A basic study on the social factors in the diversification of Ryuukyuuan dialects.

为动态掌握琉球方言多样化或变化的趋势，1996-1997年的调查从以下几个角度进行，重点是宫古群岛，这类调查很少报道。1)通过实地调查和邮寄调查平原市及其周边地区方言差异的实地调查1)1996年和1997年，对平原市男性土著居民对宫古方言、县政府使用的那霸方言和标准日语的形象进行了调查。通过将这一数据与1994年在那霸市同样收集的另一数据进行比较，很明显，宫古县的传统方言和标准方言之间产生的方言间从未巩固过那霸所观察到的独立地位，在那霸，方言间的地位已经如此确定，以至于人们将第三个变体命名为Uchinaayamatuguchi。2)在方言意识调查的同时，对宫古群岛，特别是宫古大陆北部方言、乌上美方言、卡里玛塔方言、伊科玛方言的多样化所导致的方言变异进行基础研究。这些方言的声音资料由DAT记录，质量较好，1988年作为本研究项目的报告之一出版了《龟形方言之声、词形和语法》（CD及其解释）。

To grasp the trend in the diversifications or changes in the Ryuukyuuan dialects dynamically, the investigation in 1996-1997 has been executed through the following points of view, focusing on Miyako archipelago where such survey has been hardly reported.1) survey on the dialect consciousness in Hirara city through the investigation by field research and mail2) survey on the dialectal variations observed in and around Hirara city by field resarchAs for 1), the investigation of images held by male native people dwelling in Hirara city against Miyako dialect, Naha dialect spoken in the city of prefectural government, and standard Japanese, was excuted in 1996 and 1997. By the comparison of this data with another data which was collected likewise in Naha city in 1994, it became evident that the interdialect generated between conventional dialect and standard in Miyako has never connsolidate such inndependent status as observed in Naha, where the interdialect have had so confirmed status that people has named the third variation as Uchinaayamatuguchi.As for 2), in parallel with the survey on dialectal consciousness, the basic research on the dialectal variations resulted from the ever-occurred diversification in Miyako arhipelago, especially in the northern dialects of Miyako mainland, Oogami, Karimata, Ikema. Sound data of these dialects was recorded by DAT with good quality, and The Sound of Oogami Dialect, wordform and grammar, with reference to Karimata Dialect (CD and its explanation) was published in 1988 as one of the reports by this research project.
