Land Linear-landscape Ecological Design And Effect Evaluation In Coastal Area

The speeding up of urbanization makes the coastal area at the time of development, inorder to maximize the economic benefits, do not hesitate to change the original naturallandscape and has caused the deterioration of ecological system and the destruction of thenatural environment. So at the social background of paying more and more attention to theecological environment, according to the characteristics of the coastal area, using theoriginal cultural and social landscape to plan out the landscape to meet the needs of theecological regulation and economic development has very positive and practical value andresearch significance.This paper based on the theory of landscape ecology to coastal area, taking the linearlandscape which has an important place in the coastal area as the main research object,from the greenway theory, sustainable development theory and the perspective of theplanning theory to define the function of linear landscape. Furthermore, combining withthe characteristics of coastal areas, the linear landscape can be divided into three categories:type linear landscape road, river type linear landscape and coast liner landscape. Under theguidance of the design principles, constructing the linear landscape design system.Selecting the landscape pattern index, landscape stability index and landscape functionindex to evaluate the landscape ecological function before and after the design. TakeBeidaihe district tourism industrial development zone as an example of the empiricalresearch and put forward the related ecological protection measures of Beidaihe new area.Main conclusions:(1)Deepen the connotation of the coastal region linear landscape and divides the linearlandscape types.On the basis of the predecessors, try to introduce the concept of linear landscape toarea design, combine with the characteristics of coastal areas and deepen the connotationof linear landscape. According to the landscape elements of coastal regions, the linearlandscape is divided into three categories: roads type linear landscape, rivers type linear landscape and coastline type linear landscape.(2) Build up landscape design system of the coastal area linearBased on the principles of ecosystem integrity, adjust measures to local conditionsand ecology, present the design theory and method to the roads, trails in the roads typelinear landscape, the buffer width, connectivity of landscape and vegetation buffer width inthe river type linear landscape and coastline type linear landscape.(3) Establish the linear-landscape ecological effect evaluation index system of thecoastal areaEstablish the index system including landscape pattern index, landscape stabilityindex and landscape function index, calculate the landscape ecological function scorewhich after the design and analyze the differences under the condition of landscapeecological function.(4) Take Beidaihe district tourism industrial development zone as an example to carryout the empirical researchThrough the analysis of the advantages and disadvantages of the Beidaihe district, putforward the new macro, meso and micro linear landscape design plan, with Dapuhe townas an example for the specific design and evaluate the landscape ecological effects beforeand after the design. The results show that after design the landscape pattern, landscapestability and landscape function are improved, meets the realistic development needs andput forward the opinions and suggestions to ecological environment protection andimprovement of Beidaihe new area.
