缅甸的平衡外交及其对中缅关系的影响

为了应对西方的制裁,缅甸选择了平衡外交,密切的中缅关系以及缅甸自身的优势也是促使缅甸实施平衡外交的因素。缅甸的平衡外交使中缅关系受到了一定程度的冲击,但从缅甸面临的国际形势和平衡外交的实施效果来看,中缅关系不会受到实质性的影响。而且,平衡外交的实施对中缅关系的健康发展还起到了一定的积极作用。     

Three more new species of Cyrtodactylus (Squamata: Gekkonidae) from the Salween Basin of eastern Myanmar underscore the urgent need for the conservation of karst habitats

An integrative phylogenetic taxonomic analysis recovers three additional new species of karst-associated Cyrtodactylus Gray (Squamata: Gekkonidae) – C. bayinnyiensis sp. nov., C. chaunghanakwaensis sp. nov. and C. naungkayaingensis sp. nov. – from a narrow zone in the Salween Basin of Kayin and Mon states in eastern Myanmar from which nine new species were recently described. This degree of unprecedented diversity and site-specific endemism will no doubt continue to rise when at least 44 unsurveyed karstic habitat-islands in this same area are also explored. These data indicate that karst habitats not only serve as foci for speciation, but their rugged terrain spares them from agricultural development and, as such, they are the only habitats in the Salween Basin wherein much of the pre-agricultural herpetofauna can survive. This continues to underscore the fact that karst habitats in Myanmar harbour a significant portion of that country’s herpetofauna, some of which remains undescribed. Despite eastern Myanmar constituting some of the most extensive karstic regions in South-east Asia, they are the least legally protected, with only 1% of their terrain recognised as vulnerable. Until karst habitats in Myanmar are thoroughly investigated, a significant portion of this country’s herpetological diversity will remain underestimated and unprotected. Therefore, issues associated with karst conservation and management in Myanmar should be elevated to a new level of urgency.     

火山活动影响下的碎屑岩地层对比方法及应用-以缅甸中央岛弧带为例

火山岩与碎屑岩成因机制不同,造就了两者的混积地层在对比过程中的穿时现象成为制约勘探的难点。以缅甸中央岛弧带为例,综合利用地震、测井、录井及分析化验等资料,探讨了火山活动影响下的碎屑岩地层对比方法。按照成因将地层划分为沉积旋回、火山旋回和混合旋回三类;并建立了不同成因旋回的对比原则和技术方法。最终将缅甸中央岛弧带五套地层划分为16个层组、44个层段。综合评价认为古新统Ⅲ、Ⅴ段沉积反旋回砂体较为发育,后期勘探中应重点关注。     

缅甸民族的种类和各民族现有人口

缅甸是东南亚民族情况最为复杂的国家之一。缅甸究竟有多少个民族,各民族现有人口状况如何,是一个一直没有弄清楚的问题。为此,在参考大量文献资料的基础上,对缅甸民族的种类和数量作了科学的分析、分类和厘正,并对当代缅甸各民族现有人口状况作了分析。     

印缅边界划分的历史回顾

在进行边界划分以前,印缅两国边界情况是由英国三次入侵缅甸最终形成的。1967年印缅签署边界协定,之后两国开始了陆上边界的勘界立碑和海上边界的划分。总的来看,印缅两国在边界问题上分歧很小,从而使边界划分得以顺利进行。印缅边界划分的背后,是印度从英国人那里继承了殖民时期占领的缅甸领土、缅甸为求得政权稳定而牺牲被非法占领的国土以及中国因素在其中发挥隐性作用。
