摘要
基于1973-2014年4期遥感影像数据,综合运用3S技术,分析阳朔县景观格局演变特征及与旅游业发展的关系。结果表明:1973-2014年阳朔县林地先减后增,农田和裸地先增后减,建设用地持续增加,水体和草地不断减少;旅游接待人次与建设用地、林地呈显著正相关,与农田、水体呈显著负相关;1973-2000年整体景观的破碎化程度增加,2000年后景观趋向集中连片,破碎化程度降低;从景观类型水平上看,林地优势景观的地位不断强化,连接度增加,农田破碎化加剧,趋向分散经营,建设用地复杂性增加,后期趋向于集中分布,水体和草地破碎化程度降低,复杂性减弱,裸地零散分布为主,破碎化降低、复杂性增加;1973-2000年景观变化主要受农林业种植活动以及城乡开发建设影响,2000-2014年受阳朔旅游产业大发展以及旅游城镇化影响,各景观类型主要向林地和建设用地转化。研究结果可为阳朔县景观格局优化调控和旅游可持续发展提供数据支持和科学参考。
Based on the four-period remote sensing images from 1973 to 2014,the characteristics of landscape pattern evolution and its relationship with tourism development in Yangshuo County of Guangxi Zhuang Autonomous Region were analyzed by means of 3S technology.The results showed that the woodland area decreased first and then increased,while the areas of farmland and bare land increased first and then decreased in Yangshuo County during 1973-2014.Meanwhile,the construction land area continuously increased,whereas water body and grassland areas changed on the contrary way.Tourist reception in Yangshuo County was positively correlated with construction land and woodland areas,and negatively correlated with farmland and water body areas.From 1973 to 2000,the fragmentation degree of the whole landscape increased,and after 2000,the whole landscape tended to be concentrated and contiguous,and the fragmentation degree of the whole landscape decreased.From the perspective of landscape type level,the dominant landscape position of woodland was strengthened and the connectivity was increased.Farmland s fragmentation was intensified and tended to be managed in a decentralized way.The construction land s complexity increased and tended to a centralized distribution in the later period.The fragmentation degrees and the complexities of water body and grassland decreased.Bare land was scattered distributed,with reduced fragmentation,and increased complexity.The landscape changes were mainly influenced by agricultural and forestry planting activities and urban and rural construction during 1973-2000.The landscape types were mainly converted to woodland and construction land due to the great development of tourism industry and urbanization in Yangshuo County during 2000-2014.The results could provide references for the regulation and optimization of landscape pattern and sustainable development of tourism in Yangshuo County.
