根据民族构成基本一致、具有相同或相似的语言、方言、类型和比较一致或相似的文化景观、文化地域分布基本相联成片、有一个反映区域文化特征的文化中心等五个指标，将海南岛划分为沿海文化区、临高文化区、儋州文化区、五指山黎苗文化区，又分合亩制和其他黎苗文化两个亚区，及三亚羊栏回族文化版块等五个文化区域

分析了海南岛地域文化的空间分布特点及其区域差异、南海岛文化景观的地理分异、人才及农业景观的区域分布等问题。指出海南岛地域文化的空间分布与地形条件和气候等地理要素密切相关，各种文化景观的分布总体上呈现沿海拔依次成圈层展布的特点：沿海平原地带城镇密布、人口众多、工业发展、交通设施齐备、整体文化水平处在最高层次、岛内丘陵、山地地区文化相对落后，另外，东部地区普遍先进于西部地区也是一个明显的特点。

提要本文针对干旱地区自然保护区的具体条件和特点，论述了自然保护区的建设和开发利用问题。指出干旱地区自然保护区的建设必须和开发利用协调起来，重视市场经济体制下自然保护区潜在的开发价值和多功能性。同时还要加强保护区建设和西部开发的联系，在国家发展战略向中西部倾斜的宏观政策调控下，努力探求干旱地区自然保护区和西部地区的共同发展和繁荣。

在界定海南文化是一种开疆文化的基础上，对其地域扩散与整合进行了研究。指出，开疆文化在海南岛的传播扩散有别于大陆文化传播中占主流的沿江河、沿平原扩散的模式，而呈现出以移民和传染方式为主，先西后东，先北后南按海拔从沿海向腹部五指山，从低到高渐次推延的文化传播特点，此外，海南文化的形成，实际上是各种形式的开疆文化在海南地域上的一种文化长期作用的结果，即是在黎族文化本底的基础上，经历史时期汉、苗、回等民族文化，以及近代华侨文化、农垦文化等多种文化长期影响，并经相互碰撞、彼此融合等错综复杂的相互作用后，在海南这一地域环境下整合生成的一种海岛文化。

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.
