问题。土壤板结和侵蚀虽不广泛,但土壤受侵蚀状况正日益增加,已引人们的关注。 3.正在实施降低农业生产力的政策,将政府对农业生产的部分资助转用于环境治理。 4.降低农业生产力,可通过退回到低投入、低产出的农业模式,或通过退耕来实现。最终应采取哪一种政策,以保证获得最好的环境效益,在当前环境界引起了一场激烈的争论。

Through the field investigation, it showed that the wintering habitat of certain rare birds remain Steadily and unchangeably for many years because of favorable food condition, i. e. the subterraneous corms of Scirpus mariqueter. In the outer zone of S. mariqueter community, the subterraneous corms grow well and the output is wealthy. The wintering habitat if located in the outer zone of the intertidal flat where sedimentary rate of mud and silt if higher, and between two large tidal channels sedimentary rate...

Through the field investigation, it showed that the wintering habitat of certain rare birds remain Steadily and unchangeably for many years because of favorable food condition, i. e. the subterraneous corms of Scirpus mariqueter. In the outer zone of S. mariqueter community, the subterraneous corms grow well and the output is wealthy. The wintering habitat if located in the outer zone of the intertidal flat where sedimentary rate of mud and silt if higher, and between two large tidal channels sedimentary rate reached the highest. The activity of tidal current is favoured for deposition of mud and silt on this beach. These are the natural environmental factors advantaged for rare birds wintering.

珍禽越冬栖息地多年保持稳定不变的原因,除由生境所能提供的食料——海三棱藨草的地下球茎所决定外,根本原因在于地下球茎最发育的滩段,是在海三棱藨草群落的外带,是低潮滩向高潮滩演替过程中淤涨速率最快的滩段。其潮汐水动力条件有利于淤涨;大型潮沟的限定,更保护和保证了滩涂淤涨速率。这多种自然环境因素,决定了珍禽对越冬栖息地的选择。

The Rainbluc Swan Reserve lies in the middle part of the Tianshan Mountains (The Heavenly Mountains), between 420°28"-43°25'N and 83 °02'-86°00' E.

Meanwhile an environmental impact assessment work was done in 1988 prior to the project starting.

The Rainbluc Swan Reserve lies in the middle part of the Tianshan Mountains (The Heavenly Mountains), between 420°28"-43°25'N and 83 °02'-86°00' E. According to the local government's construction plant a reservior, namely "Husdashely" of 10.2 × 108m3 in extent would be cinstructed in the center of the Reserve. Meanwhile an environmental impact assessment work was done in 1988 prior to the project starting. The result of prediction showed that if the reservior had been built, the ecological environment of the Reserve would have been destroyed though economic benefit of the reservior was high. Finally the local government accepted the environmental assessment statement, and the Reserve was preserved.

本文评价拟建呼斯台西里水库工程对巴音布鲁克天鹅保护区生态环境影响,认为虽然水库经济效益很高,但对生态环境破坏严重:(1)将淹没385km~2优良草场;(2)使美丽的开都河曲流景观消失,影响旅游事业发展;(3)淹没保护区核心区9/10的天鹅繁殖区和7/10的天鹅栖息地,会使天鹅数量迅速下降,估算蓄水当年在大尤尔都斯盆地天鹅将减少65%.
