Research On Landscape Character Assessment And Conservation On The Second Phase Of Guangzhou Haizhu National Wetland Park

In recent years,with the rapid urbanization process in the pearl river delta region,the development at the expense of the environment has caused a great impact on the ecological environment and caused serious damage to the wetland landscape.The construction of ecological civilization provides a good opportunity for the construction of wetland park,but there are problems in the construction of wetland park,such as excessive gardening,homogenization,and loss of regional landscape characteristics.In order to avoid the homogenization of wetland park landscape,it is necessary to adopt specific landscape feature protection strategies to enhance the recognition of site landscape features and the construction of wetland park features.This study focused on the development of the current wetland park,through landscape feature recognition and evaluation,for the Second Phase of Guangzhou Haizhu Wetland Park(hereinafter referred to Haizhu wetland park phase ii)characteristics of landscape and landscape protection provide directional guidance strategy,also for landscape features protection perspective construction of wetland park landscape evaluation system to provide the reference and the further development of protection and wetland park landscape evaluation research in the field of use.In Haizhu wetland park phase ii study of this research field,the characteristics of wetland landscape elements and its type as the research object,the reference evaluation methods of landscape features of the process and system,establish a "theory-landscape feature classification defined-landscape feature identification and description-landscape features a comprehensive evaluation system-wetland landscape protection and use of guidance" research route,based on the characteristics of landscape protection perspective of Haizhu wetland park phase ii studies of wetland landscape.The research results are composed of the following three parts:The first part: relevant theoretical research and site analysis.At the beginning of the study,relevant concepts such as the classification method of wetland park were sorted out and analyzed,and the concept of the butt-base fruit forest wetland with regional characteristics in the second phase of Haizhu wetland park was defined.The second part is to review and summarize the domestic and foreign wetland park landscape evaluation and landscape feature evaluation method and other relevant literature,and put forward the applicability and reference process of landscape feature evaluation method to Haizhu wetland park phase ii,which provides reference and reference for the later construction of the landscape feature evaluation system of Haizhu wetland park phase ii.Finally,based on the analysis of the historical evolution and environmental characteristics of Haizhu wetland park phase ii,it is proposed that in the later stage of site development,natural and artificial forces should be coordinated,and natural characteristics,cultural characteristics,and biological characteristics of the site environment should be taken as the exploration direction to lay a foundation for the identification and landscape character assessment.The second part: wetland landscape characteristics classification identification and description.Through the definition of the scope,desktop research,site field research and interviews,the landscape feature identification and description were carried out under two scales of site and trench button-based wetland landscape.Firstly,five types of wetland landscape features were identified at the site scale,of which the ditch and button-based wetland was the dominant wetland landscape feature type.Second,under the drainage ditches groves scale,by topography,vegetation type,cover type,water,land texture form the combination of the common definition of landscape type area,consensus don't out of the 19 types of landscape characteristics and the characteristics of the formation of Haizhu wetland park phase ii partition map,among them,the traditional pile base fruit wood core landscape characteristics of wetland for the scales.The third part: construct the evaluation system of wetland park landscape features and put forward the strategies of landscape protection and utilization in different regions.Through the study of wetland landscape characteristics of Haizhu wetland park phase ii,indicators and evaluation methods were selected from the three dimensions of landscape attribute characteristics,visual characteristics,and biological characteristics to construct the evaluation system and select the corresponding evaluation method for the evaluation system of the trench pile-based wetland landscape of Haizhu wetland park phase ii.In,visual landscape,landscape feature attribute evaluation based on the results of environmental assessment and birds sensitivity evaluation,through the spatial overlay analysis,finally obtain the eight landscape management objectives and types of research area,and based on Haizhu wetland park phase ii development goals put forward eight zoning classification guidance strategy,landscape protection and utilization,to further guide the field landscape character development and reasonable protection and utilization to provide guidance strategy.
