Study On Landscape Planning Strategies Of Marine Ranching

Marine ranching is a fishery mode that,based on the principle of Marine ecosystem,constructs or repairs sites needed by Marine organisms to reproduce,grow,rope bait or avoid enemies in specific sea areas through artificial reefs,proliferation and release,etc,so as to increase and conserve fishery resources,improve Marine ecological environment and realize sustainable utilization of fishery resources.In recent years,China's marine ranching has developed rapidly.Marine ranching not only plays a role in the proliferation and conservation of fishery resources,but also promotes the restoration of china's marine ecological environment.In addition,the role of marine ranching in improving the economic benefits of recreational fishery and tourism is increasingly attracting people's attention.However,due to the single development mode and type of marine ranching leisure fishery,there are few studies on the landscape construction of marine ranching,which cannot support the in-depth tourism of marine ranching.This study based on the theory of landscape ecology and marine ecology basic principle,combined with the marine ranching construction content and features,analysis of marine ranching landscape elements,with the examples of Zhelin Bay marine ranching demonstration area,the landscape spatial pattern of the landscape ecological classification and analysis,comprehensive discussion marine ranching landscape ecological planning principle and the basis of strategy,and on this basis to Zhelin Bay marine ranching landscape ecological planning strategy analysis and planning advice,so as to realize the marine ranching ecological,economic and social benefits of further ascension,for the next step will provide a scientific basis for marine ranching landscape development.With the continuous development of marine ranching construction in china,it not only increases and preserves fishery resources,but also restores marine ecological environment and improves the economic benefits of marine ranching leisure fishery and tourism.However,due to the monotonous development mode of marine ranchingleisure fishery,there are few studies on the deep tourism and ornamental landscape development of marine ranching.Based on the theory of landscape ecology and marine ecology basic principle,combined with the marine ranching construction content and its function,landscape elements analysis of marine ranching,demonstration area as a case to Zhelin bay marine ranching,the landscape spatial pattern of the landscape ecological classification and analysis,comprehensive research and discussion on Marine ranching principle and basis of landscape ecological planning strategy on the basis of this to Zhelin bay Marine ranching landscape ecological planning strategy analysis and planning advice,which will provide a scientific basis for Marine ranching landscape pattern development,stable marine ranching ecological,economic and social sustainable development.(1)Based on the landscape ecology theory and combined with comprehensive marine ranching construction content and function of the Marine ecology principle,landscape elements analysis of marine ranching,can be divided into:natural landscape elements,habitat landscape elements,artificial landscape elements,the humanities landscape elements,every landscape formed by the elements of marine ranching and discusses specific conditions and content.(2)Taking zhelin bay marine ranching as an example,this paper classifies the landscape ecology with the theory of landscape ecological classification,and divides it into three first-level landscapes: open landscape,architectural landscape and cultural landscape.Five landscape are: nature landscape,semi-natural landscape,coastal landscape,science and education,cultural landscape and marine culture landscape,and based on the detailed division 16 three-level landscape level and set up zhelin bay marine ranching landscape ecological classification system,application of spatial analysis technology made at all levels of landscape ecological classification diagram,discuss zhelin bay marine ranching landscape category distribution and application of ecological significance between various patches.(3)Based on the ecological classification of Zhelin bay marine pasture landscape,the landscape spatial structure was studied by landscape pattern analysis method.The basic characteristics and heterogeneity variation of each patch of Zhelin bay marine ranching were analyzed by landscape element characteristic index andlandscape heterogeneity index,and the composition characteristics and spatial allocation relationship of landscape pattern structure were discussed.The results show that the natural landscape patches are the largest in the open landscape,the semi-natural landscape patches are the largest in the whole landscape,the cage culture patches are the richest in the landscape types,the architectural landscape and cultural landscape patches are less,and the tourism and cultural resources need to be integrated with Zhelin bay marine ranching development and utilization.As a result of landscape heterogeneity,the fragmentation degree of natural landscape patches is the highest in the upper half,the impact of human activities on the landscape is greater,and the separation degree between scientific and educational cultural landscape and the overall landscape is greater,which reflects the poor connectivity of the landscape corridor in spatial pattern and affects the landscape planning effect.(4)The results of spatial pattern analysis of marine animal husbandry scene view in Zhelin bay were synthesized to provide scientific reference for ecological planning of marine animal husbandry scene view.According to the technical regulations of marine ranching Construction and the elements of ecological landscape planning,the principles and basis of ecological planning of marine pasture scene view are analyzed comprehensively.The different types of marine ranching scene view pattern maps are drawn according to the classification criteria of marine ranching.Strategic research and planning suggestions are made on the landscape ecological planning of Zhelin bay marine ranching through case analysis.Enhance the overall landscape and ornamental value of marine ranching,make full use of marine environmental resources and biological resources on the basis of marine ranching recreational fishery,and provide reference for the sustainable development of marine pasture ecology,economy and society.
