沈阳城市居民生活消费的生态足迹动态分析

在可持续发展的理论基础上,运用生态足迹模型计算2000-2009年沈阳城市居民人均生活消费的生态足迹,定量分析了10年来沈阳城市居民人均生活消费生态足迹的发展趋势、组成结构,评价了可持续消费的状态,探讨沈阳实现可持续消费的对策,为今后城市居民转变消费模式、实现可持续消费提供借鉴．研究结果表明,2000-2009年沈阳市城市居民消费的生态足迹总体呈现上升趋势,由1．3826 hm2/人增至1．8729 hm2/人,增长36．46％,其中化石能源用地增长尤为显著,增长354．82％．认为沈阳市10年来一直是生态赤字,且赤字的增幅越来越大．     

关于环境设计与社区居住模式关系的研究

社区空间在人们的生活中扮演着重要的角色,一个富有生机的社区是由空间和使用者共同创造的,它们之间存在着密切的关联,制约着一个社区的使用率。弄清它们之间的关系,并找出它们的规律和特征并运用到设计当中,就能设计出人性化的居住空间。     

Three new species of the genus Belbolla (Nematoda: Enoplida: Enchelidiidae) from the Yellow Sea,China

Three new species of free‐living marine nematodes of the genus Belbolla: Belbolla huanghaiensis sp. nov., Belbolla stenocephalum sp. nov. and Belbolla warwicki sp. nov. from the Yellow Sea, China, are described and illustrated. Belbolla huanghaiensis can be separated from other species in the Belbolla genus by the number of oesophageal bulbs (nine), the length of the spicules and gubernacular apophysis, and the size of the two winged precloacal supplements. Belbolla stenocephalum can be separated from other species by the number of oesophageal bulbs (eight), the length of the spicules and the structure of gubernacular apophysis. Belbolla warwicki sp. nov. is characterized by the number of oesophageal bulbs (seven), reduced precloacal supplements and the structure of gubernacular apophysis. A key to the genus Belbolla is provided to facilitate species identification. Types are deposited in the College of Life Science and Technology, Ocean University of China.     

A new genus and three new species of free‐living marine nematodes from the Yellow Sea,China

One new genus, Paramphimonhystrella gen. nov., and three new species of free‐living marine nematodes in this genus, P. elegans sp. nov., P. minor sp. nov., and P. sinica sp. nov., are described and illustrated from the Yellow Sea, China. Paramphimonhystrella gen. nov. differs from the similar genus Amphimonhystrella by the elongated buccal cavity, cervical setae and large caudal glands. Paramphimonhystrella elegans sp. nov. is characterized by ovoid amphids and spicules with a small hook at distal end and cylindrical part of tail shorter than conical part. Paramphimonhystrella sinica sp. nov. is characterized by circular amphids, wide buccal cavity, spicules with blunt tip, and cylindrical part of tail longer than conical part. Paramphimonhystrella minor sp. nov. differs from the other two species by its smaller body (shorter than 800 µm), circular amphids, and spicules with sharp tip. The type species of this new genus is P. elegans gen. nov. and sp. nov. Types are deposited in the College of Marine Life Sciences, Ocean University of China.     

基于GPCA的中部省际农村居民生活水平动态分析

文章首先构建评价农村居民生活水平的指标体系,之后运用全局主成分分析法(GPCA),实证研究了我国中部各省农村居民从2001年-2006年生活水平的时间演变,并对结果进行了比较分析。     

合成生物学、超材料和人工智能的融合

提出了合成生物学、超材料与人工智能互相融合的思想,研究领域从合成生物学、超材料、人工智能拓展为生物超材料/超生物材料、智能超材料、智能合成生物学/生物人工智能,再到智能生物超材料,这种三向、三位一体的交叉融合为科学技术创新发展提供了新思路。     

四川乐山大佛地衣与苔藓群落中的微生物多样性

为了探究生物侵蚀微生物的种类,通过高通量测序手段对乐山大佛地衣(lichen,LI)和苔藓样本进行了微生物(细菌、古菌和真菌)多样性分析.结果发现:地衣、活苔藓(living moss,LM)和苔藓残体(dead moss residue,DM)样本中的细菌和真菌组成在组内样本之间能进行聚类,组间差异也能良好区分;在细菌群落中,地衣与活苔藓样本中的细菌组成较为相似,两个样本的优势细菌均为蓝细菌(Cyanobacteria)和醋酸菌(Acetobacteraceae);在真菌群落中,地衣样本的优势真菌是煤炱目(Capnodiales),但其在活苔藓样本中含量较少,活苔藓样本的优势真菌是子囊菌门(Ascomycota),且其在地衣和苔藓残体样本中也有一定含量(7.47%～52.6%);古菌群落的组内差异较大,其中与氮转化相关的泉古菌(soil Crenarchaeotic group,SCG)总体丰度占比较高,并发现了较多未归类古菌(unclassified-k-norank).
