旅游地的类生命特征研究

把旅游地视为一个特殊生命体和特殊的生态系统．旅游地与生物体存在非常类似的机理。具有旅游地生命周期、旅游地生态系统、旅游地之间存在诸如共生、竞争、寄生、捕食生态空间关系等明显的类生命特征。研究旅游地的类生命特征．为运用生态学理论研究旅游发展问题提供了可靠依据和切实可行性，为更好地解释和透视旅游发展问题实质提供了崭新的途径与思路，生态学理论在旅游中的应用和解决旅游问题具有现实的可能性和潜在的应用价值，在丰富旅游学与生态学理论的同时，指导并促进旅游业的可持续发展。     

生态型港口综合评价指标体系初探

基于上海市建设生态型城市的长期目标，将港口作为城市生态系统中重要的子系统，对如何建设生态型港口提出了综合评价指标体系。通过筛选得到45项单因素指标，针对不同类型的港区有所分异，整个评价体系分为5个准则层（生态环境、经济效率、污染控制、环境管理、社会评价）和10个因素层（大气/声环境、生物资源、基底质量、经济发展、生产效率、循环经济、污染排放、清洁生产、环保投入、社会参与），并采用AHP（层次分析）法确定了各层次的权重分配。进而根据2005年上海港年均生产状况和2006年上半年的港区环境－资源调查，尝试对上海港7种主要类型（集装箱、件杂货/成品、多用途、干散、粮食港区、液散、客运）的15个港区进行了现状评估。然而，生态港评价系统的指标选取、权重制定、评估级别等实践与完善仍需要多学科和政府职能部门的参与。最后，项目还提出了水生态健康、航道淤积、生态风险、水陆景观等非定量生态港评价因子。     

On Index System and Quantitative Assessment of Eco-cities： A Case Study on Urban Agglomeration of the Yangtze Delta

Urban agglomeration of the Yangtze Delta （UAYD）, one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modem cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the construction of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.     

The use of ecological scales for indication of the current state of forest communities

A method for estimating the current state of plant communities based on the ecological amplitudes of constituent species is proposed. An original program, Fitoindikatsiya, has been developed to compute the indices of disturbance and homogeneity of plant communities from species ecological scale values. The current state of pine forests in the part of Novosibirsk oblast east of the Ob River has been analyzed; slightly, moderately, and severely disturbed zones have been distinguished.     

试论生态文明建设中的环境保护

随着经济的发展，人们越来越清醒地认识到，以污染环境和破坏生态来换取一时经济繁荣的危害日益突出。正是这种清醒，推动人类文明进行着一场深刻的反思和变革，把追求人与自然的和谐相处，推上当今社会发展主旋律的位置，它预示着人类进入一个生态文明的新时代。生态文明是协调发展物质文明的保障者，是与时俱进的精神文明的塑造者，是日益完善的政治文明的体现者。因此，建设生态文明既是实现全面建设小康社会奋斗目标的内在需要，又是深入贯彻落实科学发展观的重要内容；建设生态文明，必须强化政策支撑，增加生态文明建设的内生动力；必须强化执法监督，增加生态文明建设的环保执行力；必须强化生态补偿能力，构建最具活力的绿色发展模式。     

搞好生态建设,转移农村剩余劳动力

大量闲置劳动力会造成巨大生态压力,加剧生态退化,但只要转移消化得当,便能化为强大的力量和优势。本文从区域→行业→企业→家庭→生态建设联合体五个层次和角度,对各种有效的和有可能的转移消化闲置劳动力生态建设途径进行了探索。     

Sustainability: a Dissent

Abstract:  Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchot-era conservation (and thus ignores the many lessons learned since then); it need not be linked to land, to the land's functioning, or to any ecological science; it need not include a moral component; it is consistent with the view of humans as all-powerful manipulators of the planet; and, in general, it is such a malleable term that its popularity provides only a facade of consensus. When sustainability is defined broadly to include the full range of economic and social aspirations, it poses the particular risk that ecological and biodiversity concerns will be cast aside in favor of more pressing human wants. Given these many defects, the conservation movement should discard the term in favor of a more alluring goal, attentive to nature and its ecological functioning. A sound goal would incorporate and distill the considerable ecological and moral wisdom accumulated since Pinchot's day while giving conservationists the rhetorical tools needed to defend the land against competing pressures. In our view, conservation would be well served by an updated variant of "land health," Aldo Leopold's ecologically grounded goal from the 1940s. Land health as an independent understanding should set the essential terms of how we live and enjoy the earth, providing the framework within which we pursue our many social and economic aims.     

构建人类命运共同体、应对气候变化与生态文明建设

全球气候变化给人类社会文明带来严峻挑战,需要人类社会采取共同措施和行动积极应对。应对全球气候变化是当今世界最能体现人类共同命运的领域,深度参与并积极推动全球气候治理体系改革和建设是中国推动构建人类命运共同体的重要实践,也是生态文明理论和实践的重要方面。应对气候变化是我国生态文明建设的重要内容和内在要求;以共同价值理念构建人类命运共同体,凝聚各国力量携手合作应对全球气候变化,是全球生态文明建设和构建人类命运共同体的具体实践,也为应对全球气候变化提供了良好载体和国际平台。文章通过分析可知,应对气候变化、生态文明建设与构建人类命运共同体三者之间,呈现出相互促进、和谐共生的"三位一体"特征;人与自然共生的生命共同体是前提条件,人类的任何实践活动都要以自然生态系统为基础和前提;人类命运共同体在整合各国力量方面,为生态文明建设提供了社会基础;生态文明包容各国文明,凝聚价值共识,成为生命共同体和人类命运共同体的价值导向。中国倡导人类命运共同体理念,是全球生态文明和人类命运共同体的积极倡导者、推动者和践行者,既为应对全球气候变化提供了价值基础,也提供了强有力的实践支撑;应对气候变化是全球生态文明建设和人类命运共同体构建的生动实践。因此,加强生态文明建设和构建人类命运共同体,为全球应对气候变化提供了理论基础和国际平台,也将为全球可持续发展贡献中国智慧和中国案例。     

省以下生态转移支付制度环境保护激励效应

现有文献认为生态转移支付具有基本公共服务均等化与提升地方生态环境质量双目标,而目标的多样性会影响地方财政转移支付资金效果及目标的实现。文章基于环保支出和农林水支出的中介与调节效应,对生态转移支付的生态环境目标进行了理论分析,利用2010—2018年甘肃、贵州、湖北及河南四省的199个县的面板数据进行实证检验。实证研究表明:在样本期内,生态转移支付促进了地方生态环境质量的提升,中介效应和调节效应模型的结果表明,中国地方生态转移支付资金对辖区环境保护效果中,环境保护支出起到部分中介效应,农林水支出不仅调节了生态转移支付的地方环境保护支出效果,而且调节了环境保护支出对地方环境质量的影响。因此,由于地方政府具有环境治理信息优势,省以下制度目标更能体现辖区生态需求,省对县生态转移支付制度会有效促进地方生态环境质量的改善,环保激励效应较为明显。同时,县级地方政府应该逐步摆脱"先污染后治理"的路径依赖,逐步转向经济与环境"双目标协同发展"模式。为了协同生态转移支付的双目标,"自下而上参与式决策"可以作为环境治理的有益补充,通过地方政府多元化实践改善环境质量。     

沱江沉积物中有机氯农药分布特征及其与藻类有机质的关系和生态风险评估

使用气相色谱-质谱联用仪分析了长江支流沱江流域48个表层沉积物中有机氯农药（organochlorine pesticides,OCPs）的残留水平,探讨了其分布和组成特征及其与总有机碳（total organic carbon,TOC）、藻类有机质之间的关系,以及评估其生态风险.结果表明沱江流域表层沉积物中OCPs的总含量为3.17~127 ng·g^-1,其中六六六（hexachlorocyclohexane,HCHs）类农药的含量为2.83~86.0 ng·g^-1,滴滴涕（dichlorodiphenyltrichloroethane,DDTs）类农药的含量为0.340~40.9 ng·g^-1.OCPs空间分布特点为：上游 < 中游 < 下游 < 支流.HCHs和DDTs的组成成分分析表明,沱江流域存在林丹输入的现象,主要来自于历史残留,这与绝大多数流域的DDTs的输入状况相似.OCPs含量与TOC、藻类有机质含量之间存在着极显著的正相关性关系,表明藻类有机质在TOC对沉积物中的OCPs分配中起更为重要的作用.生态风险评估表明,沱江流域表层沉积物的有机氯农药存在较大的生态风险,可能对河流的底栖生物及生态环境造成明显的影响.
