上海设施蔬菜主要品种污染物含量调查评估

通过对上海郊区单栋大棚、连栋大棚和现代化智能温室生产的叶菜类和茄果类设施蔬菜的主要品种污染物（农药和硝酸盐）含量抽样调查，并以附近大田蔬菜作为对照，分析结果发现，上海郊区设施蔬菜农药和硝酸盐的污染物含量普遍高于大地蔬菜，且超标状况比较严重。究其因，设施蔬菜生产较常规大田蔬菜生产农药与化肥使用水平高，而且在封闭环境条件下污染物降解速度慢，容易残留或积累超标。     

昆明城市太阳辐射资源及利用现状初探

利用有关资料,对昆明城市太阳辐射资源和利用现状进行了初步探讨。分析得知,昆明地区太阳辐射具有独特的分布特征,为太阳能的利用提供了良好的环境条件;太阳能热水器在干季晴好天气时增温效果显著。通过对不同太阳能热水器普及率和不同增温率的太阳能热水器等的计算,可以看出昆明城市太阳能热水器的节能效应是十分显著的,但仍有较大空间。加大昆明城市太阳能热水器的普及工作对于城市太阳能利用将是十分重要的。

Carbon Dioxide Balance of Wood Substitution: Comparing Concrete- and Wood-Framed Buildings

In this study a method is suggested to compare the net carbon dioxide (CO₂) emission from the construction of concrete- and wood-framed buildings. The method is then applied to two buildings in Sweden and Finland constructed with wood frames, compared with functionally equivalent buildings constructed with concrete frames. Carbon accounting includes: emissions due to fossil fuel use in the production of building materials; the replacement of fossil fuels by biomass residues from logging, wood processing, construction and demolition; carbon stock changes in forests and buildings; and cement process reactions. The results show that wood-framed construction requires less energy, and emits less CO₂ to the atmosphere, than concrete-framed construction. The lifecycle emission difference between the wood- and concrete-framed buildings ranges from 30 to 130 kg C per m² of floor area. Hence, a net reduction of CO₂ emission can be obtained by increasing the proportion of wood-based building materials, relative to concrete materials. The benefits would be greatest if the biomass residues resulting from the production of the wood building materials were fully used in energy supply systems. The carbon mitigation efficiency, expressed in terms of biomass used per unit of reduced carbon emission, is considerably better if the wood is used to replace concrete building material than if the wood is used directly as biofuel.     

昭通市水污染现状及防治对策探讨

昭通市内的两条河流均已受到污染，其中主要纳污的秃尾河TP、TN、CODCr和BOD5已属劣V类水指标。各河流每年流入金沙江的BOD5为386．9t，CODCr为1021．4t，TN为276t，TP为36．6t。应从加强重点行业治理、推行排污许可证制度等6方面采取措施加以防治。

旅游城市环境规划优化方法与应用研究(Ⅰ)不确定性多目标规划模型

以旅游城市环境系统的综合性、多目标性、动态性和不确定性的特征出发，提出用不确定性模糊多目标规划（IFMOP）模型来解决旅游城市 环境规划优化问题。通过建立旅游城市环境不确定性模糊多目标规划系统模型（IFMOPMTCE），使旅游城市环境系统的特性在模型建立和求解过程中得以充分反映，同时也有效地协调了环境经济等目标之间的矛盾与冲突，该研究为旅游城市环境规划工作提供了一种较为有力的工具。     

Institutional and cost implications of multi-project baselines

Starting from a theoreticalnotion of capacity building this paperfocuses on the implications ofmulti-project baselines for costs andinstitutions. Availability of data and thelevel of data aggregation determine to alarge extent the cost of derivingmulti-project baselines. For localinstitutions this implies that theircapacity development needs are linked todecisions made on strictness of baselines.The initial higher costs of multi-projectcalculations in the development stage areeasily offset once more projects will usesuch a baseline. This paper argues theseinitial demands are not as high asexpected. Multi-project approaches willreduce transaction costs, especially forsmall-scale projects, will reducevalidation costs and likely reduce humanresource demands in other stages of theproject cycle.
