英语翻译
In the past 50 years,China has improved a total of 670,000 sq km of soil-eroded areas,and the forest coverage rate has increased to 13.92 percent.Some achievements have also been made in natural environmental protection,with 151 model ecological zones established.There are 1146 nature reserves across the country,including 137 national nature reserves.The largest project for the transformation of the ecological environment is the “Three-North” Shelterbelt Project.Following the beginning of the construction of this 7,000-km “Green Great Wall” in 1978,more than 18 million hectares of areas had been afforested,21 million hectares of fields protected by trees and about 20 percent of desertified land improved by 1996.The construction of another two projects---- the shelterbelts on the middle and lower reaches of the Yangtze River and the coastal shelterbelts---- is being speeded up.At present,China’s natural ecological environment is still poor.Water loss,soil erosion,desertification and degeneration of grasslands are worsening with each passing day,which weakens the ecological functions of windbreaks,sand fixation,water storage,soil preservation,and the protection of biological diversification.Hence,the Chinese government is taking measures to implement the National Program for Improving the Ecological Environment in an all-round way,while paying great attention to the prevention and control of pollution and the protection of the ecological environment.
Prevention and Control of Pollution
With respect to the prevention and control of industrial pollution and the comprehensive improvement of the urban environment,China is trying to promote environmental protection by improving its supervision,management and technology.In 1999,China completed 22,358 environmental projects,involving a total investment of 12.31 billion Yuan.A total of 2,364 smoke-and-dust control districts were set up in 536 cities and a total of 2,040 noise-standardized areas were established in 431 cities.The 144 enterprises by Dianchi Lake,each pouring over 100 tons of wastewater daily into the lake,have been ordered to make improvements within a set time.The same is true of the 109 enterprises by Chaohu Lake,each pouring over 100 tons of wastewater into the lake daily.As a result,the rate of industrial pollution emission along the valleys of Dianchi and Chaohu lakes has reached the standard,and the water quality has greatly improved.

在过去50年来,中国已有所改善,共67.0万平方公里的水土流失区,森林覆盖率已增至百分之13.92 .一些成就也取得了自然环境的保护,与151个生态示范区的建立.有自然保护区1146年在全国各地,包括137个国家自然保护区.最大的项目为改造生态环境是“三北”防护林工程.之后开始建设的这7000公里的“绿色长城”于1978年,超过18万公顷的地区已造林21万公顷的保护领域的树木和约百分之二十的荒漠化土地改良,到1996年.建造另外两个项目----防护林上中下游长江和沿海防护林----正在加快.目前,中国的自然生态环境仍然很差.水土流失,土壤侵蚀,防治荒漠化和草原退化正在恶化日新月异,这削弱了生态功能的防风林,固沙,蓄水,土壤保护,以及保护生物多样化.因此,中国政府正在采取措施,落实国家计划改善生态环境,全面的方式,同时高度重视预防和控制污染和保护生态环境.
防止及控制污染
关于预防和控制工业污染和全面改善城市环境,中国正试图促进环境保护提高其监督,管理和技术.在1999年,中国完成了22358环保项目,涉及总投资123.10亿人民币.共有2364烟雾和粉尘控制区建立了536个城市和2040年共噪声标准的地区设立了431名城市.在144个企业的滇池,每个浇注100吨以上的污水每天都到湖边,已下令进行改进在一个设定的时间.同样的企业由109巢湖,每个浇注100吨以上的污水进入湖每天.因此,为工业污染排放沿滇池流域和巢湖湖泊已达到标准,水质已大大改善
