从自已做起，从今天做起

2007中国公众环保民生指数近日在北京正式发布。调查显示,公众的环境意识总体得分为42．1分,环保行为得分为36．6分,环保满意度得分为44．7分,3项指标均不及格。这无疑为中国公众的环保意识与行为敲响了警钟。     

我国矿山地质环境恢复补偿制度建立与完善探讨

当前,我国经济建设对矿产资源勘查开发需求越来越强劲,因开采矿产资源所造成的越来越突出的矿山地质环境问题不仅威胁到人民生命安全,而且严重地制约了国民经济的发展。因此,迫切需要加强矿山地质环境保护和恢复治理,这也与国家环境政策的要求相适应,而建立矿山地质环境恢复补偿制度（或机制）则是一项十分有效的制度保障。

从孢粉分析试论北京地区两泥炭矿的时代和形成环境

本文应用孢粉分析,对北京地区两个泥炭矿的时代和形成环境进行了探讨。指出:泥炭成矿时期的气候是温暖而湿润的,气温较现今高。植物生长茂盛,属针阔叶林植被。泥炭是在植物残体的不断积累、分解和腐烂,长期保存在水体及后期泥砂覆盖的还原环境之下,上覆压力不断增加,沉积物的堆积速度与湖沼下降的速度长期保持相对平衡等条件下形成的。泥炭成矿的地质时代主要在中全新世     

殚精竭虑谋发展

春花秋月又一年，晨光暮色不释卷。与时俱进开新篇，殚精竭虑谋发展。刚刚过去的一年，是“十五”计划的总结之年。根据2005年11月30日最新发布的《中国学术期刊综合引证年度报告（2005）》（统计源刊5941种），《云南地理环境研究》影响因子为0．573，在云南各个高等院校所办的全部期刊中名列第一，在云南所有期刊中名列前茅，在全国地理类期刊中名列13，远远超前于不少“核心期刊”，为“十五”画上了一个圆满的句号。     

青藏高原腹地湖泊沉积对第四纪晚期古季风变化的响应

通过对青藏高原腹地的综合科学考察和对中心钻孔岩芯剖面的最新研究,用层序地层学与年代地层学和气候地层学相结合的方法,分辨出可可西里地区湖泊沉积记录(孔深7.25 m)的第四纪晚期距今3万余年以来的古气候变化,沉积物磁化率等因子综合表征的高原古季风变化是波动发展的,发生在仙女木期地质环境事件中的季风活动具有强烈暴发的特点,是高原季风发展中的突变事件,而且地表热点效应对其起到了激发作用。综合分析的研究成果表明,它的变化频谱与激变因子及其运行机制是伴随着青藏高原地质效应的演变而发展的,为研究第四纪冰消期以来的气候变化提供了新的信息。     

Changes in manganese and lead in the environment and young children associated with the introduction of MMT in gasoline

This is a 4-year longitudinal study to evaluate changes to the environment and exposure of young children associated with the introduction of methylcyclopentadienyl manganese tricarbonyl （MMT） into Australia in 2000. The cohort includes 57 females and 56 males; age range of 0.29 to 3.9 years. Samples are collected every 6 months from children in residences located at varying distances from major traffic thoroughfares in Sydney. Environmental samples： air, house and day care dustfall, soil, dust sweepings and gasoline. Samples from children： blood, urine, handwipes prior to and after playing outdoors, and a 6-day duplicate diet. All samples are analyzed for a suite of 20 elements using ICP-MS. Results are presented for the first three 6-month sampling periods for Pb and Mn. For dustfall accumulation, there was no significant change over the 3 sampling periods （time） for Pb or Mn, and a positive relationship between ‘traffic exposure＇ （traffic volume and proximity to the road） and Pb but not Mn. For handwipes, Pb and Mn in wipes taken from children after playing outdoors were usually significantly greater than for wipes taken prior to playing. There was no significant association between Pb or Mn in handwipes with traffic exposure. Dustfall accumulation was a significant predictor for Pb in the handwipes, and dust sweepings were a significant predictor of Mn in handwipes.     

Environmental geohydrochemistry and health of the high altitude population in Ladakh

Background： Radiographic signs of Pneumoconiosis found in farming Ladakhi despite absences of mines and industries were believed to be due to exposure to frequent dust storms and domestic fire pollutions. Seasonal Koilonychia （spoon nail） occurring predominantly in farming women in absences of iron deficiency anaemia was thought to arise from exposure to water made alkaline by weathering of hornblende minerals. The relation of these health conditions to environmental geohydrochemistry is postulated as the source of irrigation water in the affected population originates from glaciers in trans-Himalaya range of sedimentary geology and steep landscape favouring flushing of silica/silicate containing silts. Methods and results： Survey in two central Ladakh villages revealed radiographic evidence of silicosis in all middle aged women and half in middle aged men. In a large-scale study of 3105 subjects aged over 30 years from three villages; 101 （22.5%） of the 449 radiographed showed signs of pneumoconiosis （ILO 1980 criteria） including eggshell calcification of hilar gland and progressive massive fibrosis. Indoor dust analyzed using Philips 400T electron microscope with energy dispersive analysis system attached showed SiO2 levels upto 53.27% with particle size of 0.5 to 5.0 microns and the concentration during cooking period in the worst affected area was 7.495 mg/m^3. Microscopy and histopathology from the subject was characteristic of pneumoconiosis. Analysis of the inorganic dust in the lung showed 40.2% muscovite, 37.3% quartz with the extracted dust wt 147.9 mg/gm of dry tissue. Prevalence of chronic cough with chronic phlegm and percentage of villagers with FEV1/FVC ratio of less than 65% rose with age. Of 70 subjects studied 19 women and 2 men had Koilonychia with incidence being highest in summer. Absence of seasonal Koilonychia in villages fed by water derived from northern mountain range glaciers with mainly igneous geology supports our hypothesis.     

温地公园概览

湿地公园（Wetland Park）的概念类似于小型保护区．但又不同于自然保护区和一般意义公园的概念。根据国内外目前湿地保护和管理的趋势．兼有物种及其栖息地保护．生态旅游和生态环境教育功能的湿地景观区域都可以称之为“湿地公园”，
