沙尘环境对直升机的危害及防护对策探讨

我国是沙漠化危害严重的国家。沙尘环境,特别是沙尘暴天气对直升机危害非常大。通过大量的资料分析和国内外直升机在沙漠地区使用保障的实践经验总结,初步论述了沙漠地区的气象特点,以及为提高直升机在沙尘环境中的战备完好性所采取的防护措施。     

基于遥感的海域环境变化监测分析

以杭州湾海域和连云港周边海域为研究对象,基于Landsat-5、Landsat-9的多光谱和热红外数据,对研究区的海域岸线和温度场信息进行提取,分析海域岸线变迁和温度分布变化特征。结果显示,研究区的海域岸线变化均较显著;海域温度在核电站运行前较为均匀,无明显温度分异,核电站运行后,因温排水排放,核电站周边海域温度出现明显分异;Landsat-9热红外数据温度反演结果可靠,可用于监测温排水对海域环境的影响。     

农业生态环境治理与可持续发展

我国是一个农业大国 ,由于长期的农业生产中忽视了对农业生态环境的保护 ,近年来 ,农业环境和农产品污染问题日趋严重 ,耕地环境质量不断下降 ,土地沙化形势十分严峻。农产品有毒有害物质残留问题突出 ,已成为制约农业和农村经济发展的重要因素。针对农业生态环境污染日益加剧的严峻形势 ,必须加大农业生态环境建设和保护力度 ,采取合理措施 ,在农业生产过程中降低化肥和农药的使用和环境造成的污染 ,推广清洁生产应当成为推动新世纪农业进步的发展新模式。与世界其它国家一样 ,合理利用资源和保护生态环境是农业可持续发展的基础。必须实施可持续发展战略 ,大力推广生态农业和生态农村建设 ,调整优化农业生产结构 ,从粗放型向集约型转变 ,以确保 2 1世纪我国农业的可持续发展。     

Simulative governance: on the collaborative narrative of civil society participation in the CDM stakeholder framework

The Kyoto Protocol’s Clean Development Mechanism (CDM) is often cited as an exemplar of new, hybrid forms of global environmental governance operating at the public–private interface. Practically, enacting this arrangement involves a wide range of non-state actors. This broad involvement is here assumed to mark a shift towards more polycentric and networked modes of governance in which agents collaborate as ‘stakeholders’ in the process of consensual rule-setting and implementation. Using post-political critique, the depoliticising effects of the stakeholder framework on civil society actors are interrogated, using formal and informal participation opportunities to raise concerns regarding specific CDM projects. The analysis suggests that the CDM’s collaborative narrative of stakeholding structurally fails to stimulate public (re)engagement and is, instead, a prime example of simulative governance that struggles to achieve the simultaneity of two incompatibilities: the participatory revolution and the post-political turn.     

Radioecology, radiobiology, and radiological protection: frameworks and fractures

A framework for the protection of the general public has been in existence for a very long time, although steps have recently been made by the ICRP to ensure that it is more fully comprehensive with regard to all actual and potential exposure situations. Protection of the environment, however, has only recently begun to be addressed in a structured manner, and is still an evolving subject. Nevertheless, it needs to be centred around some form of parallel framework to that which has evolved for the protection of human beings, although clearly on a different scale. It also needs to be embedded within the basic science of radiobiology, and form a central part of radioecology.     

我国城乡环保一体化的制度建构:理念、原则与路径

近年来,我国"城市环境趋向好转,农村环境不断恶化"这种城乡环境二元趋势的凸现,提出了城乡环保一体化的客观要求."城市中心主义"环境法制以及我国农民实质自由的严重匮乏是我国产生城乡环境二元趋势的根本原因.一些地方所采取的仅仅局限于环保领域的城乡环保一体化措施,并不能从根本上扭转城乡环境二元趋势.城乡环保一体化实践需要以更为全面的制度建构为基础.城乡环保一体化的制度建构应树立理性、人本、自由等基本理念,应坚持整体推进、科学建构、多元参与等基本原则.城乡环保一体化的制度建构路径,首先是消除对农民的各种制度性歧视,实现城乡居民的权利平等;其次,在推动地方民主与法治建设,推进司法体制改革、建立司法审查制度的基础上,健全与完善农民权利实现的保障机制,保证农民的各项权利最终成为"可实际行使"的权利.最后,还要建立适应农村环境保护要求的环境法制.     

China-Indian Silk Trade： Current Production and Future Prospects

As an important traditional labor-intensive industry of both India and China, the cocoon silk industry has long made great contributions to the ecological environment protection, rural economic development and the increase in export income of both countries. India is not only a very important cocoon silk trading partner, but an important production competitor of China. In recent years, there has been a large increase in the production and trade of the cocoon silk between China and India; however, China relies heavily on Indian market, which leads to a tendency of further deterioration in the silk trade environment between both countries. The present article makes an empirical study of the cocoon silk resources of the two countries and the scale, product mix and market structure of China-Indian silk trade from 2001 to 2007. Overall silk trading volumes from China to India and market concentration rate are on the increase because of the superiority of Chinese cocoon silk production over that of India. Owing to scattered market share and export that mainly focused on raw materials product, there has been a phenomenon of price reduction and quantity increase. India carries out fierce competition with China in the international market and even imposes antidumping sanction on Chinese silk, which are key factors restricting further increase between China-India trade. Based on the abovementioned facts, the authors aim to put forward suggestions for steadily developing the production and trade of China＇s silk.
