创绿色环保生态矿山走精品循环发展之路——湖州鹿山坞矿业有限公司创建绿色矿山

鹿山坞矿业有限公司的前身是鹿山坞石料厂,始建于1994年。2D02年因杭宁高速公路湖州段建设,根据市政府整体规划要求,并经有关主管部门同意,整体搬迁至妙西镇西园坞内。作为省、市首批省级绿色矿山创建试点单位,鹿山坞矿业有限公司在发展过程中,认真贯彻落实党的十七大精神,按照"建设资源节约型、环境友好型社会"和省委省政府建设生态省要求,积极开展创建绿色矿山活动,合理利用矿产资     

Green Tourism in Mountain Regions - Reducing Vulnerability and Promoting People and Place Centric Development in the Himalayas

In recent years, mountain regions are attracting great attention to Indian tourists in general and foreign tourists in particular. The potential mountain resources for promoting green tourism are enormous in the form of natural and cultural heritage such as biosphere reserves, flora and fauna, lakes and rivers and traditional rural resources. In order to utilise tourism industry market, uncontrolled numbers of tourists and related haphazard infrastructural facilities in the vulnerable mountain regions pose serious environmental implications. The ecological pressures are threatening land, water and wild life resources through direct and indirect environmental impacts together with generation of solid and liquid wastes, so green tourism is emerging as an important task in order to develop new relationship between communities, government agencies and private sectors. The strategy focuses on ecological understanding, environmental protection and ecodevelopment. The major attributes of the green tourism include environmental conservation and education and distribution of income to local people based on strong partnership. Various knowledge systems go a long way for achieving the goals of the green tourism, which creates awareness about the value of environmental resources. Mountains have ecological, recreational, educational and scientific values, which need to be utilised in sustainable way. Various tourist activities andfacilities need to be diversified in order to achieve multiple benefits including scientific field excursion, recreation in natural and cultural areas, community festivals and sport tourisms. Green tourism considers tourism development as an integral part of a national and regional development. The paper discusses the social, economic and environmental dimensions of the green tourism with particular reference to village tourism development programme taking empirical evidences from the Himalaya. Such programme also minimises biophysical and human vulnerability and risks in mountain regions. The environmental consciousness campaign and introduction of code through multi- purpose Tourist Resource Centres are gaining currency in above context.     

小分子伯胺催化异噁唑有氧还原开环反应(英文)

有机催化是催化领域的前沿.在水介质中,以水合肼作为还原剂研究了小分子有机胺催化3-甲基蒽醌-[1,2-c]-异噁唑有氧还原开环反应高效合成1-氨基-2-乙酰基蒽醌,详细考察了不同种类有机胺对异噁唑有氧还原开环反应的催化性能,发现小分子有机伯胺具有很好的还原开环催化性能.在1倍水合肼存在下室温反应3 h,3-甲基蒽醌-[1,2-c]-异噁唑转化率和目标产物1-氨基-2-乙酰基蒽醌选择性均可达到97.2%.产物的分子结构经氢核磁谱和质谱得以确证.此外,提出了小分子有机伯胺催化3-甲基蒽醌-[1,2-c]-异噁唑有氧还原开环反应合成1-氨基-2-乙酰基蒽醌的可能反应机理.     

大型多管水母的绿色荧光蛋白

采用PCR扩增和southern杂交筛选相结合的方法,从厦门水域的大型多管水母中分离到了新的绿色荧光蛋白基因gfpxm,并在大肠杆菌中进行了表达.gfpxmDNA序列编码区长为1042bp,包含3个外显子和两个内含子,cDNA编码区全长为717bp.gfpxmcDNA与已知野生型Aeqgfp 10cDNA长度一致,核苷酸同源性为81.9%,推导的氨基酸序列全长为238个氨基酸,与AeqGFP10的氨基酸同源性为83.6%.将gfpxm克隆至pTO-T7表达载体,GFPxm在大肠杆菌BL21中的表达量达菌体总蛋白的50%左右.荧光性质和强度分析结果表明,GFPxm蛋白的激发峰为476nm,发射峰为496nm,荧光量子产率为1. GFPxm蛋白的荧光很稳定,对热、碱性、变性剂和盐等有较强抗性.     

开发利用清洁能源建设绿色环保内蒙古

现代化社会离不开能源,但是人类大量使用燃烧煤炭、石油和天然气所造成的空气污染,使气温升高,气候变化,已经引起了国际社会的广泛关注,大多数国家签署了《京都议定书》,做出了节能减排的承诺。我国最近也出台了《中国应对气候变化国家方案》,大力提倡开发利用风能、太阳能。风     

加强湿地保护 建设绿色家园

坚持科学发展观,努力实现经济社会快速全面、健康、协调、可持续发展,是新时期摆在全党和全国人民面前的共同历史任务。维护生态平衡,实现人与自然和谐,是经济社会发展的基础和前提,也是人类生存与发展的共同要求。湿地作为全球三大生态系统之一,具有食压力增大,于是大面积的排水造田,把湿地变为耕地,无序利用湿地资源,使我国沼泽湿地最集中分布的三江平原,湿地面积减少到现在的113万公顷,而耕地面积则由原来的3%上升到32%。湿地大面积减少和破坏,导致了三江平原地区生态环境恶化。再如,曾是水浪滔滔的黑河,由于水资源的过度利用,致使黑河断…
