苏北地区农业环境问题及管理方案的探讨

配合江苏省“碧海计划”和盐城市海洋经济绿色农业的发展，探讨了现阶段农业环境污染控制的直接政策管理、经济手段和人工生态工程处理三种方案，其中政策管理，如减少化肥农药的施用规定能减少污染，直接经济投入少，但是执行管理成本高，且政策见效慢；经济手段能减少污染，但环境目标达标不确定，且需要完善的市场环境，目前来说，本地区市场机制不完善，会出现“市场失灵”现象；人工湿地生态工程，前期投入大，但管理成本低，环境目标确定，但不能快速削减污染负荷。三种方案各有所长，在实际操作中，应针对不同区域的农业产业状况、方案时间迟度组合使用。     

室内PM2.5浓度控制模拟分析

利用质量平衡方程建立了一次回风定风量系统室内PM2.5浓度模型,并对新风PM2.5浓度、新风量、室内污染源、过滤器效率、过滤器安装位置等因素对室内PM2.5浓度的影响进行了模拟分析。模拟结果表明：新风PM2.5浓度和室内污染源强度的变化对室内PM2.5浓度均有较大影响;新风量越大,室内PM2.5浓度受新风PM2.5浓度变化的影响越大;将过滤器分别安装在送风段、新风段和回风段,新风比为0.1时,过滤器安装在送风段效果最好,安装在新风段最差,新风比为0.8时,过滤器安装在送风段效果最好,安装在回风段最差;过滤器安装在送风段时,过滤器效率越高,室内PM2.5浓度越低,波动越小。

Enhanced science–stakeholder communication to improve ecosystem model performances for climate change impact assessments

In recent years, climate impact assessments of relevance to the agricultural and forestry sectors have received considerable attention. Current ecosystem models commonly capture the effect of a warmer climate on biomass production, but they rarely sufficiently capture potential losses caused by pests, pathogens and extreme weather events. In addition, alternative management regimes may not be integrated in the models. A way to improve the quality of climate impact assessments is to increase the science–stakeholder collaboration, and in a two-way dialog link empirical experience and impact modelling with policy and strategies for sustainable management. In this paper we give a brief overview of different ecosystem modelling methods, discuss how to include ecological and management aspects, and highlight the importance of science–stakeholder communication. By this, we hope to stimulate a discussion among the science–stakeholder communities on how to quantify the potential for climate change adaptation by improving the realism in the models.     

VOCs源强不确定性对臭氧生成及污染防治影响的模拟分析

Integrated strategies to reduce vulnerability and advance adaptation,mitigation, and sustainable development

Determinants of adaptive and mitigative capacities (e.g., availability of technological options, and access to economic resources, social capital and human capital) largely overlap. Several factors underlying or related to these determinants are themselves indicators of sustainable development (e.g., per capita income; and various public health, education and research indices). Moreover, climate change could exacerbate existing climate-sensitive hurdles to sustainable development (e.g., hunger, malaria, water shortage, coastal flooding and threats to biodiversity) faced specifically by many developing countries. Based on these commonalities, the paper identifies integrated approaches to formulating strategies and measures to concurrently advance adaptation, mitigation and sustainable development. These approaches range from broadly moving sustainable development forward (by developing and/or nurturing institutions, policies and infrastructure to stimulate economic development, technological change, human and social capital, and reducing specific barriers to sustainable development) to reducing vulnerabilities to urgent climate-sensitive risks that hinder sustainable development and would worsen with climate change. The resulting sustainable economic development would also help reduce birth rates, which could mitigate climate change and reduce the population exposed to climate change and climate-sensitive risks, thereby reducing impacts, and the demand for adaptation. The paper also offers a portfolio of pro-active strategies and measures consistent with the above approaches, including example measures that would simultaneously reduce pressures on biodiversity, hunger, and carbon sinks. Finally it addresses some common misconceptions that could hamper fuller integration of adaptation and mitigation, including the notions that adaptation may be unsuitable for natural systems, and mitigation should necessarily have primacy over adaptation.

中国冰川旅游资源开发模式与对策研究

中国冰川资源规模巨大,形态各异,在国内旅游市场中具有绝对的垄断性地位。然而,我国冰川旅游发展却较为缓慢,景点稀少,与冰川资源禀赋极不相符,与国外冰川旅游发展差距较大。冰川旅游资源的吸引功能并非由冰川旅游单体决定,往往由冰川及周边景观的组合程度大小决定。鉴于此,中国冰川旅游需要改变以往冰川观光和其他单一景点开发模式,进而向冰川、雪山、森林、草甸、湖泊、峡谷与民族文化组团式开发转变,通过冰川与其他景观的组团式开发模式,扩展其冰川旅游类型与内涵,延伸其高山带山地旅游产业链,提升我国冰川旅游产品品牌价值,以此为我国冰川资源优势转变为经济优势提供理论与实践支持。     

浅谈秦皇岛外语语言软环境的优化策略

秦皇岛作为著名的沿海旅游城市,外语语言环境作为旅游软环境的一个重要因素直接影响着整个旅游产业的综合竞争力。鉴于此,对秦皇岛市外语语言软环境进行调查摸底。调查结果表明,旅游景区标示语及城市公示语的翻译存在不同程度的问题,旅游从业人员总体素质不高,市民的外语能力普遍偏低。以调查结果为依托,从政府导向、行业把关、全民参与三方面提出了优化秦皇岛市旅游业外语语言软环境的建议。

Trends in management plans and guides: 25 years of experience from Southern France

This study analysed 14 management plans and guidelines from a 25-year period to understand trends in conservation planning. A Rosetta Stone Analysis was used for the systematic comparison of plans and guidelines. Management plans incorporated management philosophies, management scenarios, opportunities for infrastructure, and plans for data collection by 2000. As of 2010, they incorporated ecosystem services, stakeholders’ objectives and methods for storing and analysing data. The results demonstrate the complex nature of management plans, with an important workload for site managers. Recommendations for future planning include adjustments in planning timeframes and a better identification of conservation targets from initial stages.
