In this study, a ‘‘direct-starting'' procedure was used to activate a single-chamber biocathode microbial electrolysis cell(MEC) and the development of a biocathode was studied through output current curves and cyclic voltammograms. It only took 163 h for a successful start-up, and a current density of 14.75 A/m^2 was obtained. In the formal hydrogen-production stage, it was found that the biocathode MEC was comparable with the Pt/C cathode MEC in terms of current density and energy efficiency, and the hydrogen recovery, cathodic hydrogen recovery, and hydrogen production rate of the biocathode MEC were 71.22% ± 8.98%, 79.42% ± 5.94%, and 0.428 ± 0.054 m^3 H_2/m^3 days, respectively, which were slightly higher than those obtained with the Pt/C cathode MEC. Besides, under the effect of applied voltage, the microbial populations in the anodophilic biofilm of MEC(MECan) and the cathodophilic biofilm of MEC(MECca) were less diverse than those of the original aerobic activated sludge(AAS) and the anodophilic biofilm of MEC(MECan). Furthermore, the microbial community structures evidently differed between MECan/MECca and AAS/MFC.

China) Northeast Institute of Geography and Agricultural Ecology Chinese Academy of Sciences Changchun P. R. China

There is great potential for agriculture in saline-alkali soil area in songnen Plain, Northeast China. But the sustainable crop production in this area has been restricted by a few of main factors, such as less precipitation, h igher evaporation and frequent drought, high salinity and alkalinity, high excha ngeable sodium content and poor infiltration of the soil, and insufficiency and low availability in nutrition. It is also considered that there are a few of fav orable conditions for agricultural development in this region, such as sufficien t light and heat resources, rich ground water resources, plenty of manure produc ed by livestock, and so on. At the same time, scientific management and measurem ents have been employed; rational irrigation and drainage system has been establ ished; reclamation, amendment and fertilization of soil, and suitable strategies of cropping practices have been made for the sustainable development of agricul ture. Great progress has been made during 1996-2000.

合理的城市体系分布是资源空间配置优化和区域经济协调发展的必要条件。本文从区域城市化发展模式的角度出发,分析了多中心发展对地区收入差距的影响机制,并创新性地应用DSMP/OLS夜间灯光数据,对省份内部的空间结构和地区收入差距进行测度,进而实证考察了多中心发展带来的地区收入差距缩减效应。研究发现,多中心空间发展模式的确有利于缩小地区收入差距,且多中心发展的地区收入差距缩减效应主要通过优化区域内中小城市的产业结构和加快区域内的商品流通来实现。本文还考察了经济发展、基础设施以及省域平均距离对于多中心发展的地区收入差距缩减效应的影响。结果表明,在经济发展水平较高、基础设施条件较好且城市间距离适中的地区,多中心发展对地区收入差距的缩减效应更为明显。本文的研究不仅对中国缩小地区差距方面的政策制定具有重要的启示,也为未来城镇化发展的道路选择提供了一定的经验依据。
