Mangrove Landscape Evaluation And Optimization Based On Ecotourism Development Of Shuidong Bay

Mangrove is an important resource for the development of forest recreation and ecological tourism in coastal area of China,internationally recognized as the world’s most popular science education and tourism function of the natural landscape,our country of the mangrove nature reserve have proceed different degrees of mangrove ecological tourism development in Hong Kong,Shenzhen,Zhanjiang,Hainan and other places.How to develop and use the mangrove wetland scientifically is a problem that must be considered in the development of regional green economy.With Maoming city construction trends to the sea,Dianbai area is badly in need of creating a casual landscape with functions,ecological and aesthetic value in one place to alleviate the pressure of the existing urban park environment,perfecting the urban structure,the Shuidong bay mangrove conservation area as the background.Landscape evaluation is a fundamental work of landscape optimal design.Firstly this study adopted the SWOT analysis method to analyze ecological tourism strengths,weaknesses,opportunities and challenges for the Shuidong bay mangrove;Secondly,using analytic hierarchy process(AHP)to explore the important factors affecting the quality of mangrove forest landscape and the relationship between the mangrove quality and each factor and acquired the landscape comprehensive quality level;Thirdly,A mangrove plant nearby view evaluation model was established by scenic beauty estimation(SBE)and quantitative theory I from phytocoenosium level and individual level respectively;The last,using three structure parameters of Angle scale,ratio of stand size and minging degree to analysis and evaluation the landscape spatial structure of Shuidong bay mangrove.The main conclusions are as follows:(1)The SWOT analysis results showed that the mangrove wetland in Shuidong bay had significant advantages on the natural conditions and the geographic location in the development of ecotourism.However,it also has disadvantages of serious pollution,such as poor infrastructure and monotonous landscape.Ecotourism development of the mangrove wetland in Shuidong bay should catch the opportunity to construct ecological civilization,to overcome the contradiction between development and protection,to take effective management measures,and to construct an ecotourism area with powerful ecological service function.(2)The most important factors affecting landscape quality of mangrove wetland are Water Quality and Ecosystem Health Condition。The evaluation levels of the Choices of Plant Materials,Convenience of External Traffic,Air Quality,and Ecosystem Health Condition in Shuidong bay mangrove are “best”。 The comprehensive evaluation is 3.527 and the grade is “good”,which suggests that the landscape quality of the mangrove wetland in Shuidong Bay is good.the main factors affecting the mangrove plant community landscape were landscape basement,canopy line change,plant space and layer feeling。(3)The main factors affecting the mangrove plant individual landscape were trunk shape,branch and leaf thickness,leaf color and breathing root type。water as landscape basement,canopy line change obviously,half open space,and strong layer feeling make for increase the degree of mangrove plant community landscape beauty,and the bare tidal flat landscape basement,straight plant canopy line,closed space and the lack of layer feeling can bring a negative impact to mangrove plant community landscape aesthetic quality.2)people like bend trunk,thick branches and leaves,colored,cable shape breathing root of mangrove plant individual,they don’t like mangrove individual plants without stem,leaf sparse,dark green color,and with geniculate breathing root(4)Shuidong bay mangrove minging degree is not high,simple type,single physiognomy,should introduce foreign species,appropriate to increase the degree of mixed forest,accelerating forest succession.Mangrove forest management is not only to protect and restore on the number,they need more protection and optimization in forest structure and function,through the adjustment of the spatial structure change the tendency of system functional degradation,to ensure that the mangrove ecosystem health and sustainable development.It is the foundation for Shuidong bay mangrove to proceed landscape optimization work on the basis of the landscape evaluation of develop the ecological tourism.The study set start from the landscape evaluation survey,synthesize the evaluation results,put forward the landscape optimization strategy and measures of Shuidong bay mangrove,in order to provides the theory basis for build beautiful mangrove landscape and good ecological environment,guarantee healthy and stability of the landscape structure,and realize the powerful,sustainable use,productivity and efficient mangrove ecological landscape.
