福建三明是全国为数不多的百万担优质烟叶产区之一,地处福建西北部,闽江上游,武夷山脉和戴云山脉之间,森林覆盖率达76.8%,素有绿色宝库之美誉,生态条件极其适应优质烟叶生产.目前,三明烟区常年种烟面积40~45万亩,收购烟叶100~120万担.近年来,三明烟区紧

鄂尔多斯盆地长7油层组沉积期是湖盆发育的鼎盛期,不但沉积了大面积分布的优质烃源岩,而且还发育一定规模的储层。对储层所处沉积环境、储层特征、成岩相及生、储、盖组合等综合地质条件进行分析研究,结果表明,长7储层烃源条件优越,有利储集体主要为三角洲前缘的水下分流河道及半深湖-深湖相浊积岩,岩石类型以低成分成熟度的岩屑长石砂岩和长石岩屑砂岩为主,储层物性差,孔隙度平均8.45%,渗透率平均0.12×10-3μm2,属超低孔低渗储层;发育5种成岩相类型。最有利成岩相为胶结作用-微孔粒间孔和溶蚀作用-溶孔微孔成岩相,分布面积有限;储层物性最差的为压实胶结-微孔成岩相,分布面积较广。半深湖-深湖沉积环境导致长7储层横向连通性差,纵向隔夹层多,油气只能通过垂向和短距离的侧向运移,在遇到泥岩遮挡层或致密砂岩遮挡时在相对物性较好的储层中聚集成藏。

9月21日,细雨中的浙江省衢州市衢江区山水朦胧,更显出钱江源头的生态之美.此时的衢州市衢江区会议中心内群贤毕至,为衢州市衢江区的生态优势和绿色发展出谋划策.这就是大型社会公益活动绿色中国行系列活动之一-电视访谈节目8+1对话:秀美衢江,生态家园的直播现场.

作为时代主题之一的生态问题,面临价值多元化的局面,多样化的生态价值观念带有各自的生态立场与诉求,在一定程度上表现出不可通约性和不可兼容性.面对生态价值观念的多元性,自由民主制度的偏好聚合模式存在缺陷,需要寻求另一种以偏好转换为核心的公共协商形式,协商民主在理论讨论和制度设计上有利于保护多元性的价值观念和提升生态敏感性.生态政治与民主政治之间可以相互促进,在宪法权利和公民社会两个领域对民主的绿化,将有效地提升民主制度对合理生态价值观念的关注度,并为与环境决策相关的公共协商创造更有利的条件,从而对环境的改善和民主质量的提升产生双赢的效果.

从生态系统、哲学伦理学、生态环境效应的视角分析了技术创新生态化的三重意蕴,并认为建设生态文明要求实现技术创新的生态化转向,即要把保护生态环境的理念和相关的生态环境指标贯彻或纳入技术创新的全过程.然后,从生态文明的视角,以产品创新过程为例,探讨了从研究开发、产品生产、市场营销到技术扩散的整个技术创新过程的生态化问题.最后,提出了技术创新生态化应遵循的几个原则:低消耗高效益原则、零排放无污染原则、以人为本原则和技术可回收性原则.

"生态学马克思主义"生态危机理论深刻揭示了资本主义制度及生产方式与全球性生态危机的必然性联系,指出生态危机的资本主义制度根源,将解决生态危机与社会主义联系起来,主张建立生态社会主义社会,并就如何实现生态社会主义提出了一系列方案.这对于我们正在进行的社会主义现代化建设具有多方面的重要启示.

一、加强生态环境保护是省委、省政府的重要发展战略党的十七大以来,省委、省政府以落实党中央、国务院加强生态文明建设和温家宝总理关于保护好鄱阳湖"一湖清水"的指示为契机,举全省之力编制和实施《鄱阳湖生态经济区建设规划纲要》,力争探索一条生态与经济融合的发展道路.规划提出实施鄱阳湖水利枢纽、"五河一湖"水污染治理、"一大四小"造林绿化、长江暨鄱阳湖流域水资源保护、城镇生活污水处理、工业园区污水处理、农村清洁等12大生态经济工程.2011年省第十三次党代会进一步提出"建设富裕和谐秀美江西"的奋斗目标,将建设生态文明确立为未来五年发展的主要目标.

说到湿地,您脑海里是不是会浮现这样的画面:芦花飞荡,香蒲拂摇,睡莲、浮萍飘摆于水面之上,在和煦的阳光下,绿色丝绸般的波浪一层层直涌到天边,各色鸟儿在水面肆意嬉戏鸣唱……没错,这就是原始湿地的真实写照.作为地球三大生态系统的湿地拥有孕育多种生命的巨大潜能,因而被誉为"生命的摇篮""物种的基因库".但从20世纪初开始,随

Most seabird species display colonial behavior during the breeding period which implies that food resources around breeding sites can easily go depleted. Seabirds need to both reach profitable areas, which can be located far from the colony, and return to the colony regularly. In this context, flexibility in movement behavior may be crucial for breeding success. During chick-rearing, Procellariformes species can alternate short trips lasting 1-4 days for chick provisioning with longer trips for self-provisioning in what has been called a dual-foraging strategy. We analyzed foraging trips from 136 Scopoli's shearwaters from three Mediterranean colonies tracked with GPS during 6 chick-rearing seasons to assess whether the adoption of a dual fo- raging strategy depends on the quality of habitat surrounding the colony. We found a marked dual-foraging strategy only in birds from the Linosa colony which was the largest colony in terms of breeding pairs and was characterized by having a lower marine habitat quality. Birds from this colony performed foraging trips that extended up to 369 km from the nest and lasted more than 10 days. In general, the decision to perform long lasting trips was triggered by lower values of primary production and higher offspring weight. Contrary to expectation, the decision to feed far from the colony was not related to the parents' weight. At the same time, despite the higher productivity offered by distant areas, the higher proportion of long trips performed by birds breeding in poor areas was not sufficient to maintain the same body mass as the ones breeding in richer areas [Current Zoology 60 (5): 622-630, 2014].
