在苇丛坐下,打开随身携带的《诗经》,翻到《秦风·蒹葭》。蒹葭丛中读《蒹葭》,真是亲切,就觉得是回到了诗的故乡,回到那个遥远而古老的年代。一有时候,就觉得,假日行走,若是随身携带一卷《诗经》,也许常常会在不经意间,就撞醒一个沉睡千年的美丽意象,闯进一片久蕴心头的奇妙意境,让你的旅行多一种诗意的愉悦和难以言表的快感。呱呱——唧啾,呱呱一一唧啾,……一串清脆的鸟呜,将您从酣睡中唤醒。睁开眼,窗前已是阳光灿烂。这是一个春天的假日,原计划要读读《诗经》的,何不到室外去读呢?于是操书出门,乘着和风,循着鸟声,不知不觉间,已来到一条河边。河心沙洲上,正有一对美丽的小鸟,相对而鸣。呱 相似文献

贵州省铜仁市的梵净山是五陵山脉主峰,凡九十九溪,八面射出,水随山势,湍急异常。它们泛着泡沫,一刻不息,遇到百尺高坎,也像早有准备,从容跳下。水落石出,巨如房、细似末,被溪流冲得千奇百怪,刷得干干净净。这坦率、纯洁、热情的溪,则永远呐喊、狂奔…… 相似文献

世界文学大师雨果说:"大自然既是善良的慈母,同时也是冷酷的屠夫。"近年来,人类由于对环境不够珍惜,随心所欲,滥伐林木,滥建厂房,生存环境遭到了严重破坏,各种环境问题接踵而至:森林退化,沙尘暴扬,水土流失,洪水肆虐,海啸怒吼,河流干涸,酸雨赤潮,臭氧空洞……空中烟囱林立,浓烟滚滚,河中死鱼漂荡,污水滔滔;地上垃圾遍布,废渣成堆……抬头观污 相似文献

深谷怪声天气有些反常。"谷雨"以后,气温仍然偏低,倘若在以往,早该进山采茶了。直到"立夏",我才与两位朋友驱车来到百里之外的深山采茶。这儿地处大山前怀,背凤朝阳,气温偏高,都怪异地春温不等,再加上我主观臆断推迟此行,导致山茶略老。山茶生长在巨石杂陈、落差较大的谷底溪床上,与野蔷薇混为一处,山溪上下,比比皆是,团团嫩绿,葳蕤生光。两位朋友是夫妻,首次采茶,甚是愉悦,便如鸡啄米般采了起来。我酷爱爬山,又是采茶老手,深知山高风烈,越往上走气温越低,山谷尽头的山茶正当时,索性舍近求远。我跟朋友说明情况,要他们优中选优,溯流而上,在山半腰汇合。言罢,背上行囊,沿着羊肠小道独自爬山。 相似文献

建立水质自动监测系统是继我国设置大气污染自动监测系统之后,进一步强化对江河湖海实施水质监控的重要举措。水质自动监测具有连续及时反映水质的动态变化、加强快速处理应急事件的优势,它的发展将逐步实现由人工间断监测向自动连续监测的过渡, 相似文献

The spectre of regulatory reform carried out in a range of Western countries has generated concern amongst parts of the environmental policy community. Quality and effectiveness are said to be at stake, but empirically there is a dearth of data on the relationship between provisions for quality control and the effects on quality and effectiveness. This research addresses this lacuna by analysing the effects of different quality control provisions in the Netherlands and Denmark for a globally institutionalized environmental appraisal tool—Environmental Assessment (EA). Extensive technical provisions for quality control in the Netherlands have led to it being described as the ‘Rolls Royce’ of EA systems, while in Denmark the polity is expected to take charge of quality control. The effects of quality control are investigated through surveys and in-depth interviews with actors centrally engaged with EA implementation. The results show that quality control provisions are poorly related to the perceived quality and effectiveness of EA. Only the appropriateness of the scope of EA reports is perceived to be strongly related to quality control provisions. The findings are relevant for environmental policy communities concerned with quality control systems and effectiveness of policy appraisal tools and policy-makers contemplating regulatory reforms. 相似文献

Abstract: There is a significant need for a science‐based approach to interpret water‐monitoring data and to facilitate the rapid transfer of information to water resource managers and the general public. The water quality Index (WQI) is defined as a single numeric score that describes the surface water quality condition at a particular time and location. The objective of this paper is to describe the WQI concept and the approach for developing an ecoregion‐specific standardized WQI that meets the needs described above. The premise of the proposed WQI is based on categorizing scientifically documented aquatic life responses to changes in instream water chemistry. The method uses an aggregated procedure that matches the entire range of standardized probable biological responses to standardized narrative water quality evaluation categories and standardized rank score categories. The calculation of WQI and decision‐making process are performed within an Excel spreadsheet software program. The article includes examples of the proposed WQI applications that could enhance effective water resource management and facilitate timely communication of water quality conditions to water resource managers and the general public. 相似文献
