Land Use Evolution and Its Impact Factors in Silver Beach of Beihai City
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.
