摘要
This study employs geographic information system software to explore the influences of elevation, slope, the river system, traffic arteries and the central development zone on the land-use changes in Shihai between 1995 and 2010. Data were drawn from statistics from the first two remote sensing investigations of land use in the town of Shihai in China's Xingwen Global Geopark and its digital elevation model data. An analysis of the relationships between changes in land use was performed using relevant models, including a comprehensive land-use dynamic degree model, a single land-use dynamic degree model and a comprehensive index model for the extent of land use. The results suggest that a combination of natural and human factors influenced the changes in Shihai's land use during the time from 1995 to 2010. First, elevation and slope exerted environmental resistance. Specifically, as elevation or slope increased, the extent of change in land use decreased, despite local policies that have reduced the extent of this resistance. Second, the river system influenced land use such that, as distance from the river increased, changes in land use decreased and then increased, suggesting that the river has a resistant as well as propulsive influence. Third, traffic arteries and the central development zone created an environmental motivation to the changes in Shihai's land use; specifically, the evolving tourism industry results in increasing numbers of tourist trails and roads and continually expanding Geopark services' infrastructure. Thus, relatively more dramatic changes are experienced in the Geopark's proximate land use than in its surroundings.
