北京市西城区是全国最早的可持续发展综合实验区之一,区政府、教育局很早就提出要对全区中小学生进行环境教育,并在各方面给予了高度重视和支持。 1998年区政府、区教育局与北京教科院联合开展了联合国教科文跨学科项目“环境、人口与发展”(简称 EPD)的研究工作。全区有 30所中小学参加,研究的重点是探究中小学环境教育、人口健康教育促进社会可持续发展的途径与方法。 为了进一步提高全区环境教育的实效性,了解区内 EPD实验校教师环境教育能力的现状,并以此作为项目下一阶段教师培训内容与方法的依据,进行了有关实验校教师… 相似文献

正我国开展环境教育已有三十多年了,针对中小学生环境教育的讨论主要集中在城市地区,并取得了一定的成效,积累了很多经验,但针对农村特别是西部农村的中小学环境教育的研究还比较薄弱,学生的环境意识较低,教师对环境教育概念还比较模糊,环境教育专业能力较弱。因此,如何解决西部农村小学环境教育问题,提高西部农村中小学的环境教育水平已迫在眉睫。目前西部农村中小学环境教育存在的主要问题表现为:一是观念落后环境意识不强。当地教育主管领导、学校领导到教师、学生对环境教育的认识都不够,认 相似文献

乡村师范生环境意识的调查 总被引:5,自引:0,他引:5
调查的目的和意义中等师范学校是培养小学教师的摇篮,中师生的环境意识水平的高低直接影响未来小学生的环境意识的发展。并且中等师范学校没有升学压力,学生的课业负担较轻,在进行环境教育方面具有其他学校所无法比拟的优势。但乡村师范因地处县城或乡镇所在地,属于驻地方单位,行政上归上一级市教委主管,因此,往往成为市、县两级教委环境教育督导上的盲点。此次调查的目的是通过了解乡村师范学生环境意识的水平状况,了解当前乡村师范环境教育开展的现状,从而发现当前环境教育中存在的问题,为今后环境教育课程改革提供依据。调查内… 相似文献

通过问卷调查法对甘肃省农村居民的环境知识、环境认知、环境保护参与意愿与行为进行了调查与分析。结果表明,甘肃农村居民总体环境知识欠缺,环境意识薄弱;农村居民环境保护的支付意愿受支付额度的影响,环境行为尚有较大的改善空间;较低的文化素质是引起农村环境问题的主要原因之一。甘肃省新农村建设环境保护应做好以下工作:加大教育力度,提高农村居民的整体素质;加大资金投入,加强环境基础设施建设;改变不合理的生产生活方式,加强各方面的监督和管理。 相似文献

It is generally believed that forest cover in North Korea has undergone a substantial decrease since 1980, while in South Korea, forest cover has remained relatively static during that same period of time. The United Nations Food and Agriculture Organization (FAO) Forest Resources Assessments—based on the reported forest inventories from North and South Korea—suggest a major forest cover decrease in North Korea, but only a slight decrease in South Korea during the last 30 years. In this study, we seek to check and validate those assessments by comparing them to independently derived forest cover maps compiled for three time intervals between 1990 and 2010, as well as to provide a spatially explicit view of forest cover change in the Korean Peninsula since the 1990s. We extracted tree cover data for the Korean Peninsula from existing global datasets derived from satellite imagery. Our estimates, while qualitatively supporting the FAO results, show that North Korea has lost a large number of densely forested areas, and thus in this sense has suffered heavier forest loss than the FAO assessment suggests. Given the limited time interval studied in our assessment, the overall forest loss from North Korea during the whole span of time since 1980 may have been even heavier than in our estimate. For South Korea, our results indicate that the forest cover has remained relatively stable at the national level, but that important variability in forest cover evolution exists at the regional level: While the northern and western provinces show an overall decrease in forested areas, large areas in the southeastern part of the country have increased their forest cover. 相似文献

Environmental dredging is a primary remedial option for removal of the contaminated material from aquatic environment. Of
primary concern in environmental dredging is the effectiveness of the intended sediment removal. A 5-year field monitoring
study was conducted to assess the effectiveness of the environmental dredging in South Lake, China. The concentrations of
total nitrogen (TN), total phosphors, and heavy metals (Zn, Pb, Cd, Cu, Cr, Ni, Hg, and As) before and after dredging in sediment
were determined and compared. Multiple ecological risk indices were employed to assess the contamination of heavy metals before
and after dredging. Our results showed that the total phosphorus levels reduced 42% after dredging. Similar changes for Hg,
Zn, As Pb, Cd, Cu, Cr, and Ni were observed, with reduction percentages of 97.0, 93.1, 82.6, 63.9, 52.7, 50.1, 32.0, and 23.6,
respectively, and the quality of sediment improved based on the criterion of Sediment Quality Guidelines by USEPA and contamination
degree values (Cd) decreased significantly (paired t-test, p < 0.05). Unexpectedly, the TN increased 49% after dredging compared to before dredging. Findings from the study demonstrated
that the environmental dredging was an effective mechanism for removal of total phosphorus and heavy metals from South Lake.
Nevertheless, the dredging was ineffective to remove total nitrogen from sediment. We conclude that the reason for the observed
increase in TN after dredging was likely ammonia release from the sediment impairing the dredging effectiveness. 相似文献

西部大开发带来了经济的快速发展,同时也出现了日益严重的环境问题,如长期的“滥砍滥伐”、“滥采乱挖”、“非法盗猎”、“非法开采”、“淘金”等,造成西部地区水土流失严重,土地荒漠化、盐碱化加快、水资源短缺、森林面积锐减等。因此,环境保护已成为西部开发过程中面临的一项迫切任务,其本身作为一项系统工程,需要全社会的共同参与。为了了解西部地区中小学生的环境意识现状,本课题组于2002年6月对西部地区(陕西、甘肃、青海)的中小学生环境意识进行了问卷调查。本文以这次问卷调查的数据为依据,得到西部中小学生环境意识状况,并将其与… 相似文献
