名山旅游资源在现代旅游发展中起着极其重要的作用,然而过去对名山旅游资源特征的研究更多的是考虑其综合性,造成游客对名山资源个性特征的认识模糊,影响了对名山旅游地的识别.从名山旅游地植物资源角度,探讨了名山旅游地的个性展示内容与方法,这是提高名山旅游地识别度的有益尝试. 相似文献

经济欠发达型旅游资源非优区的开发探讨——以山东省阳信县为例 总被引:1,自引:0,他引:1
经济欠发达型旅游资源非优区的旅游开发研究是现在旅游开发研究的一个新的视角。由于经济基础、区位条件、资源禀赋的限制,经济欠发达型旅游资源非优区的研究面临种种困难,目前对于此种类型的旅游资源非优区的研究也比较缺乏。以山东省阳信县为例,在对其发展现状分析的基础上,分析其可行性开发条件,并从开发战略和开发策略两个方面对该地区的旅游开发进行了探讨,这不仅对当地的旅游发展具有一定的实践意义,而且对其它同种类型的旅游地的发展也具有一定的借鉴意义。 相似文献

1烟台市旅游业发展现状与存在的问题1984年,烟台市被国家定为14个沿海开放城市之一,经济得到了飞速发展,旅游业也有了生机;但从横向比较来看,它不仅与邻近旅游业发达的青岛、大连存在着很大差距,且发展速度也落后于成海等小城市。究其原因,首先是由于烟台市旅游资源的总体开发差,旅游景点少,开发深度不够,旅游资源的优势与特色设充分发挥出来,未能扩大客源市场;其次是旅游宣传力度不够,未能通过对旅游的宣传,突出该旅游区的优势,扩大客流量和消费者的持续增长。2烟台市旅游业发展优势分析2.1旅游市场开发环境目前,旅游业竞… 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
