我国探矿权资产化、证券化的模式及设想

探矿权资产化、证券化是我国改革探矿业投融资体制，解决探矿业资金瓶颈问题的关键。本文从制度建设、机构投资者的发展状况等方面分析了我国初步推行探矿权资产化、证券化的有利条件．指出了探矿权资产化、证券化的三种模式。并以基金模式和股权模式为例提出了实施探矿权资产化、证券化的步骤设想。     

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。     

区域排污权交易模型研究

本文在分析了排污权交易研究进展的基础上，指出区域污染权交易比传统的排污权交易意义更大，并提出排污权交易地区交叉补贴的设想：将发达地区的排污权交易所得向欠发达地区转移，以解决欠发达地区产业结构调整乏力以及对发达地区的二次污染和发达地区环境容量资源短缺问题。在不考虑交易成本的假设下，通过建立不同地区排污权交易模型以确定排污权交易总量及其交易价格以及交易所获净增纯收益等。太湖流域由于经济最为发达，环境问题十分突出，是目前我国最适宜率先进行区域排污权交易试点的地区。通过假定太湖流域无锡和常州两市进行排污权交易，并利用两市1991—2000年的环境统计资料等相关资料进行了验证。计算结果表明区域排污权交易不仅具有明显的经济和环境效益，而且也是协调环境区域矛盾的重要手段。因此，不同地区间进行排污权交易在我国具有重要意义，在太湖流域等经济发达地区收效尤其明显。     

Identification of potential electrotrophic microbial community in paddy soils by enrichment of microbial electrolysis cell biocathodes

Electrotrophs are microbes that can receive electrons directly from cathode in a microbial electrolysis cell (MEC). They not only participate in organic biosynthesis, but also be crucial in cathode-based bioremediation. However, little is known about the electrotrophic community in paddy soils. Here, the putative electrotrophs were enriched by cathodes of MECs constructed from five paddy soils with various properties using bicarbonate as an electron acceptor, and identified by 16S rRNA-gene based Illumina sequencing. The electrons were gradually consumed on the cathodes, and 25%–45% of which were recovered to reduce bicarbonate to acetic acid during MEC operation. Firmicutes was the dominant bacterial phylum on the cathodes, and Bacillus genus within this phylum was greatly enriched and was the most abundant population among the detected putative electrotrophs for almost all soils. Furthermore, several other members of Firmicutes and Proteobacteria may also participate in electrotrophic process in different soils. Soil pH, amorphous iron and electrical conductivity significantly influenced the putative electrotrophic bacterial community, which explained about 33.5% of the community structural variation. This study provides a basis for understanding the microbial diversity of putative electrotrophs in paddy soils, and highlights the importance of soil properties in shaping the community of putative electrotrophs.     

论环境参与权

环境参与权是公民享有的一项重要环境权利。它包括参与环境立法权、环境行政听证权、参与环境决策权和环境监督权，确立环境参与权具有重要意义，但我国现行立法很不完备，需要进一步完善。     

水葫芦对Zn2+、Cd2+和Fe3+的去除速率

通过静态水培实验和原子吸收分光光度法的测定,发现水葫芦对个别重金属离子累积去除率头两天为Zn≈Cd>Fe,以后为Fe>Zn>Cd;5天中,Cd2 在水葫芦老黄茎叶中的积累量增长了130 0倍;在混合离子培养液中,Zn2 的去除速率明显下降,而Cd2 和Fe3 变化不明显。表明水葫芦在治理含镉废水方面有良好的应用前景。     

试论高职高专教育毕业生质量标准

本文详细地论述了什么是高职高专教育的毕业生质量标准和为什么要制定毕业生质量标准以及制定毕业生质量标准的原则、毕业生质量标准的内容及方法。     

Concept of common interests of mankind in the global environmental protection

The concept of common interests of mankind in the environmental protec-tion spurred -by the internationalized and globalized environmental problems are discussed in this paper. While making challenges for many principles and rules of international law and the traditional conception of national security, the concept does play its role in strengthening the environmental protection. However, it cannot be neglected that diflerent national interests pose an obstacle to the realization of the common interests of mankind in the envirormental protection. The article concludes that whether the concept plays its greater role in the environmental protection will depend on many factors, such as the spread of environmental awareness, the revision of the traditional conception and the balanced development of the world economy.     

论我国自然资源产权制度的改革

我国自然资源产权制度长期以来界定不清晰和不合理，造成自然资源配置的效率损失很大，本文根据许多实例和交易成本理论来说明５０年代中期以来我国自然资源的一些主要产权制度的利弊，并提出未来改革的一些设想。
