环保在我身边

正"目前,全世界每年约有4200多亿立方米的污水排入江河湖海,污染了5.5万亿立方米的淡水。""2005年全国废水排放总量为524.5亿吨,城市污水处理量仅为149.8万吨,其中工业废水占34%∽35%,城市污水占61%∽65%。"这些触目惊心的数字,向我们昭告了水污染的严重,可地球所受到的破坏还远远不止这些:土地的沙漠化、臭     

环保就在我身边

正我们所向往的环保,在实际生活中,就是社会的一种创新思维。能迸发出新的希望、新的生活、新的文明。简而言之,就是要按照简洁、实用的原则进行设计,减少多余的材料和能源的消耗,以及有害物质的排放。环保理念需要我们每个人从自身做起,解决资源浪费、环境污染的问题。我家里定期会有各种纸张、纸盒、购物袋、废旧塑料、饮料罐等,它们多被送去垃圾场。我想:"如果这些物品都能循环使用就好了。"于是萌生了把

爱护环境系列教育活动从身边小事入手

《幼儿园教育指导纲要（试行）》中明确指出：“在幼儿生活经验的基础上，帮助幼儿了解自然、环境与人类生活的关系，从身边的小事入手，培养初步的环保意识。”因此，我们围绕环境教育开展了很多主题活动，并收到良好效果。在近两年的实践和研究中，我们幼儿园课题组成员通过大量的教学活动、实验改革，初步研究出“生态环境”、“资源环境”、“周边环境”三大教育活动系列。1．爱护生态环境：保护动植物教育活动系列幼儿的天性是好奇的，他们对大自然的一切都充满着探索欲望。开展环保活动从保护动植物入手，培养幼儿自觉关心、爱护环境…     

炎炎夏夜,警惕路边烧烤污染身边环境

“绿树阴浓夏日长,楼台倒影入池塘。水晶帘动微风起,满架蔷薇一院香。”这是唐代诗人高骈《山居夏日》中对夏日美景细致入微的描述,字里行间流淌着夏天的宁静和清幽。但是,这对于身处现代社会的人们来说,似乎已成为遥远的记忆。“仲夏苦夜短,开轩纳微凉”,当您忙完一天的工作学     

身边的环保

曾经读过一段这样的文字:蓝色的海水孕育五光十色、性情各异的儿女——天蓝的、乳白的、金黄的、翠绿的、火红的、银灰的、墨黑的、淡紫的贝壳……这段文字使我对海产生了幻想,憧憬着有一天能走近它、抚摸它。 2001年9月,我被湛江师范学院教育系录取了。这让我有了走近海的

公众环境健康的现实启蒙——读《环境应知100问:您身边的环境知识》

<正>读了由环保部宣教司组织编写、中国环境出版社新近出版的《环境应知100问:您身边的环境知识》一书,颇有感触。这本书,切入点和主题都是公众环境健康。公众环境健康是新环保法提出的一个新理念。这本书实际就是对公众环境健康问题的解读。旧环保法曾提出"保障人体健康",而新环保法修改为"保障公众健康"。为什么要做这样的呢?过去讲,污染物质进入土壤、进     

Desertification around Hirakud reservoir

Summary A comparative study of Survey of India topo-maps of 1929 and land satellite imageries in False Colour Combination (FCC) of 1975 indicates a loss of 43% and 46% of the reserved forest around Sambalpur and Jharsuguda respectively, besides other forest types in a radius of twenty miles. Deforestation is found to be an accelerating process where the rate of loss is estimated to be more during 1970–75 and 1960–70 in comparison to 1950–60 from a semilogarithmic trend curve between 1929 and 1975. This curve also fits to a hypothesis that the rate of deforestation is faster after 1950 (after developmental plan periods came into force). An analysis of the climatic data indicates a decrease in rainfall and number of rainy days, and morning relative humidity. The mean minimum and maximum temperature, evening relative humidity and atmospheric pressure show increasing trends. Relationships between forest loss and climatic parameters are significant for morning relative humidity, rainy days, maximum temperature and atmospheric pressure. Considering the loss of storage capacity of the Hirakud reservoir due to severe deforestation in the catchment area, suggestions are given for natural forest preservation.

A wind resource assessment around large mountain masses: The speed-up effect

The wind potential around an intensely mountainous area has been studied and an experimental analysis is presented the output of which could be used in the wind farm planning procedure aiming at maximization of the wind power production output of an area. The wind speed of a chosen site of Central Greece was studied based on field measurements around a large mountainous area of Central Greece. Understanding flow in the foothills and the wider area of the mountains is of great importance for estimating wind resource in rough terrain. In this article, special focus was given to the speed-up effect and forced air flow around mountainous masses.

Overview of hypoxia around the world

No other environmental variable of such ecological importance to estuarine and coastal marine ecosystems around the world has changed so drastically, in such a short period of time, as dissolved oxygen. While hypoxic and anoxic environments have existed through geological time, their occurrence in shallow coastal and estuarine areas appears to be increasing, most likely accelerated by human activities. Several large systems, with historical data, that never reported hypoxia at the turn of the 19th century (e.g., Kattegat, the sea between Sweden and Denmark) now experience severe seasonal hypoxia. Synthesis of literature pertaining to benthic hypoxia and anoxia revealed that the oxygen budgets of many major coastal ecosystems have been adversely affected mainly through the process of eutrophication (the production of excess organic matter). It appears that many ecosystems that are now severely stressed by hypoxia may be near or at a threshold of change or collapse (loss of fisheries, loss of biodiversity, alteration of food webs).
