国务院印发节能减排工作方案

国务院日前印发国家发改委会同有关部门制定的《节能减排综合性工作方案》，要求各地充分认识节能减排工作的重要性和紧迫性，建立强有力的节能减排领导协调机制，发挥政府主导作用，强化企业主体责任，狠抓节能减排责任落实和执法监督。     

从全局和战略高度研究解决节能减排问题

转变经济发展方式必须从最紧迫、最关键的环节抓起。转变经济发展方式最紧迫、最关键的是节能减排，节能减排中关联度最高、作用最突出的是减排环保。要以污染减排为龙头，带动和促进节能降耗，全面提高节能环保水平，确保实现“十一五”节能减排的各项目标。     

完善电价机制推进电力行业节能减排

电监会4月15日发布《2007年电力行业节能减排情况报告》。报告认为，电力行业节能减排工作是一项系统工程，需要多方统筹协调、共同推动，特别是如果缺乏市场推动力和企业主动性，将难以继续深化。因此总体看，当前我国电力节能减排存在的最大问题是缺乏使节能减排持续有效工作的长效机制。

Exploration of relationships between phytoplankton biomass and related environmental variables using multivariate statistic analysis in a eutrophic shallow lake： A S-year study

Understanding the process of the changing phytoplankton patterns can be particularly useful in water quality improvement and management decisions. However, it is generally not easy to illustrate the interactions between phytoplankton biomass and related environmental variables given their high spatial and temporal heterogeneity. To elucidate relationships between them, in a eutrophic shallow lake, Taihu Lake, relative long-term data set of biotic and abiotic parameters of water quality in the lake were conducted using multivariate statistical analysis within seasonal periodicity. The results indicate that water temperature and total phosphorus （TP） played governing roles in phytoplankton dynamics in most seasons （i.e. temperature in winter, spring and summer; TP in spring, summer and autumn）; COD （chemical oxygen demand） and BOD （biological oxygen demand） presented significant positive relationships with phytoplankton biomass in spring, summer and autumn. However, a complex interplay was found between phytoplankton biomass and nitrogen considering significant positive relationships occurring between them in spring and autumn, and conversely negative ones in summer. As the predatory factor, zooplankton presented significant grazing-pressure on phytoplankton biomass during summer in view of negative relationship between them in the season. Significant feedback effects of phytoplankton development were identified in summer and autumn in view that significant relationships were obser,qed between phytoplankton biomass and pH, Trans （transparency of water） and DO. The results indicate that interactions between phyto：plankton biomass and related environmental variables are highly sensitive to seasonal periodicity, which improves understanding of different roles of biotic and abiotic variables upon phytoplankton variability, and hence, advances management methods for eutrophic lakes.     

Arsenic uptake by arbuscular mycorrhizal maize （Zea mays L.） grown in an arsenic-contaminated soil with added phosphorus

The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment.Non-mycorrhizal and zero-P addition controls were included.Plant biomass and concentrations and uptake of As,P,and other nutrients,AM colonization,root lengths,and hyphal length densities were determined.The results indicated that addition of P significantly inhibited root colonization and development of extraradical mycelium.Root length and dry weight both increased markedly with mycorrhizal colonization under the zero-P treatments,but shoot and root biomass of AM plants was depressed by P application.AM fungal inoculation decreased shoot As concentrations when no P was added,and shoot and root As concentrations of AM plants increased 2.6 and 1.4 times with P addition,respectively.Shoot and root uptake of P,Mn,Cu,and Zn increased,but shoot Fe uptake decreased by 44.6%,with inoculation, when P was added.P addition reduced shoot P,Fe,Mn,Cu,and Zn uptake of AM plants,but increased root Fe and Mn uptake of the nonmycorrhizal ones.AM colonization therefore appeared to enhance plant tolerance to As in low P soil,and have some potential for the phytostabilization of As-contaminated soil,however,P application may introduce additional environmental risk by increasing soil As mobility.

Characteristics of indoor/outdoor PM2.5 and elemental components in generic urban, roadside and industrial plant areas of Guangzhou City, China

Quantitative information on mass concentrations and other characteristics, such as spatial distribution, seasonal variation, indoor/outdoor （I/O） ratio, correlations and sources, of indoor and outdoor PM2.5 and elemental components in Guangzhou City were provided. Mass concentration of PM2.5 and elemental components were determined by standard weight method and proton-induced X-ray emission （PIXE） method. 18 elements were detected, the results showed positive results. Average indoor and outdoor PM2.5 concentrations in nine sites were in the range of 67.7-74.5μg/m^3 for summer period, and 109.9-123.7 μg/m^3 for winter period, respectively. The sum of 18 elements average concentrations were 5362.6-5533.4 ng/m^3 for summer period, and 8416.8-8900.6 ng/m^3 for winter period, respectively. Average concentrations of PM2.5 and element components showed obvious spatial characteristic, that the concentrations in roadside area and in industrial plant area were higher than those in generic urban area. An obvious seasonal variation characteristic was found for PM2.5 and elemental components, that the concentrations in winter were higher than that in summer. The I/O ratio of PM2.5 and some elemental components presented larger than 1 sometimes. According to indoor/outdoor correlation of PM2.5 and element concentrations, it was found that there were often good relationships between indoor and outdoor concentrations. Enrichment factors were calculated to evaluate anthropogenic versus natural elements sources.

分析了上向流厌氧氨氧化生物滤池中氮素化合物浓度、COD和pH变化规律以及ANAMMOX活性和生物量的分布规律,利用数理统计的方法研究了厌氧氨氧化过程中COD和pH与氮素基质浓度之间的关系.结果表明,溶解氧和氮负荷的共同作用使得ANAMMOX活性和生物量的分布沿滤层深度呈"山脊"状不均匀分布;异养反硝化的存在和H+的消耗使得厌氧氨氧化过程中COD和pH分别呈降低和升高趋势;100 mg/L以下的有机物浓度对厌氧氨氧化菌的影响不大,且COD和pH与基质NH4+-N浓度之间呈良好的线性相关关系.本试验中COD-NH4+-N和pH-NH4+-N拟合直线的斜率分别为1.113 8±0.052 2和-0.111 3±0.001 2,置信度为95%,平均相关系数R2分别为0.982 3和0.985 0.

Penetration analysis of elements and bioleaching treatment of spent refractory for recycling

Acidithiobacillus ferrooxidans ATCC23270 and Acidithiobacillus thiooxidans TM-32 were used for bioleaching of spent refractories of aluminium and copper melting furnaces for their recycling.Firstly,penetration of elements into aluminium melting furnace refractory was investigated and it was found that up to 7 cm from surface was contaminated.Comparison on leaching efficiency by the strains ATCC23270 and TM-32 found that the strain ATCC23270 could treat larger amount of the refractories than the strain TM-32 could do.In the experiment of bioleaching of spent refractory aluminium melting furnace by the strain ATCC23270,high leaching efficiency were obtained on Al,Si,and Ca,and extremely low leaching performance was,however,shown on the rest of elements i.e.,Na,Mn,and Zn.Under the strain TM-32 use,relatively high leaching performance was recognized on Al,Si,Ca,Na,Mn,and Zn.In the experiment of bioleaching for spent refractory copper melting furnace,almost the same leaching trends were shown on Cu,Zn,Al,and Si under the strains ACTT23270 and TM-32 uses.     

环境正义研究前沿及其启示

环境正义不仅是重大的现实问题,也是不同学科和领域研究的焦点。通过对国内环境正义研究文献的梳理,比较分析环境正义所涉学科、内容和方法后发现：环境正义研究呈现出多学科视角、多元化主题和学科交叉趋势,但研究体系不够完善,缺乏理论创新;亟待构建中国特色环境正义理论体系和分析框架,总结中国环境正义研究案例和解决模式;环境正义概念多而不统一,混杂而不明确,需进一步厘清和辨明;考虑多维内涵、多重维度和多维原则,建构和完善环境正义概念体系;环境正义问题主要表现在多尺度区域和多类型群体两个层面,环境强势群体（区域）与弱势群体（区域）的环境权责不对等是焦点;城乡环境正义问题广受关注,需加强经济弱势地区和环境弱势地区环境正义研究;解决环境正义问题的政策措施缺乏系统性考量和可操作性,在具体的社会文化和地方情境中探讨环境正义及其解决之道是重点;按照问题的轻重缓急,分区域分群体逐步消除环境不正义;环境正义评价标准欠缺,不同学科数据和方法交叉融合不足。未来环境正义研究的重点和难点在于：建构一个问题导向的、跨学科交叉的环境正义理论框架;精确表征和测度环境（不）正义;模拟多尺度、多主体的环境正义演变过程;基于地方性加强环境正义的典型案例研究。     

Developing a Regional Open Space Strategy (ROSS) for Central Puget Sound,Washington State,USA

Ecosystem services provided by the landscapes of regions and cities are critical to human and environmental health, quality of life, environmental justice, biodiversity and climate mitigation and adaptation. In the Pacific Northwest region of the US, a team led by the University of Washington Green Futures Lab is working to identify, conserve and enhance regionally-significant landscapes and to evaluate their contributions as ecosystem or “open space” services. This paper outlines the goals and planning methods of the ongoing Regional Open Space Strategy for Central Puget Sound (ROSS) project, and the frameworks and processes being developed to evaluate ecosystem and open space services in order to inform and influence local and regional governance structures and decisions.
