| The investigation and evaluation of landscape resources is an important link in the planning and construction of Guangxi Border-Sea National Scenic Road.In view of this,this study summarizes the relevant theoretical research and practical cases of scenic road landscape at home and abroad.Taking the Daxin section of Guangxi Border-Sea National Scenic Road as an example,it investigates and analyzes the current situation of Daxin section of scenic road,establishes the landscape evaluation model of Guangxi Border-Sea National Scenic Road,and conducts empirical research on Daxin section of scenic path Research,summarize the existing problems and put forward the preliminary landscape planning strategy.The main research results are as follows:(1)The landscape elements of Daxin scenic road are divided into two main categories:natural landscape and human landscape,six sub categories including landscape,water landscape,urban and rural landscape,and 25 basic types.Based on the survey of 120 landscape resources in Daxin section,the characteristics of landscape resources in Daxin section are summarized as follows:the landscape resources are rich,the types are diverse,the combination of natural landscape and human landscape is high,the natural landscape of karst is beautiful,the history and culture of border areas are thick,the rural areas of Zhuang nationality are beautiful,and the national customs are rich.And from three aspects of elevation analysis,slope analysis and land cover,combined with the situation of landscape investigation,Daxin section of the scenic road is divided into four landscape sections:Valley peak cluster,valley waterfall,valley peak forest,rural garden.(2)The research establishes the three-level landscape evaluation model of Guangxi Border-Sea National Scenic Road,which includes four indexes in the comprehensive evaluation layer,18 indexes in the project evaluation layer and 17 indexes in the factor evaluation layer.(3)According to the established evaluation model,this paper makes an empirical study on the four landscape sections of Daxin scenic road.Using matter-element extension evaluation method for quantitative analysis,the evaluation grade of four landscape sections-valley waterfall landscape section is "excellent",valley peak forest landscape section,rural garden landscape section is "good",valley peak cluster landscape section is "medium".Aftercomprehensive analysis,the overall landscape evaluation grade of Daxin section of Guangxi border sea national scenic road is "good".(4)Based on the landscape investigation and evaluation of Daxin section of Guangxi border Sea National Scenic Road,this paper sums up five major problems in the current situation of Daxin section of scenic road landscape,which are insufficient excavation of scenic road landscape resources,inadequate protection measures of resources and environment,urban and rural landscape to be sorted out,lack of recreational service facilities along the line,and urgent overall planning of scenic road landscape.In view of the above problems,this paper puts forward seven suggestions:In-depth investigation and research,full excavation of scenic road landscape resources,systematic analysis and evaluation,accurate grasp of scenic road landscape value,strengthen resource protection,do a good job in the restoration of environmental landscape along the line,highlight the regional characteristics,strengthen the natural landscape and Zhuang style,build a beautiful countryside,sort out the urban and rural features along the line,improve service facilities,improve the reception service level of scenic road,scientific Planning and design to enhance the overall attraction of scenic road. |
