加强CEPA框架下的粤港澳海洋事业合作

海洋经济在粤、港、澳经济中具有十分重要的地位，港、澳回归以后，三地海洋事业合作的内在需求得到充分表达。CEPA破除地方贸易保护和改进贸易合作创造了新机遇。建议以8个重点领域的海洋合作作为CEPA扩展的内容。     

文化气根现象与新移民文学心态——兼论澳门新移民文学中的文化气根现象

一个新移民文艺家,即便是"扎根"澳门再久、再深,他们的作品也难以真正对澳门社会文化实现"零距离"的表现。由于文化认同与心理、情感认同产生的机制不同,移民文人对于异地文化元根的表现总会有些隔膜,他们表现的文化可以描述为文化气根——一种与深入到泥土内部的文化元根并不一样。文化气根既彰明较著又相当浅显,这是移民文学家普遍的创作现象,对于澳门新移民文学而言,这是它的部分特色。     

回归前夕看澳门旅游业及其可持续发展

Track analysis and storm surge investigation of 2017 Typhoon Hato: were the warning signals issued in Macau and Hong Kong timed appropriately?

ABSTRACT

This study investigates the storm surge caused by Typhoon Hato, which severely affected Macau, Hong Kong, and other coastal cities in China on 23 August 2017. A typhoon and storm surge coupling model demonstrated that the maximum storm surge height reached nearly 2.5?m along the coast of Macau, while that in Hong Kong was slightly below 2?m. Furthermore, a field survey of urban flooding revealed evidence of a 2.25-m inundation in downtown Macau and a 0.55-m inundation on Lantau Island, Hong Kong, which were likely exacerbated by a combination of storm surge, heavy rainfall, and surface water runoff over a complex hilly terrain. Significant wave overtopping and runup also occurred in beach and port areas. A typhoon track analysis confirmed that several comparably strong typhoons have followed similar ESE to WNW trajectories and made landfall in the Pearl River Delta in the last few decades. Although Hato was not the strongest of these storms, its forward speed of about 32.5?km/h was remarkably faster than those of other comparable typhoons. Higher levels of storm signal warnings were issued earlier in Hong Kong than in Macau, raising questions about the appropriate timing of warnings in these two nearby areas. Our analysis of the storm’s pattern suggests that both regions’ decisions regarding signal issuance could be considered reasonable or at least cannot be simply blamed, given the rapid motion and intensification of Hato and the associated economic risks at stake.     

非规则网格下二维浅水流动的数值模拟

建立了一种在非规则结构化网格上求解平面二维浅水流动的有限体积方法。通过采用地形在离散网格内双线性变化及离散网格界面间地形连续的地形逼近方法和应用可以有效处理间断问题的Roe格式来离散浅水方程中的对流项,并通过VanLeer提出的状态插值法提高格式精度。在计算原始变量在网格内的插值梯度时,采用最小二乘方法求变量的最优梯度代替差分计算梯度,从而可采用任意形状的不规则四边形网格离散计算域。计算实例表明,该方法能够计算间断问题并能够处理各种复杂流态的过渡,具有较好适应性和计算精度,能够满足不同实际问题的计算要求。     

MULTIPLE TIME SCALE ANALYSIS OF CLIMATE VARIATION IN MACAU DURING THE LAST 100 YEARS

The multiple time scale climate changes are studied and calculated with statistical analysis and wavelet transformation on the basis of daily series of observed data over the period 1901-2007 in Macau.The result shows that statistically significant oscillations with 2 to 5 years of period generally exist in the series of climate variables(e.g.annual mean surface air temperature and precipitation as well as evaporation etc.),but with obvious locality in time domain.The variation of annual mean surface air temperature has a quasi 60-year period.The phases of the 60-year variation approximately and consistently match that of Atlantic Multidecadal Oscillation(AMO).The oscillations of seasonal mean surface air temperature in summer and winter have the periods of quasi 30-year and quasi 60-year,respectively.These two periods of oscillations have statistically significant correlation with Pacific decadal oscillation(PDO) and AMO,individually.The multidecadal variations of the precipitation of the annually first flood period and annual evaporation are dominated by periods of quasi 30-year and quasi 50-year,respectively.     

作为旅游资源的澳门区博物馆开发

400多年的东西文化交汇，赋予澳门独特的文化资源，要展示其丰富的文化遗产，博物馆正是一个最好的宣传工具，它运用直观的展品和接近民众的语言，向当地市民和游客宣传其自身的文化和历史，成为保存文化的重要宝库，文章将澳门区博物馆作为旅游资源看待。通过文献检索和网络查询，运用博物馆学和旅游规划的一些理论，把区内12座博物馆分为历史，科学和艺术3类，归纳出区内博物馆的特色；立体历史书，文物建筑的博物馆化，动静结合的展陈方式，公共教育性质和人性关怀，从文化模式，建筑文化，历史文化名城以及旅游产业转型，展示文化，政府运行，延长旅游者逗留时间等方面论述博物馆在澳门区旅游业发展中的资源优势和行业优势。最后从5个层面提出相应的开发建议；人力资源，特色博物馆，区内资源，相关资源和展陈手段的科技化。     

澳门地区土层地震波速的测量结果

通过一系列野外及实验室试验,对澳门地区土层地震波速进行了初步测量,从初步的现场试验结果来看,浅层的地震波速受到堆填物料的影响颇大,变化显得较为宽广,随着深度的增加,由于天然土层较为均一,地震波速的变化亦见收窄,现场剪切波速数据与标准贯人试验（SPT）数据可见一定吻合性。而通过等向及异向固结的实验室试验,发现澳门海泥的剪切波速在同一平均有效应力而不同应力路径下大致相同,此外,比较野外及实验室试验结果,亦显示澳门海泥的剪切波速受土体天然结构影响不大。     

澳门土壤剪切波速的相关性分析

土壤的剪切波速(VS),是抗震设计的一个重要参数,但有关澳门土层的相关资料则十分稀少。研究的主要目的是根据近期野外测试的结果,探讨澳门土层的VS与标准贯入试验的打击锤数(N)的关系,并以简单之幂函数建立VS与N值的关系式。作为澳门轻轨交通系统之勘察计划,研究进行了五组下孔法(DH),地震波圆锥触探试验(S-CPT)以及标准贯入试验(SPT)的测试。根据试验结果所得的关系式估算剪切波速高于较澳门轻轨设计大纲的建议值,而使用另一有关澳门土层的数据库来验证新的关系式,亦可获得合理的决定系数。
