水生态环境监测是生境保护的前提和基础,针对长江流域水系点多面广、复杂多样、瞬息万变等特点,对监测手段提出了更高的要求。目前,针对大型地表水系的水质监测方式仍以人工取样结合实验室化学分析或现场手持式仪器分析为主,存在方法滞后、手段单一、频次偏低、面源缺失等问题。因此,迫切需要新体制监测技术,突破实时快速、面源定量等现实需求,为长江水系统综合模拟提供可靠数据源。在此背景下,本文提出了一种具有完全自主知识产权的精细光谱探测与计量分析技术,开发了地基、空基等体系技术与装备,在相关项目支持下,开展了体系化技术的示范应用,在长江干流关键断面、三峡示范区和鄱阳湖示范区进行了空—地立体监测,取得了良好效果。监测数据经云平台接入“长江模拟器”,为其综合运行提供了快速实时数据支持,也为未来流域大型水系综合监测提供了新方法和应用典范。

红色旅游政策作为推动红色旅游高质量发展的关键因素,长期以来一直受到政府和学术界的广泛关注,然而,目前鲜有研究对红色旅游政策变迁及其影响机制进行专门探讨。文章基于多源流理论和微观“地方”视角,选取中国3个典型红色旅游地(韶山市、瑞金市和井冈山市),运用定性比较分析方法对思政教育政策、文化产业政策、组织机构变革、重大主题活动、旅游市场舆情、社会公众参与等因素引发红色旅游政策变迁的组态效应进行分析。研究发现:1)红色旅游政策变迁的影响因素不存在单一必要条件,是多因素交互耦合作用的结果;2.红色旅游政策变迁的驱动类型主要包括群情驱动型、政策驱动型、组织驱动型、政策-群情驱动型、政策-组织驱动型、组织-群情驱动型、政策-组织-群情驱动型和弱混合驱动型8类;3)由旅游市场舆情和社会公众参与组成的群情因素是影响红色旅游政策变迁的核心因素。文章在一定程度上厘清了红色旅游政策变迁的影响因素及其作用机制,能够为相关政策的科学制定及有效实施提供理论基础和实践参考。

The classification and assessment of vulnerability of man-land system of oasis city in arid area

Frontiers of Earth Science 2013年第4期7卷 406-416页

Oasis city system is the center of the man-land relationship in arid area and it is the most influential spatial and temporal multiple dynamic system. Oasis city system is not only the largest area where artificial disturbances occur at a regional scale but also the most concentrated area of human activity in arid area. In this study, we developed an applicable and convenient method to assess vulnerability of man-land system of oasis cities with vulnerability indicator system, respectively evaluating the sensitivity, adaptability and vulnerability of the eco- environment system, the economic system and the social system. The results showed that the sensitivity and vulnerability of oasis cities in Xinjiang, china have significant differences while their adaptability does little. In order to find the inherent differences in the vulnerability of oasis cities, triangle methodology has been adopted to divide Xinjiang oasis cities into five types. Some adaptive developing policies specific for individual cities are also proposed based on their vulnerability type and constrain- ing factors.
