植物叶片相对吸硫量的研究及在绿化中的应用

为探索北京市本土植物对污染物硫的降解能力，从重度污染区(首钢邻山)、轻度污染区(北京植物园内山上)和对照区(北京周边数个森林公园)分别采集21种植物叶片，采用比浊法消解和定容、IRIS advantage型等离子体发射光谱仪测定其含硫量。分析不同程度污染区植物叶片的相对吸硫量。不同污染区绿化降硫时，考虑选用相应地带叶片净吸硫量大的植物类型。     

Foraging ability in the scorpionfly <Emphasis Type="Italic">Panorpa vulgaris</Emphasis>: individual differences and heritability

According to indicator models of sexual selection, mates may obtain indirect, i.e. genetic, benefits from choosing partners indicating high overall genetic quality by honest signals. In the scorpionfly Panorpa vulgaris, both sexes show mating preferences on the basis of the condition of the potential partners. Females prefer males that produce nuptial gifts (i.e. salivary secretions) during copulation, while males invest more nuptial gifts in females of high nutritional status. Both characters, males' ability to produce nuptial gifts and high nutritional status of females, are known to be reliable indicators of foraging ability. Thus, besides possible direct benefits, both sexes might also obtain indirect benefits in terms of “good foraging genes” by their choice and thereby increase the fitness of their offspring. A prerequisite for this possibility is the heritability of the respective trait. In the present study, we estimated the repeatability and the heritability of foraging ability. Our results indicate (1) a significant repeatability of individual foraging efficiencies in males and females and (2) a heritable component of this trait by a significant parent–offspring regression. These findings suggest that genetic benefits in terms of increased offspring foraging ability might contribute to selection for mating preferences in both sexes.

上海城市与创意产业园区协调发展研究

城市化一方面推动了社会、经济、文化和科技的发展，另一方面，也带来一系列的城市问题，影响了城市可持续发展。创意产业是生产性服务业与消费性服务业的有力组合、文化的思想性与知识的技术性的有机融合、产业组织区域集群化与企业组织小型化的有效结合，是缓解一系列城市问题的有效途径之一。创意产业通过促进城市产业结构升级、优化旧城空间秩序，能够有效地促进城市的可持续发展。本文在探讨创意产业对实现城市可持续发展的作用机理基础上，简述创意产业集聚上海城市空间的历程，以上海卢湾区“8号桥”创意产业园区为个案，分析其企业组织与结构，指出创意产业推动了城市经济的持续发展、社会的稳定进步和文脉的延续，对城市的可持续发展具有良好的示范带动作用。     

协同创新视角下资环专业研究生科技创新能力提升途径

资源循环科学与工程专业硕士毕业生存在规模小、科技创新能力不足、能力施展受限等问题,无法满足产业对高层次人才的需求。究其原因有:(1)新兴专业,其研究生导师队伍建设不健全,人才培养质量参差不齐;(2)交叉专业,其科技创新能力培养方向尚需融合凝练;(3)综合专业,其现有科研平台还不足以支撑学科发展,科技创新能力培养模式还没有完全形成。因此,本学科研究生培养单位应树立协同创新理念,坚持行业需求导向,充分挖掘办学特色和优势,凝练培养方向、完善以科技创新能力培养核心的研究生培养方案;加强师资队伍建设,建立健全科研平台;支持鼓励科技创新实践活动,做好学科前沿追踪;加强校校交流互动,提升硕士点认可度。     

南京市15种树木叶片对铅锌的吸收吸附能力

运用ICP仪对南京市15种主要绿化树木的叶片吸收吸附铅、锌的能力进行了研究。结果表明:15种树木叶片对铅、锌具有一定的吸收净化能力,并依污染物和树种的不同差异明显。在被研究的15个树种中,对铅吸收量较高的树种是雪松和圆柏,对锌吸收量较高的树种是杨树。对铅吸附能力强的树种是雪松,对锌吸附能力强的树种是海桐。叶片吸收和吸附铅的能力强的树种是雪松,叶片吸收和吸附锌的能力强的树种是杨树。最后,通过综合分析得出,杨树和雪松叶片中重金属铅和锌的累积量,可作为铅锌污染监测和评价的重要依据。

Evaluation of biological water purification functions of inland lakes using an aquatic ecosystem model

An effective measure to cope with eutrophication of lakes is to remove nutrients that can cause algal blooming by taking advantage of natural water purification processes. Here the term “purification” is defined, in a wide sense, as the potential role of a water body to contribute to the reduction of pollutants and thus controlling eutrophication. Also regarded as a kind of ecological regulating services, biological purification involves various processes concerning seasonal nutrient fixation, such as uptake by aquatic macrophytes, biofouling onto foliage substrates, feeding by organisms in higher trophic level, and eternal loss or removal of substance from the water. In order to evaluate the water purification ability, a numerical lake ecosystem model highlighting the role of macrophyte colonies in the shore zone was developed and applied to Lakes Suwa, Kasumi and Biwa, as well as five small lakes attached to Lake Biwa.     

Measuring sustainable development - the creative economy perspective

ABSTRACT

World literature presents a variety of approaches to measuring the creative economy at global, national and regional levels, but so far not enough attention has been paid to the issue of sustainability of creative economies. Creative economies do not rely heavily on natural resources which means that their negative impact on the climate is relatively weaker than in the case of other industries. The measurement of sustainable development is an important contribution to the overall efforts in fighting the climate change. Statistical figures show that the share of the creative economy in GDP of the most developed countries is steadily increasing. Therefore, it is legitimate to analyse the sustainable development issues not only through the lenses of utilization of natural resources and environmental issues but also to look at the sustainability challenge for the creative economies. The growth of creative industries may be hindered by scarcity and improper utilization of resouces, but the main threat to the sustainability is the scarcity of intangible resources and goods such as ideas, freedom of thought, leadership, tolerance, quality of education, etc. Based on a literature review, we endeavoured to investigate the sustainability issues which are relevant specifically for the creative economy. In particular, we were interested in the role of local government in supporting the growth of creative economies. This study contributes to the literature in the sense that it provides understanding on how to assess the impact of local government on the sustainability of creative economy.
