Spatio-temporal Differentiation and Driving Factors of Industrial Ecology of Restricted Development Zone from Adaptive Perspective: A Case Study of Shandong,China

Based on the adaptive analysis paradigm, this paper constructs an evaluation index system and an evaluation model of the level of industrial ecology of a restricted development zone from the perspective of the industrial system and of the environmental system, and studies the spatial-temporal differentiation characteristics and the driving factors of the level of industrial ecology of the restricted development zone of the Shandong Province, China, by using a variety of measurement methods. The results show that: 1) In the temporal dimension, the level of industrial ecology of the research area increased from 2005 to 2017, while in the regional dimension, it was higher in the eastern coastal areas, followed by the northwestern area and the southwestern area; 2) In the spatial dimension, from2005 to 2017 the level of industrial ecology of the research area had a clear spatial dependence, and the regional spatial agglomeration of the restricted development zones with similar industrial ecology levels become increasingly evident; 3) On the whole, the industrial ecology level in the study area had a clear spatial differentiation pattern, as it was higher in the north and in the east and lower in the south and in the west. Moreover, its evolution model changed from a ‘three-core driven model' to a ‘spatial scattered mosaic distribution model', and then to a ‘single-core driven model'; 4) Industrial ecology was positively correlated with economic development, foreign investment, science and technology, and negatively correlated with the government role, while industrial structure and environmental regulation failed to pass the statistical significance test.     

海陆过渡相地层有机质纳米孔成因及地质意义——以鄂尔多斯盆地东部山西组为例

海陆过渡相煤系地层已经发现丰富的非常规天然气资源。本文以鄂尔多斯盆地东部山西组煤系地层为例,通过开展微观特征分析及物理模拟实验,查明山西组主要孔隙类型为有机质孔隙、残余原生孔隙、不稳定矿物溶蚀孔、黏土矿物层间孔,认为黏土矿物层间孔和有机质纳米孔隙是页岩储集空间与常规砂岩储层的显著区别;山西组煤系地层广泛发育的有机质纳米孔,经过模拟实验认为形成于早期液态烃裂解气,随着原油沥青化,气泡被固化在沥青条带中形成纳米孔隙;集中发生在晚侏罗世至早白垩世末的异常热事件控制了裂解气生成的强度和范围,在此过程中沥青化产生的有机质纳米孔大幅度提高煤系地层非常规气储集空间和资源丰度。这一认识对于深入了解山西组煤系地层孔隙结构特征及非常规油气地质评价选区具有重要意义。     

大同盆地全新世以来孢粉特征和环境演变

通过对大同盆地东水头剖面孢粉植物群分析研究,揭示了全新世气候环境的演变特征.结果表明:全新世以来草本植物始终占据优势地位,落叶阔叶植物和针叶植物虽然有时在木本植物中出现高峰,但仍然未形成稳定的森林景观.该区植被类型是以疏林草原和草原植被为主,气候温暖偏干.全新世大暖期在8.5～4 kaB.P.间,气候不稳定,气候波动明显,与黄土高原地区具有良好的可比性.     

提升猎雷军士岗位胜任力的特情复现系统研究

猎雷是对抗智能引信水雷的重要方式,但受“战场环境、水雷情况、装备故障和装备运用”等因素的影响,猎雷效率较低。猎雷军士是执掌反水雷装备的第一人,提升猎雷军士的岗位核心胜任力对反水雷作战具有重要意义。围绕院校培养猎雷军士的现实需求,首先阐述了猎雷军士的岗位核心胜任力,并从特殊环境、潜在对手、装备特殊性能和特殊故障几个方面对猎雷特情进行了分析,在此基础上提出了基于模拟仿真技术加实际水域猎雷的特情复现训练方法。     

东大港水道流速垂线分布探讨

对辐射沙洲海域东大港水道4号站位连续2个潮次的流速测量资料进行了分析、研究,拟合给出了流速垂线分布关系,并根据实际测量资料率定了该站位各时刻6个水层的浑水水流的尾流函数项表达式,这些表达式表明浑水水流的尾流函数项是相对深度和摩阻速度的函数。     

酶解马氏珠母贝肉制备降血压肽工艺条件优化

以马氏珠母贝（Pinctada martensii）肉为原料,选用6种蛋白酶在各自适宜的条件下进行酶解,采用HPLC法分析酶解产物对血管肾张素转换酶（ACE）的抑制活性（IP）,筛选出碱性蛋白酶为其制备的最佳酶种类,并确定了水解度为21％时,产物具有较好的抑制活性。在此基础上,分别考察了加酶量,底物浓度,酶解温度及pH对水解度的影响。结果表明：当加酶量为0．175g／L,底物浓度为35g／L,温度为45℃,pH为9．5,水解时间240min为酶解最适宜工艺条件。通过SDS-聚丙烯酰胺凝胶电泳测定分子质量分布,表明酶解产物中主要为14．4ku以下的多肽分子。     

设计创意人才的空间集聚及其影响机理研究——基于城市舒适性视角

从城市舒适性理论出发,系统梳理了创意人才及其空间集聚过程的相关文献,构建了驱动中国设计创意人才空间集聚的城市舒适性指标体系,通过大数据方法从国内设计师社交平台站酷网获取设计创意人才的属性数据,运用地理集中指数、区位熵、负二项回归方法,深入剖析了中国设计创意人才的空间集聚特征与机理。研究表明:(1)中国设计创意人才及其创作在空间上呈现出显著的集聚现象,以北京为主的一线城市最为集中,但杭州、长沙、武汉、郑州这些新兴城市也表现良好,甚至超过部分一线城市;(2)城市舒适性理论在解释中国设计创意人才空间集聚时具有很强的解释力,其中文化环境、教育环境和自然环境是影响设计创意人才空间集聚的核心因素;(3)证实了西方创意阶层理论的部分结论,发现文化基础设施、文化遗产、文化旅游、高素质人力资本、温暖的气候与良好的空气质量是提升城市对创意人才吸引力的重要因子,同时发现科研投入对设计创意人才集聚具有明显挤出效应,并且西方学者普遍强调的生活环境舒适性因子对设计创意人才影响有限。为深入理解创意人才的空间过程及其影响机理提供了详实的实证案例,为地方政府改善城市创意环境提供了参考依据。     

Optimization of the OCO-2 Cloud Screening Algorithm and Evaluation against MODIS and TCCON Measurements over Land Surfaces in Europe and Japan

A method to tighten the cloud screening thresholds based on local conditions is used to provide more stringent schemes for Orbiting Carbon Observatory-2(OCO-2) cloud screening algorithms. Cloud screening strategies are essential to remove scenes with significant cloud and/or aerosol contamination from OCO-2 observations, which helps to save on the data processing cost and ensure high quality retrievals of the column-averaged CO₂ dry air mole fraction(XCO₂). Based on the rad...     

ONTOGENIC STUDY OF ISOZYMES IN GIANT TIGER PRAWN,PENAEUS MONODON (CRUSTACEA:DECAPODA)

The patterns of isozyme variation throughout the life cycle of the giant tiger prawn, Penaeusmonodon were described for ten enzyme systems (G3PD, MDH, LGG, GPI, MPI, FBP, PGM, LDH,PGD, and PROT). The zymograms showh little variation in the number of isozymic loci expressed duringlarval development compared with results reported for other penaeid prawns. There were specific ontogenicpatterns at some loci. As larvae developed beyond the embryonic stage, there was tendency for intensityof staining and complexity of banding patterns to increase.
