A comprehensive review on green buildings research: bibliometric analysis during 1998–2018

Environmental Science and Pollution Research - Buildings account for nearly 2/5ths of global energy expenditure. Due to this figure, the 90s witnessed the rise of green buildings (GBs) that were...     

渤海江豚组织中钠,钙,锶,镁,磷,钾的研究

１９９０年，作者于辽东湾采集了１０头江豚标本，分别测定了其骨骼、皮肤、肌肉、肝脏、肺、肾、心、胃、肠、胰、脾、肾上腺及生殖腺等１３种组织中Ｃａ、Ｓｒ、Ｍｇ、Ｐ、Ｋ、Ｎａ６种元素的含量，详细分析了骨骼及其他各组织中的Ｃａ／Ｍｇ值、Ｃａ／Ｋ值、Ｃａ／Ｐ值、Ｃａ／Ｎａ值和Ｃａ／Ｓｒ×１００值。结果表明，Ｃａ、Ｓｒ、Ｍｇ、Ｐ，Ｋ在骨骼中累积率最高，钾在肌肉中具有高累积，Ｓｒ、Ｃａ在肌肉中累积率最低；Ｍｇ累积率最低的组织是生殖腺，Ｐ累积率最低的组织是肠，而Ｋ在骨骼中，Ｎａ在肌肉中的累积率均高于其他组织。分析结果还显示，Ｃａ／Ｍｇ值最高的是骨骼，最低为肌肉，Ｃａ／Ｐ值最高的是骨骼，最低的是肌肉和胰脏，Ｃａ／Ｋ值最高为骨骼，最低为脾Ｃａ／Ｓｒ×１００值最高为肺、最低为肠，而Ｋ／Ｎａ值最高为肌肉，最低为骨骼，在骨中Ｃａ／Ｐ值大约为１，类同于猫和人类。

赣江流域山丘荒地的形成、危害和开发途径

赣江流域的山丘荒地总面积约为 2902×10⁴亩,除 35×10⁴亩属于“十边草地”零星分布于路边、河边、田边、村边、沟边之外,比较成片的约有 2867×10⁴亩（见表 1）,略多于现有耕地,而且相当于现有林地的一半。这些荒地 3/4以上分布在红壤丘陵（低丘岗地 388×10⁴亩,占13.5％;中低丘1236×10⁴亩,占43.1％;高丘605×10⁴亩,占21.2％;山地638×10⁴亩,占22.3％）,而且主要分于于上、中游地区（上游地区占60.2％,中游地区占25.4％,下游地区占14.4％）。综合开发治理、合理利用这些山丘荒地,是赣江流域、特别是上、中游地区的农民摆脱贫穷落后困境、实现小康目标的重要环节之一。

高速公路路线选择与地质灾害关系的研究

本文通过一条高速公路路线勘选的工程实例，研究了高速公路路线选择与地质灾害间的关系。认为，路线选择前，路线走廊及周围地区现时及未来地质灾害的勘查至关重要。这些灾害包括水库塌岸、洪水、断层和断裂带、滑坡、泥石流、崩塌等，路线选择应尽量避开这些灾害地区。对不能避开的地质灾害，应视其特征用不同方法治理，同时应兼顾工程造价、环保及行车舒适等情况。     

航空器场内失事应急演练评估指标体系与评估方法研究

针对目前我国民用运输机场航空器场内失事应急救援综合演练缺乏有效评估体系的现状，通过对演练过程进行系统分析，构建航空器场内失事应急救援演练评估指标体系，涵盖消防、医疗、公安、媒体应对、运行指挥中心、地服、飞行区7个组织部门的2级指标。结合航空器场内失事救援的业务特点以及指标体系内在逻辑，设计相应的评估方法，对开展的航空器场内失事应急演练进行评估；最后，以国内2个机场的相关应急演练过程为典型示例，进行应用分析。研究结果表明:构建的演练评估指标体系及评估方法能较好地应用于实际应急演练过程，进而在演练评估结果和建议的基础上，实现应急演练的持续改进。     

Fuzzy programming method for multi-objective optimal allocation of sediment resources and the cooperative bargaining: a case study in Weishan irrigation area,China

The optimal allocation of sediment resources needs to balance three objectives including ecological, economic, and social benefits so as to realize sustainable development of sediment resources. This study aims to apply fuzzy programming and bargaining approaches to solve the problem of optimal allocation of sediment resources. Firstly, Pareto-optimal solutions of multi-objective optimization were introduced, and the multi-objective optimal allocation model of sediment resources and fuzzy programming model was constructed. Then, from the perspective of multiplayer cooperation, the optimal allocation model of sediment resources was transformed into a game model by using Nash bargaining, and Nash bargaining solution was obtained as the optimal equilibrium strategy. Finally, the influence of different disagreement utility points and bargaining weights on the results was discussed, and the results of Nash bargaining and fuzzy programming methods were compared and analyzed. Results corroborate that Nash bargaining can achieve the cooperative optimization of multiple objectives with competitive relationship and obtain satisfactory scheme. Disagreement utility points and bargaining weights have a certain impact on the optimization results. The solution of fuzzy programming is close to that of Nash bargaining, which provides different ideas for multi-objective optimization problem.
