典型黄土塬区不同植物措施水土保持效应分析

基于黄土高原典型黄土塬区2014-2016年的自然降雨数据及5种植被措施（乔木、灌木、撂荒、人工种草、耕地）下的坡面产流、产沙情况的观测数据,系统分析了不同植被覆盖措施下的黄土坡地水土流失对不同类型侵蚀性降雨的响应机制,结果表明：（1）降水集中于4-10月份,其中引发水土流失的侵蚀性降雨集中于7月、8月。（2）根据最大30分钟降雨强度I₃₀及降雨总量可将侵蚀性降雨分为5种类型,其中小雨量、小雨强类型的降雨是当地发生频率最多的侵蚀性降雨类型;降雨强度最大的Ⅴ雨型降雨侵蚀力最大,降雨量最大的Ⅰ雨型降雨侵蚀力次之,而Ⅱ雨型降雨侵蚀力最低;Ⅴ雨型在观测期内产流产沙量最大。（3）5种植被措施在不同降雨类型下均有明显的水土保持效应,在不同类型降雨下不同植物措施减沙率和减流率变化规律不同。研究结果对于黄土高原地区水土保持及资源可持续利用具有重要的指导意义。     

热液成矿流体中的有机物质

热液流体中的主要有机质包括腐殖物质（t＜50℃）、有机羧酸（t＝80～140℃）、原油（120～180℃）和水溶性甲烷气（180～300℃）。腐殖物质在初始矿源层形成中起重要作用，在腐殖酸缩合成干酪根过程中通过去氧而导致还原的成岩环境，从而有效地防止金属元素在初始矿源石化过程中的分散。有机羧酸是干酪很早期演化的必然产物，富含有机羧酸的油田卤水可以成为MVT铅锌矿的成矿流体。在一定成熟度范围内原油可能成为汞金热液流体的重要有机组分。水溶性甲烷气是铜、铀、金等中低温热液流体的重要有机组分。有机质演化的阶段性决定了相应热液流体中有机质的类型；此外沉积建造的类型、金属元素在油／卤之间分配系数差异和构造条件差异导致了金属矿化分异。

Chance-constrained programming (CCP)abatement of SO_2 emission for acid deposition control in Liuzhou City

A deterministic linear programming model which optimizes the abatement of each SO2 emission source, is extended into a CCP form by introducing equations of probabilistic constrained through the incorporation of uncertainty in the source-receptor-specific transfer coefficients. Based on the calculation of SO2 and sulfate average residence time for Liuzhou City, a sulfur deposition model has been developed and the distribution of transfer coefficients have been found to be approximately log-normal. Sulfur removal minimization of the model shows that the abatement of emission sources in the city is more effective, while control cost optimization provides the lowest cost programmes for source abatement at each allowable deposition limit under varied environmental risk levels. Finally a practicable programme is recommended.

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.
