Coastal protection forest is the main subject of coastal terrestrial ecosystems. The construction of landscape of coastal protection forest not only provide the productivity for the forestry resources and protect and maintain the ecological balance of forest landscape,but also form a special tourism resources. The construction of landscape forest won triple values——economic value, ecological value and aesthetic value, which brings the economic system into natural ecosystems harmonious, improving the ecological stability of coastal protection forest and landscape aesthetic value of coastal protection forest. To build the main biological corridor, urban ecological security barrier, landscape shelterbelts of ecological and cultural as a three-dimensional comprehensive protection forest. Response to the the call of"return to nature"from tourism industry people,the construction of landscape coastal protection forest should be designed some distinctive leisure, tourism landscape models to improve landscape beautiful degree of coastal protection forest, only in this way, can we maintain the ecological value of coastal protection forest landscape, add the economic value of value, enhance the aesthetic values, achieve the unity and optimization of ecological, economic and social benefits.This paper discussed the advantages of bamboo species as the coastal protection forest at the beginning, analysised the multiplicity of ornamental bamboo landscape, proposed the idea to build landscape protective bamboo forests in coastal sandy area. Based on the professional advice and the Analytic Hierarchy Process method, from the landscape effects and landscape quality, it formed an indicator system of evaluation for landscape protective bamboo forests in Coastal sandy area, which includes two layers, six layers of factors and twenty indicators, what is more, it has accomplished the construction of the evaluation system to calculate the weighing and combination weighing of the indicator.By the evaluation of four types of landscape protective bamboo forests at all levels------ mixed forest of bamboo in bare coastal sandy area, mixed forest of Pinus elliottii and bamboo, mixed forest of Casuarina equisetifoli and bamboo, pure bamboo in bare coastal sandy area ,the results showed that: the overall level of protective bamboo forests in coastal sandy area was middle, the level of landscape effects got a high mark, but the level of landscape quality was not so good, especially the level of the diversity of species, which need to be improved in better method. Mixed forest of bamboo in bare coastal sandy area had the highest mark in the four types of landscape protective bamboo forests, the second was pure bamboo in bare coastal sandy area,the mark of mixed forest of Pinus elliottii and bamboo was lowest in four types. we also analysised the reasons for the low level of types of landscape protective bamboo forests, provided a reference for the construction and optimization and gave a theoretical support for the future construction of landscape protective bamboo forests in coastal sandy area.
