浅论国家环境权

随着全球环境的日益恶化和公民环保意识的不断增强，环境权理论迅速发展。国家环境权作为一项重要的环境权。在环境法理论逐步变革和权利内涵不断演进的趋势下，已成为法学界研究探讨的重要课题。通过分析国家环境权的国内、国际法律基础。论证了国家环境权的确立。利用类比的方法。阐述了国家环境权与其他宪法权利的不同之处。从权利义务的对等统一和国内国际两个层面。重新归纳了国家环境权的内容。初步构建了国家环境权的基本理论框架。     

Sustainability: a Dissent

Abstract:  Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchot-era conservation (and thus ignores the many lessons learned since then); it need not be linked to land, to the land's functioning, or to any ecological science; it need not include a moral component; it is consistent with the view of humans as all-powerful manipulators of the planet; and, in general, it is such a malleable term that its popularity provides only a facade of consensus. When sustainability is defined broadly to include the full range of economic and social aspirations, it poses the particular risk that ecological and biodiversity concerns will be cast aside in favor of more pressing human wants. Given these many defects, the conservation movement should discard the term in favor of a more alluring goal, attentive to nature and its ecological functioning. A sound goal would incorporate and distill the considerable ecological and moral wisdom accumulated since Pinchot's day while giving conservationists the rhetorical tools needed to defend the land against competing pressures. In our view, conservation would be well served by an updated variant of "land health," Aldo Leopold's ecologically grounded goal from the 1940s. Land health as an independent understanding should set the essential terms of how we live and enjoy the earth, providing the framework within which we pursue our many social and economic aims.     

中国工业园区绿色发展政策对比分析及对策研究

为了提升我国工业园区绿色发展水平,对目前我国工业园区发展历程、现状特征进行了分析,对工业园区绿色发展政策进行了梳理和对比,并结合工业园区绿色发展中存在的问题提出了对策建议.研究表明:①我国工业园区经历了快速发展、调整发展和科学发展等阶段,在经济发展、资源与能源优化利用、污染减排等方面成效显著.②我国工业园区绿色发展的相关政策主要体现在国家生态工业示范园区创建、园区循环化改造、国家低碳工业园区试点、绿色园区建设和UNIDO绿色工业园区创建等工作中,这些政策在推动主体、实施路径、侧重方向上各不相同又各有特色,对推动工业园区节能减排绩效明显.③目前,我国工业园区绿色发展存在的问题主要表现在重视程度有待提升、风险防范意识有待加强、创新能力有待提高等方面.为此,提出了我国工业园区绿色发展对策建议:积极践行绿色发展理念,推进园区绿色化、生态化、低碳化建设,实现经济环境双赢;注意环境风险防控,确保环境安全;创新管理机制,强化监督管理.      

Removal and desorption of chromium in synthetic effluent by a mixed culture in a bioreactor with a magnetic field

Two chromium removal experiments were performed in bioreactors with and without a magnetic field under the same conditions.The release of the chromium present in the biomass was tested in two experiments one with the initial pH of the medium and one with pH 4.0.The objective was to remove Cr(Ⅵ) and total Cr from the effluent,this was carried out by placing biological treatments of synthetic effluent contaminated with 100 mg/L of Cr(Ⅵ) in a bioreactor with neodymium magnets that applied a magnetic field(intensity85.4 mT) to the mixed culture.The removal of Cr(Ⅵ) was approximately 100.0% for the bioreactor with a magnetic field and 93,3% for the bioreactor without a magnetic field for9 hr of recirculation of the synthetic effluent by the bioreactor.The removal of total Cr was61.6% and 48.4%,with and without a magnetic field,respectively;for 24 hr.The desorption of Cr(VI) in the synthetic effluent was 0.05 mg/L,which is below the limit established by Brazilian legislation(0.1 mg/L) for the discharge of effluent containing Cr(Ⅵ) into bodies of water.The results obtained for the removal of chromium in synthetic effluent suggested that there was no significant influence on the viable cell count of the mixed culture.The desorption of Cr(Ⅵ) in synthetic effluent after bioadsorption of chromium by the mixed culture in the process of removal of chromium in bioreactors with and without a magnetic field was not significant in either of the experiments with different initial pHs.     

新时代国土整治与生态修复转型思考

针对全球变化影响下的国土空间和生态系统,生态文明建设和国土空间规划是中国在新时代的积极响应,国土整治与生态修复的转型和提升成为必然要求。在介绍国土整治与生态修复概念内涵的基础上,指出中国国土空间生态环境问题的复杂性和生态文明建设的新理念要求决定了国土整治与生态修复的转型。从工作理念、理论基础、技术体系和制度建设等方面,分析了当前国土整治与生态修复工作中存在的不足,主要包括整体综合理念滞后、理论基础体系欠缺、技术支撑相对薄弱、体制机制不尽完善等方面。针对这些不足,提出了新时代国土整治与生态修复转型的路径和策略,主要策略包括强化系统思维、提升理论体系、加强技术支撑、完善机制建设等内容,以期为国土整治与生态修复推进美丽中国建设提供科学依据。     

魅力国土空间:重塑区域特色的国土空间规划策略

国土空间规划的提出使我国的规划体系进入到新的发展时期与发展语境,国土空间开发方向已从生产空间为主导转向生态、生活、生产空间相协调。如何将基于“三生空间”概念的传统国土空间认知提升到丰富文化脉络、生态特征、生活基础的复合魅力国土空间,如何对不同区域的发展进行侧重,杜绝对单一发展模式的盲目跟风,是国家和地方面临的共同重大主题。结合国土空间在历史与现实不同时期的发展表征和形成原因,在回溯空间认知过程、反思空间规划实践的基础上,厘清了魅力国土空间的概念与内涵,提出国土空间规划体系下魅力国土空间的关注焦点,从区域发展平衡、管控弹性调整、空间要素流动、发展目标优化等方面阐述了魅力国土空间的作用与功能。

Selecting Socio-Economic Metrics for Watershed Management

The selection of social and economic metrics to document baseline conditions and analyze the dynamic relationships between ecosystems and human communities are important decisions for scientists, managers, and watershed citizens. A large variety of social and economic data is available but these have limited use without theoretical frameworks. In this paper, several frameworks for reviewing social-ecosystem relations are offered, namely social sanctions, sense of place, civic structure, and cultural differences. Underlying all of these frameworks are attitudes, beliefs, values, and norms that affect which questions are asked and which indicators are chosen. Much work and significant challenges remain in developing a standard set of spatially based socio-economic metrics for watershed management.
