市场转型对中国环境治理结构的影响——国家污染物减排指标的分配机制研究

国家统计局数据显示,2006年我国节能减排任务均远未实现国家"十一五"规划开局之年的目标,特别是主要污染物排放总量不降反升.本文在分析了中国环境治理体系和国家"十一五"规划主要污染物减排指标分配机制的基础上,研究了市场转型对中国环境治理结构的影响.中国的市场转型可以抽象为以"分权让利"、"市场化"和"工业化"为主要特征的结构演进过程.文中提出,中国市场转型过程对环境治理结构造成了重大影响,而环境治理的各项措施反过来也应与市场转型相适应.当前中国主要污染物减排指标没有实现达标的重要原因是国家污染物减排指标的分配机制无法适应我国市场转型的要求.为此,本文提出一系列国家主要污染物减排指标分配机制的政策建议.

Ivemark syndrome with agenesis of the corpus callosum: a case report with a review of the literature

Asplenia associated with situs ambiguus, symmetric liver, bilateral trilobulated lungs, and a complex heart defect was diagnosed on autopsy in a 14-day-old infant. Furthermore, examination of the brain displayed agenesis of the corpus callosum (ACC) with pachygyria and hydrocephalus. The characteristic association of asplenia with visceroatrial heterotaxia is traditionally named after the Swedish pediatrician, Ivemark. Although exceptional, association of Ivemark syndrome with callosal agenesis has been reported recently. The concept of ‘developmental fields’ describes morphogenetically reactive units of the embryo determining and controlling the development of complex structures in a hierarchical manner. Lateralization defects such as situs inversus, asplenia or polysplenia due to defective left–right axis development, as well as decussation defects such as ACC, are considered as defects of the primary developmental field. Therefore, additional callosal agenesis in Ivemark syndrome may be a coherent and synchronic defect in the primary developmental field rather than a causally independent malformation.

乌江干流中上游水电梯级开发水温累积效应

以乌江流域洪家渡库尾至乌江渡坝下的水电工程干扰典型段为研究区域，利用建坝前后的水温实测资料，采用建坝前天然水温和建坝后下泄水温比较法，对乌江干流梯级水库水温时空分布特征进行分析。研究结果表明：对天然水温改变最大的电站为洪家渡和乌江渡，前者是受水库水温结构自身影响，后者是梯级联合运行的结果；梯级联合运行使库区水温分层有所减弱，随着时间的推移或上游梯级电站的建成，电站下泄水温年变化过程趋于均化，与天然水温的延迟也越加明显；不同的水库水温结构对水温累积效应的影响也各不相同，稳定分层型水库对水温累积具有正效应，混合型水库具有负效应，过渡型水库处于两者之间，体现了梯级电站的水温累积影响，为研究减缓下泄低温水的对策措施提供依据和参考。

Responses of plant, insect and spider biodiversity to local and landscape scale management intensity in cereal crops and grasslands

The aim of this study was to determine the relative effects of landscape scale management intensity, agroecosystem type, local management intensity and edges on diversity patterns of functional groups of plants, carabid beetles, spiders and grasshoppers. Nine landscapes were selected differing in percent intensively used agricultural area (IAA), each with a pair of organic and conventional winter wheat fields and a pair of organic and conventional mown meadows. Within fields, plants were surveyed in the edge and in the interior. Carabid beetles and spiders were captured by funnel traps, while grasshoppers were sweep-netted in the meadows. Diversity patterns of study organisms were affected both by local variables (local management, agroecosystem type and within-field position) and by landscape scale management intensity. Species richness of grasses, presumably because of sowing low-diversity mixtures, and hunting spiders decreased with percent cover of IAA. Meadows differed from wheat fields in that they had higher species richness of forbs and grasses, as well as higher densities of hunting spiders. In contrast, more carabid individuals, especially of non-carnivore species, were captured in wheat fields. In field edges with their reduced management intensity and increased immigration, species richness of plants, carabids and spiders was higher than in the interiors regardless of agroecosystem type and management. Organic management enhanced forb richness and cover in both agroecosystem types. Organic management also increased grass cover in wheat fields, but not in meadows, and promoted species richness of non-carnivore carabids and hunting spiders, but not grasshoppers. The results show that agri-environmental management needs to be targeted to the agroecosystem's field size, because higher edge area led to higher species richness. Organic management affected several functional groups positively (forbs, non-carnivore carabids, hunting spiders), while lower landscape scale management intensity only increased species richness of grasses and spiders. The great differences in responses of functional groups to local cereal and grassland as well as landscape management suggest implementing more scale and group specific targets for agri-environmental schemes to improve their efficiency.
