中国已发现的幔源岩浆成因CO2气藏主要分布在与郯庐断裂发育密切相关的东部伸展盆地，两者关系具体表现如下：1．中国东部幔源岩浆成因CO2气藏的空间展布与郯庐断裂保持一致；2．郯庐断裂切割深度达到上地幔；3．沿郯庐断裂岩浆活动强烈，且具幔源特点；4．中国东部伸展盆地自中、新生代以来的演化受郯庐断裂带活动影响。本文主要以郯庐断裂带为主线，结合幔源岩浆成因CO2气藏典型实例，从郯庐断裂构造环境、空间格局和演化过程对幔源岩浆成因CO2的控制作用进行初步归纳和分析。     

厌氧处理原理及其在低浓度有机废水处理中的应用现状

介绍了厌氧处理原理，并对厌氧处理低浓度废水的最新进展进行了较全面的综速，高效厌氧反应器及组合工艺为这一发展提供了可能。高效厌氧反应器中以膨胀颗粒污泥床（ECSB）反应器为首选。其结构及远行特性决定了它在处理低浓度虚水方面具有潜在的优势，但中国EC,SB的应用仅处于研究阶段，尚未有生产规模的EGSB；组合工艺对低浓度废水中污染物去除率极高，出水中COD、NH3-N、TP和SS浓度均可达到较高的排放标准，对生活污水、稀释后的工业有机废水等低浓度有机废水处理具有广阔的前景。     

Transformation of Organic Matter of the Larch Forest Soils in the Northern Taiga of Nizhne-Tungusskoe Plateau, Central Siberia

The evaluation of biospheric role of the boreal forests in the accumulation of carbon is connected with the evaluation of organic matter (OM) pool in soils. The research sites were larch forests, they are situated on Nizhne-Tungusskoe Plateau. Larch forests of feather-moss and lichen types (110 and 380 years old) were formed on 'ochric podbur' soils. Litter stocks are 3.5–4.5 kg m^{− 2} with thickness 10–25 cm. Cryomezomorphic northern taiga soils contains 38–73 t (carbon) ha^{− 1}. Pool of fast mineralized OM has average value 38.1 t (carbon) ha^{− 1}, including 20.5 and 6.4 t (Carbon) ha^{− 1} of labile compounds on surface and in the soil, and 11.2 t (carbon) ha^{− 1} of mobile OM. Microbial mass reaches 1.78–3.47 t (carbon) ha^{− 1}, its proportion is 3.6–4.9% of the total OM carbon. Zoomass of feather-moss larch forest is 0.20–0.61 * 10^{− 2}, in lichen larch forest −0.01–0.07 * 10^{− 2} t (carbon) ha^{− 1}. A pool of resistant to biological decomposition and bonded to mineral soil matrix OM is 17.7 t (carbon) ha^{− 1} and it varies from 18.6 to 29.0 in feather-moss larch forest, and from 6.4 to 17.0 t (carbon) ha^{− 1} in lichen larch forest. Two-years field experiment has been performed to determine transformation rates of various plant litter fractions and to clarify the role of soil biota in these processes. The results showed participation of all biota groups in the decomposition of plant residues caused weight loss of larch-needles and root mortmass. Isolation of organic matter from all-size invertebrate groups leads to some decrease of decomposition activity.     

己二胺有机废液在流化床中焚烧的实验研究

在实验室规模的热态流化床试验台上，进行了含5％己二胺有机废液的焚烧 实验研究，在700－900℃范围内，研究温度及空气过剩系数对NOx沿床高的变化规律，以及它们对NOx排放浓度的影响。实验结果表明，沿高度方向上NOx浓度 逐渐降低，并且存在NO2浓度大于NO浓度这一有趣现象，在900℃下氧量增加有利于密相区NO、NO2浓度的降低，说明在 有氧条件下NH2促进NOx的还原，在不同空气 过剩系数下和然相区出口NOx几乎为零 ，表明900℃是己二胺有机废液焚烧 的合适温度。

A Simulation of Temporal and Spatial Variations in Carbon at Landscape Level: A Case Study for Lake Abitibi Model Forest in Ontario,Canada

Using a case study of the Lake Abitibi Model Forest (LAMF), this study aims to assess the temporal and spatial variability in carbon storage during 1990–2000, and to present a comprehensive estimation of the carbon budget for LAMF's ecosystems. As well, it provided the information needed by local forest managers to develop ecological and carbon-based indicators and monitor the sustainability of forest ecosystems. Temporal and spatial carbon dynamics were simulated at the landscape level using ecosystem model TRIPLEX1.0 and Geographical Information System (GIS). The simulated net primary productivity (NPP) and carbon storage in forest biomass and soil were compared with field data and results from other studies for Canada's boreal forests. The results show that simulated NPP ranged from 3.26 to 3.34 tC ha⁻¹ yr⁻¹ in the 1990s and was consistent with the range measured during the Boreal Ecosystem-Atmosphere Studies (BOREAS) in central Canada. Modeled NPP was also compared with the estimation from remote sensing data. The density of total above-and belowground biomass was 125.3, 111.8, and 106.5 tC ha⁻¹ for black spruce, trembling aspen, and jack pine in the LAMF ecosystem, respectively. The total carbon density of forested land was estimated at 154.4 tC ha⁻¹ with the proportion of 4:6 for total biomass and soil. The analysis of net carbon balance of ecosystem suggested that the LAMF forest ecosystem was acting as a carbon sink with an allowable harvest in the 1990s.
