Studies on China’s Green and Low-carbon Construction [PDF]

open access: yes, 2016
全球气候变暖促使绿色低碳化转型成为建筑业可持续发展的必经之路。国内外对绿色低碳建筑业的研究主要围绕建设过程中的的碳排放量测算与影响机制来进行研究,以及技术路径、管理策略等问题展开,对绿色低碳建筑业的量化评价和政策措施等问题还缺乏全面的系统性研究。从最新的国家“一带一路”发展战略对建筑业的要求、以及建筑业本身的可持续性发展前景来看,这些方面的研究价值巨大。针对已有文献的不足与缺陷,本文从能源消费产生的二氧化碳排放角度入手,就中国建筑业绿色低碳化发展实现路径进行了深层次量化研究与讨论。主要的研究内容包括: (

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Study on Green Sustainable Technology of Buildings in south Fujian [PDF]

open access: yes, 2016
闽南地区有石厝、土楼、大木架瓦房、竹楼、风雨桥等诸多历史悠久的地方建筑,旅游发达,宜于居住。但在大多数地区,村镇民居一直尚不被关注,有的已破败不堪。新建的村镇建筑大部分模仿现代城市建筑,采用钢筋混凝土,摈弃了当地千百年来形成的因地制宜的传统建筑形式,继而带来范围更大的资源浪费、生态破坏,得不偿失。 本文主要围绕闽南村镇建筑的绿色可持续发展问题进行探讨,进行了以下工作: 1)对闽南地区几个典型自然村进行实地调研。分别就建筑的结构抗震性能,墙、窗、屋面等围护结构,及能源使用情况进行调查 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Efficient Simulation Methods for Reinforced Concrete Columns with Encased Steel in High-rise Building Structures [PDF]

open access: yes, 2016
型钢混凝土柱在建筑结构中往往是主要的承重构件之一,使用合适的数值模型分析其力学性能对高层结构抗震分析有重要的意义。本文综述了目前文献中已有的低含钢率恢复力模型相关研究,分析了其理论、计算流程和算法,并在通用有限元软件OpenSees中编程实现。本文详细推导了模型中基本参数的确定方法,并用于模拟实际高层建筑结构中的型钢混凝土柱。首先,本文用恢复力模型模拟了单根型钢混凝土柱的试验,通过对比验证了模型的精度,研究了其计算效率。其次,本文将恢复力模型用于理想32层高层结构中的单排型钢混凝土构件静、动力分析中 ...
