【目的】近几十年,中国工业和城市化进程飞速发展,但也带来一系列频发的污染事件,如石油泄漏、重金属污染等。在这样的背景下,对污染全过程的精准评估和污染场地的管控是实现污染场地治理和修复的重要环节。【方法】本文以石油泄漏污染为例,采用对象化的视角和系统性的分析方法,描述污染物从源到汇的完整过程,表达污染物在迁移过程中的环境行为。首先,将污染场地及关联的实体抽象表达为时空对象,并说明其组织结构;其次,围绕污染物的浓度表达,描述各时空对象与之相关的属性特征;然后,从时间、空间、属性3个方面描述各时空对象之间的关联关系;最后,描述各时空对象相互之间的动态影响。【结果】①以2014年某地的一起原油泄漏真实事件为例,以XML结构的表达方式,构建了污染场地的对象化表达模型;②构建了污染场地对象可视化表达方法,用于展示各时空对象的关联关系和属性特征;③尝试应用表达模型开展对污染物浓度的归因分析,快速获取暴露评估指标的相关计算参数,从而更便捷地进行健康风险评价。【结论】本文通过对象化表达方法构建的模型能够有效描述污染场地并对其建模,有助于对污染从源到汇的全过程分析和评估,为实现污染场地的管控和修复提供重要支持。此外,本文提出的对象化表达方法在解决复杂问题时具有实践可借鉴性。通过将研究对象视为一个对象,从组成结构、属性特征、相互关系以及行为动态等多个方面进行分析和表达,可以更好地理解研究对象内部关系和相互影响,为相关问题的分析和评估提供清晰的视角。

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。

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.
