Methodological and Practical Considerations for Developing Multiproject Baselines for Electric Power and Cement Industry Projects in Central America

The Lawrence Berkeley National Laboratory (Berkeley Lab) and the Center for Sustainable Development in the Americas (CSDA) conducted technical studies and organized two training workshops to develop capacity in Central America for the evaluation of climate change projects. This paper describes the results of two baseline case studies conducted for these workshops, one for the power sector and one for the cement industry, that were devised to illustrate certain approaches to baseline setting. Multiproject baseline emission rates (BERs) for the main Guatemalan electricity grid were calculated from 2001 data. In recent years, the Guatemalan power sector has experienced rapid growth; thus, a sufficient number of new plants have been built to estimate viable BERs. We found that BERs for baseload plants offsetting additional baseload capacity ranged from 0.702 kgCO2/kWh (using a weighted average stringency) to 0.507 kgCO2/kWh (using a 10th percentile stringency), while the baseline for plants offsetting load-following capacity is lower at 0.567 kgCO2/kWh. For power displaced from existing load-following plants, the rate is higher, 0.735 kgCO2/kWh, as a result of the age of some plants used for meeting peak loads and the infrequency of their use. The approved consolidated methodology for the Clean Development Mechanism yields a single rate of 0.753 kgCO2/kWh. Due to the relatively small number of cement plants in the region and the regional nature of the cement market, all of Central America was chosen as the geographic boundary for setting cement industry BERs. Unfortunately, actual operations and output data were unobtainable for most of the plants in the region, and many data were estimated. Cement industry BERs ranged from 205 kgCO2 to 225 kgCO2 per metric ton of cement.     

吉林省的风能潜力(英文)

近两年我国电力突然短缺,已经引起政府的高度重视。由于我国风电发展的紧迫性和风电发展的潜力,特别是国际上正在如火如荼地开发风电的情景,中国- 奥地利政府间双边合作计划将风电评估列入2001～2003 年度合作计划,论文是该计划的成果之一。以我国吉林省为研究对象,采用广泛使用的风机选址算法和空间分布诊断程序( WAsP和ZAWIMOD2),运用数字地形图和遥感资料获得的土地利用图,进而得到数字化的表面粗糙度,再对吉林省的风能潜力进行估算。完成了近1km² 分辨率的距地面60m高度的风速和风能密度计算,并制作了它们的分布图。这是我国第一次在较大区域上估算距地面60m 高度的风速和风能密度,其方法对我国风电资源的评估有重要的借鉴作用。结果显示最有效的风能资源在吉林省的中西部地区,而南部和东部的高风资源区位于山脊和山顶,对风能的开发有一定的限制。     

秦山核电站运行后对邻近海域生态环境及其水质影响评价

通过对秦山核电站运行前后相隔近７ ａ 的工程区邻近海域四季度月生物与非生物环境生态各要素的两次调查分析，进行了Ⅰ期工程运行以来海域生态环境及水质状况的影响评价。结果认为，秦山海域具典型强潮河口湾生态特征，营养盐丰富，而生产力低下。潮汐、径流和湾外海水入侵是导致海洋环境要素季节和年际变化并直接影响海洋生物结构的主要因子。水体富营养化指数上升是沿岸工业和生活污水大量排放的结果。核电站运行中冷却水的热排放由于杭州湾特殊的海底地形和强潮混合的水体环境对附近水域的热升温效应不明显。秦山Ⅰ期工程运行以来对海域生态环境和水质变化未见明显影响

从植被演替和抗风性研究包兰线沙坡头段人工植被稳定性

运用群落演替与风沙流因子分析相结合的方法论证了群落的稳定性。在沙坡头地区,以油蒿为主的人工群落在长期的自然演替过程中已达到与生境条件相互适应的动态稳定过程。通过沙坡头与周边地区植被演替的比较研究,表明了该地区现有植被正形成(或已形成)偏途顶极序列,该植被在相当长的时间内会稳定存在,这些演替可促使沙坡头地区的人工植被向更为稳定的人工+自然复合生态系统以及自然生态系统方向变化。此外,风洞实验结果显示,沙坡头现有主要植被和地表能够抵抗较大风沙流胁迫,已形成了能够忍耐沙尘暴的生态系统。
