| 摘 要： | 目的]针对北海市银滩海岸近些年土地利用巨变、生态环境退化的现象,分析区域土地利用演变特征及其影响因子,为该区可持续开发与管理提供科学依据。方法]基于长时间序列Landsat遥感影像,采用土地利用动态度、转移矩阵、强度及多样性指数等指标分析北海银滩滨海区土地利用演变特征,并讨论土地利用变化的主要影响因子。结果]1979—2013年的35a间,银滩滨海区建设用地、人工湿地面积显著增加,并且主要是由耕地、林地转入而来,从而导致耕地和林地面积显著减少,草地、水域和滩涂面积增减变化幅度相对较小。区域土地利用综合程度先增大后减小,但开发强度却一直在增大;多样性指数在2000年年前较为稳定,之后显著下降。银滩滨海区土地利用演变主要受气温、台风、潮汐等气候因子和城市化、围垦、渔业、旅游业和规划管理等人类活动因子综合影响。结论]近35a来,银滩海岸土地利用类型趋向单一化,开发速率减小但开发强度增大,空间分布破碎化,区域生态系统脆弱性增强。研究时段内,人类活动因子影响比气候因子更显著,各驱动因子影响物理机制及其定量化贡献亟待进一步研究。

| Abstract: | Objective] In recent years, land use of silver beach of Beihai City had experienced great changes and the subsequent significant degradation of ecological environment. Therefore, the land use evolution and its impact factors were urgently needed to be understood to provide an importantly scientific reference for future sustainable development and management.Methods] The remote-sensing images of Landsat were adopted to analyze the land use evolution and to discuss its impact factors in silver beach of Beihai.Results] In the years of 1979-2013, the areas of construction land and artificial wetland were considerably increased and were mainly transformed from cultivated land and forest land. The areas of cultivated land and forest land were substantially reduced accordingly. The areas of grassland, water area and intertidal zone had no great variation. Land use intensity was consistently increased. Before 2000, land use was diversified and after that it markedly reduced. Driving forces of land use change include not only climatic factors as air temperature, typhoon and tide, but also human activity factors as urbanization, sea reclamation, fishing, tourism and planning management.Conclusion] During the past 35 years, the land use of silver beach of Beihai City presented trends of simplification, slowdown but intensified and fragmental developed evolution, which was coincided with the enhancement in vulnerability of regional ecosystem. It is urgently needed to probe the interacting mechanism among the above multiple factors and to quantify the respective contribution of them to land use evolution. |
