Immigrant settling for many years may be so strongly influenced by local culture that we cannot tell their descendants apart easily from natives, according to some characteristic of social behav-ior and folk customs. But some residual ingredients of spoken language and basic vocabulary former im-migrant often used have been inherited and still have been using today, which can help us trace back the im migrant's descent and get to know the laws of spreading and diffusion of culture. As a latish cul-ture- developed island far away from mainland, its culture of Hainan Island have strong outer language-orientated peculiarity. That is, the culture of Hainan Island is a kind of distinct cultural that integrated highly, which is on the basis of a native background culture called as "li culture", took in a lot of nut-ritive value from mamy other peculiar culture, such as "han culture", "miao culture", "zhuang cul-ture", " hui culture", and modern culture developed by overseas Chinese, agricultural reclai mation cul-ture, western culture etc. as well. In this paper, we can know that Hainan Culture is one kind of frontier pioneering cultures which is a outcome of Hainan's peroidic developments. And we find out the truth that the present Hainan dialects result from the continuous spreading and diffusion of frontier pi-oneering cultures in the couse of Hainan development, by aalyzing the peculiarity and distribution of Hainan dialects, and by studying spreading and diffusion of Hainan culture, by tracing out the devel-opment and evolution of Hainan culture. All these help us analyses the function of verification to the spreading and diffusion of frontier pioneering culture by dialect. That is to say, practicality of a special kind of culture and its propaganda often have decisive influence on cultural spreading and inheritance. These dialects emerging in a place become popular regionally and a distinctly directive sign, which is enough to deafly indicate characterisics of im migrant activity. Dialect is a mirror of im migrant history and the latter is a source of dialect. We can sort out clear line of transplantation and evolution and forming of Hainan dialects, on the basis of studying the dialect family-tree, which help us understand the interrelationship between immigration in the course of developing frontier areas and current dia-lects.

三峡旅游空间的拓展将形成大三峡旅游经济圈。此范围内的区域如何抓住机遇与三峡旅游内涵扩充接轨、更有效地发展本地旅游业成为这些地区所面临的共同问题。湖北恩施地区在原来三峡旅游区域中是一个旅游弱势地区，旅游产业发展相对滞后，在三峡旅游空间拓展的大环境影响下。有望成为三峡旅游腹地的旅游中心之一，对恩施旅游在湖北和三峡旅游发展大格局中的定位及其旅游吸引力进行了分析。探讨了恩施旅游的吸引体系及旅游业发展面临的主要问题及其相应的解决措施。

区域旅游联动开发是指在一定的地域范围内，各旅游地打破行政区划界限，根据旅游资源的内在关联性、地理空间的邻近性、旅游产品的互补性，进行区域间的联合与协作以区域旅游整体的力量参与竞争，进而实现各旅游地共同发展的开发过程。区域联动开发理论实质上是针对旅游欠发达、资源类似、竞争优势不突出的地区，在核心边缘理论和产业集聚理论基础上提出的一种区域旅游合作开发理论。笔者以川黔渝三角旅游区为研究对象，分析这一区域进行区域旅游联动开发的必要性和可能性，指出只有通过区域旅游联动开发才能实现区域内各景区的持续发展。
