The Multifunctional Evaluation Of Artificial Beach Land Use In Shajing Port Qinzhou

The beach recreation has become an important way of relaxation and entertainment for modern urban residents.Beach is a key element of the development of coastal tourism.The beach receives a large number of tourists every year,which promotes the development of local accommodation,catering,sports and entertainment.Beach tourism is the material basis for the sustainable development of coastal areas and the potential driving force of tourism economic income.It is natural,social and environmental functions play a key role.Qinzhou shajing port beach belongs to artificial beach.The biggest difference between artificial beach and natural beach lies in the difference of the source of tidal beach(intertidal zone)sand and the action mechanism of scouring and silting.In this dissertation.A case study of artificial beach in shajing port Qinzhou,By analyzing the temporal and spatial variation characteristics of land use and changes of the artificial beach profile shapes,beach surface sediment granularity characteristic change,reveals the artificial beach sediment balance mechanism and trend of beach profile morphology changes: the beach under the continuous action of tidal power,beach slope from relatively steep linear form to slope is relatively gentle wave form transformation,while the latter on the beach is significant,Especially the lower part;Through comparative analysis of sampling data,it can be found that the average particle size of surface sediments of artificial beach is 1.98?,and the median particle size is 1.96?,Basically,It conforms to the material standards for Maintenance on the beach,which not only has the function of leisure tourism,but also is an excellent natural coastal protection.By dredging engineering increases the depth of the water,reduce loss,the bottom of the wave energy dissipation and to reinforce the wave power,In order to enhance the lifting capacity of the shallow water wave and the submarine sand particles toward the shore handling,send fine particulate matter to the offshore area,is advantageous to the near shore formed strong dynamic environment,reducing silt deposit,slow down the development process of mud.The formation,development and maintenance of artificial beach require a suitable offshore wave dynamic condition.Based on the analysis of the balance of scouring and silting of artificial beach and the change characteristics of beach profile in artificial beach of shajing port,From natural function,social function,environment function to construct the evaluation index system,using the entropy method to determine the index weight,the comprehensive evaluation of the artificial beach land use multi-function implementation rate in shajing port Qinzhou,The results show that the artificial beach land use natural function,social function,environment function implementation rate were 0.115,0.065,0.173,and the total function is 0.11.It can be seen that the total sustainable level of land use function of artificial beach in shajing port of Qinzhou is low sustainable development level,Among which the natural function,the social function and environmental function are in the low sustainable development level.It indicates that the integration and development of various functions in artificial beach land use of shajing port is uneven,that land has great potential for development and utilization,and that the total function of land use has great potential for development.So it is necessary to further promote the development of various functions to a higher level.Suggestions in shajing port Qinzhou of the artificial beach in the development of multifunctional land use,The land use potential should be further developed and excavated.At the same time,we should pay attention to the role of the natural function,regular detection of the beach dynamics,through the beach maintenance measures,as far as possible to create a dynamic environment suitable for the dynamic balance and stability of the beach and coastal morphology.Reaching the coordinated development of the three functions of natural function,social function,environment function,Finally,the goal of efficient utilization of artificial beach land in manhole port is realized.Promote the intensive use of regional land resources and the healthy and orderly development of the region to provide people with a harmonious and beautiful coastal tourism and leisure holy land.
