国内外旅游系统模型研究综述

从系统论角度来考虑。人类的旅游活动是一个系统。旅游系统是备种旅游事象的集合体。是通过旅游者的旅游活动使备组成要素相互联系、相互作用构成的一个有机整体．它具有实现旅游价值的整体功能。在分析和阐释旅游系统特征的基础上，以时间为序列对国内外学者提出的旅游系统模型进行了介绍评述和总结．指出系统论的观点不仅为旅游资源的开发提供了认识论基础；同时又为旅游规划和开发提供了方法论基础，并提出，对具有环境观和复杂性特点的旅游地理系统的研究将成为未来旅游科学的重要研究方向。旅游系统模型的建立将为旅游（业）的研究提供现实的理论基础。     

Scientists as Stakeholders in Conservation of Hydrothermal Vents

Abstract: Hydrothermal vents are deep‐sea ecosystems that are almost exclusively known and explored by scientists rather than the general public. Continuing scientific discoveries arising from study of hydrothermal vents are concommitant with the increased number of scientific cruises visiting and sampling vent ecosystems. Through a bibliometric analysis, we assessed the scientific value of hydrothermal vents relative to two of the most well‐studied marine ecosystems, coral reefs and seagrass beds. Scientific literature on hydrothermal vents is abundant, of high impact, international, and interdisciplinary and is comparable in these regards with literature on coral reefs and seagrass beds. Scientists may affect hydrothermal vents because their activities are intense and spatially and temporally concentrated in these small systems. The potential for undesirable effects from scientific enterprise motivated the creation of a code of conduct for environmentally and scientifically benign use of hydrothermal vents for research. We surveyed scientists worldwide engaged in deep‐sea research and found that scientists were aware of the code of conduct and thought it was relevant to conservation, but they did not feel informed or confident about the respect other researchers have for the code. Although this code may serve as a reminder of scientists’ environmental responsibilities, conservation of particular vents (e.g., closures to human activity, specific human management) may effectively ensure sustainable use of vent ecosystems for all stakeholders.     

科学发展观的内涵与特征

概述了科学发展观的内涵；认为它是以人为本，以全面、协调和可持续为根本特征；它强调经济发展、社会发展和人的全面发展、人口、资源、环境等各方面的和谐与统一。这种新的理念应该转化成为政府的具体行动。

水环境优先与兼顾水资源——关于水发展秩序的一个新型战略发展框架

水既是母体性的重要战略环境．还是父体性的重要战略资源。其双重特征和叠加功用决定了水对人类的生存发展具有至高无上的战略性。我们有充分的论据认为。在水的双重特性中水环境比水资源更加重要．在水发展序列中水环境发展重于水资源发展。中国决策层已经在水资源方面提出了建构“节水型”社会的发展要求，但还没有从水环境的视角确立建构“洁水型”社会的发展战略。21世纪的现代水科学发展观要求我们必须在洁水优先和兼顾节水的发展理念引领下。建构洁水与节水相结合的杜会发展模式。寻求21世纪中国新型的水利科学发展道路。只有如此．才能真正建构起能够切实保障中国水利安全的战略发展框架。     

Defending the scientific integrity of conservation‐policy processes

Government agencies faced with politically controversial decisions often discount or ignore scientific information, whether from agency staff or nongovernmental scientists. Recent developments in scientific integrity (the ability to perform, use, communicate, and publish science free from censorship or political interference) in Canada, Australia, and the United States demonstrate a similar trajectory. A perceived increase in scientific‐integrity abuses provokes concerted pressure by the scientific community, leading to efforts to improve scientific‐integrity protections under a new administration. However, protections are often inconsistently applied and are at risk of reversal under administrations publicly hostile to evidence‐based policy. We compared recent challenges to scientific integrity to determine what aspects of scientific input into conservation policy are most at risk of political distortion and what can be done to strengthen safeguards against such abuses. To ensure the integrity of outbound communications from government scientists to the public, we suggest governments strengthen scientific integrity policies, include scientists’ right to speak freely in collective‐bargaining agreements, guarantee public access to scientific information, and strengthen agency culture supporting scientific integrity. To ensure the transparency and integrity with which information from nongovernmental scientists (e.g., submitted comments or formal policy reviews) informs the policy process, we suggest governments broaden the scope of independent reviews, ensure greater diversity of expert input and transparency regarding conflicts of interest, require a substantive response to input from agencies, and engage proactively with scientific societies. For their part, scientists and scientific societies have a responsibility to engage with the public to affirm that science is a crucial resource for developing evidence‐based policy and regulations in the public interest.     

Bibliometric analysis of ecosystem monitoring-related research in Africa: implications for ecological stewardship and scientific collaboration

Regional ecosystem monitoring is a central form of knowledge sharing and collaboration amongst scientists and decision makers on environmental health, land use change, and science-policy development. Despite the proliferation of such research networks on long-term monitoring on many continents, little has been achieved in Africa. This study aims to assess and examine the spatiotemporal trend and categorical patterns in ecosystem monitoring-related research in Africa for the benefits of conserving biodiversity and sustaining natural resource sectors for well-being and livelihood security, environmental planning, and ecological stewardship. A systematic review was conducted using bibliometric tools. Based on a set of search terms and peer-reviewed publications retrieved from various ecosystem monitoring networks and journal databases, further analysis was conducted using social network approaches, mapping tools, and content analysis. About 1442 scientific publications on ecosystem monitoring and related research were documented from 1987 to 2014 mostly published in English. The number of publication increased progressively since 1992 after the Convention on Biodiversity was signed and this trend peaked till 2008. South African Journal of Science was the most leading journal and Nature the most cited. Internationally coauthored and collaborative articles represented majority of the findings with the United Kingdom at the central position in the research network due to colonial relationships. Regional collaboration amongst countries is limited owing to language barriers and other institutional constraints such as funding and short-term projects. These findings have implication for prioritizing national and regional policies toward biodiversity science and its contribution to human well-being, food security, and global change responses.

底栖动物在水质评价中应用的中文文献统计和分析研究

底栖动物长期生活在水体底部,水质的变化会直接影响到它们的生长和繁殖,因此底栖动物可以准确的反映水体的质量.利用底栖动物对水质进行生物评价,在国内已较多采用,并取得了一定的成果.在收集、整理了126篇底栖动物在水质评价中的应用的相关中文文献的基础上,统计出了这些文献的年度发表量及在各期刊的分布情况,其中核心期刊占有较大的比例.此外,还统计了文献的研究机构,主要是以高校为主体,以及文献所用的评价水质的方法,共计14种.
