| Jinsha river watershed in the upper Yangtze river "a screen,the two wings,three groups" spatial pattern of radiation Led a new round of development opportunities,in rapid urbanization period,it will directly affect the regional landscape pattern change.Middle reaches shek kwu to guanyin rock section "a library 's" the tiger leaping gorge reservoir,tiger leaping gorge,the two families,liyuan,areva,Jin Anqiao,dragon mouth,pulling and guanyin rock hydropower station construction area rapid changes in the landscape pattern,reservoir resettlement area economic recovery,reconstruction and adapt to the social relations and the decrease of the biodiversity,and many other problems.Many domestic and foreign related literature on urban landscape pattern change,but the watershed landscape pattern change and the research of the development of the urban system is lacking.So,based on the middle reaches shek kwu to guanyin rock valley radiation of yulong county,ninglang county,guozi hill of huping county,three county in 2000,2005 and 2000 based on the vector data and grid data of data source,by the data of land use and landscape classification and ArcGIS,MapGIS and Earth image technology,analyzes the landscape pattern index and the change of the landscape elements patches in a certain period of time,Reveal the impact of urbanization on landscape pattern and opportunities of the development of urbanization,the development of the reservoir resettlement and the development of towns,seek new positioning in the urban development and opportunities.Regional landscape structure and landscape characteristic is the coordinated development of urban land use and urban system is the key to sustainable development.The development of the jinsha river basin in middle town can rely on shek kwu to guanyin rock channel tourist resources,is very important to the future spatial pattern optimization,through the analysis of the natural geographical conditions and the conditions of tourism resources,adjust measures to local conditions for local travel channel planning,in order to let the resettlement area towns have more opportunities for development.The structure of this paper is divided into the following sections:The first part introduces the research background,purpose and significance,the relevant research status and research methods and framework at home and abroad.The second part is on the middle reaches basin shek kwu to guanyin rock section of the research scope,the natural geographical conditions,social economic situation to carry on the detailed elaboration,through to the situation in the study area are systematically comb,it is the core of the thesis.The third part is the core part of the paper,it is to the specific analysis of the study area.Real landscape system with digital vector quantization(raster data or data)approach,comparative analysis,2000,2005 and 2010 middle jinsha river valley shek kwu to guanyin rock yu-long duan county,ninglang county,guozi hill of huping county of landscape pattern change and "a library 's" the construction of hydropower station for researches in its impact,and to investigate the tourism resources in the study area,analysis and evaluation,with the aid of our country shipping good momentum of development of tourism and optimize the integration of landscape pattern in the future,planning middle reaches shek kwu to guanyin rock channel are put forward.The fourth part is the conclusion part of the paper,based on the above analysis,we learn that from 2000 to 2000 because of a library 's construction of hydropower station near the basin landscape pattern has certain influence,reservoir resettlement as well as immigration how to build a new town,finally put forward opinions.New town construction to speed up the reservoir immigrants,combing the full text research ideas And content,put forward the research and innovation of the paper,looking to the future research trend,provide advice for future continue to study. |
