The work included a combination of GIS technology, adoption of the differentiation index D, and the multi-group differentiation-measure model D(m). The results provided a basis for the following conclusions: 1) From 1988 to 2012, the degree of differentiation of the rural residential land first decreased, and then increased. The general residential, commercial residential and garden-house land-types all showed declining trends, of which the garden-house type presented the most intense volatility. 2) The overall background of the traditional residential land type was gradually replaced by a new residential land type, and the total area of residential land increased year by year, significantly improving the overall residential conditions. The areas of the new residential land type showed growth, and were increasingly widely distributed in the coastal tourist resorts, transportation corridors, and scenic areas. 3) Government policy, social differentiation, market mechanisms, and individual choices(along with other factors) were mutually promoted, although still restrained. However, all of these factors interacted to constrain the developmental direction and the processes affecting tourism real estate in the Dalian Jinshitan Tourist Resort.展开更多

It explores the causes for and responses to the decline of Chinese coastal resorts. The data were collected through in-depth interviews with twelve local key information providers, and secondary information sources such as government archives, survey reports, and resort plans. It was found that the rise and fall of Chinese coastal resorts in the last three decades is closely linked to the transitional reform from a central planned economy to a market economy. Three stages of coastal tourism development were identified in a sequence of rapid growth, decline and redevelopment. It was government financial funds and high local government involvement that promoted the rapid expansion of coastal resorts during the 1980s. However, coastal resort decline occurred when transitional reform was intensified and deflationary policy executed af- ter 1992. Institutional failure is found to be the main reason of Chinese coastal resorts decline since the mid-1990s. The government-dominated pattern could not be sustained and should be restructured in forthcoming coastal tourism de- velopment in China. Revival strategies should emphasize enhancing market-oriented reform in the declining resorts on both suoolv and demand sides.展开更多

This economy utilizes the basic role of the market in disposing resources and achieving regional development and social progress. In this paper we studied the town of Yanqi, a valley resort that has developed tourism-based valley economy for several years in the mountainous area of Beijing. This research identifies the spatial differentiation of tourism-related economic, socio-cultural, and environmental impact and level of support for tourism according to the perception and attitude of residents of Yanqi. The research area was divided into three zones(i.e., core, transition, and peripheral)according to the standard proposed by Jaakson. The residents in all three zones showed a positive attitude toward the tourism industry, and the residents in the core zone had a stronger perception toward the impact of tourism. However, several items indicated the converse. Correlation analysis and analysis of variance were used to explore the correlative factors associated with the attitudes of residents toward the tourism industry. Results indicated major differences among the three zones. Multiple factors, including natural conditions, policies, scenic spots, dependence on the tourism industry, and external investment in the three zones resulted in the spatial differentiation of the perception and attitude of residents toward the impact of tourism.展开更多

Among them, with the exception of Loggerhead turtle （Caretta caretta）, four species have been being lay eggs on the beaches along the country. However, these populations have been strongly suffered by human activities for decades. The number of foraging and breeding Hawksbill and Leatherback sea turtles has dramatically decreased, and Olive Ridley turtle has almost disappeared on their traditional nesting beaches. Beside the reason of harvesting eggs and nesting turtles by catch or by purpose, the developments in coastal areas where sea turtles laying eggs such as in shrimp aquaculture, tourist resort and residential area developments etc., also contributed to this decline of sea turtles. Despite the fact that the recent raising awareness programs on protection and conservation of the sea turtle were very well done with the participation of many organizations and provinces, this important animals still face the risk of extinction in Vietnam.展开更多
