| 摘 要： | 以北海银滩两组沙坝—潟湖景观的旅游开发为例,基于1990,2000和2003年的遥感数据和GIS技术,研究旅游开发活动对沙坝—潟湖景观稳定性的影响。研究结果表明,1)目前沙坝(滩)用于旅游开发,人类活动作用下加速岸滩的蚀退和潟湖的淤积,使沙坝—潟湖景观体系走向衰退。2)人类活动作用下两组沙坝—潟湖景观呈同步变化,海岸景观生态过程与联系使得整体的演变效应明显扩大。3)旅游活动影响下的沙坝——潟湖景观格局的稳定性主要取决于旅游经济活动对沙坝——潟湖景观的合理利用。研究结果可为沙坝—潟湖景观和海滩旅游度假区的旅游开发及生态管理提供参考和借鉴。

| Abstract: | Based on the remote sensing data and GIS techniques,the impacts of tourism development activities on barrier-lagoon landscape were studied by taking two groups of barrier-lagoon landscapes of Beihai Yintan as an example.It is shown from the studyre- sults that 1)the tourism development activities in the barrier area have accelerated the retrogradation of shore bank and the siltation of lagoon to result in the degradation of barrier-lagoon landscape system;2)the two groups of barrier-lagoon landscapes varied synchronously,and the ecological processes and relations of coastal landscapes signifi- cantly extended the overall effects of ecological evolution;3)the stability of barrier-la- goon landscape pattern under the actions of tourism activities is dependent mainly on the reasonable utilization of barrier-lagoon landscape by the tourism economic activities. The study results can be used for reference in tourism development and ecological man- agement of barrier-lagoon landscape and beach holiday resort. |
