Study On Rural Road Environmental Improvement Planning In Qinba Mountain District Based On Ecological Restoration

Richard Forman,a famous scholar in the field of road ecology,said that "road systems and ecosystems are like two giants who wound and fight with each other." As it says,the road is inseparable from the surrounding environment during its growth.In recent years,the rural roads often ignore the ecology in the construction process,and the contradiction with the surrounding environment gradually deepens,and affects the rural regional ecological safety.How to regenerate the rural road in the original way of the countryside is not only an "opportunity",but also a "challenge" for us.The Qinba Mountains lie in central China.The long historical changes and special geographical location have nurtured a large number of rural roads.Under the background of rapid urbanization,rural roads originally rooted in regional ecology and cultural environment are gradually falling into convergence and alienation,which adds worse to the Qinba Mountains with fragile ecological environment.The rural roads in Shaanxi Province,using interdisciplinary analysis,theoretical analysis,geographic information system,landscape pattern index calculation and systematic analysis.The main research work of the paper has the following three parts: the first part,the connotation analysis.By combing and summarizing the relevant research of the scholars at home and abroad,the typical ecological road practice cases are summarized as the background and starting point of the rural road research.From the perspective of ecological restoration,the connotation of rural road environment is systematically constructed,and the research framework of road and environment is built.Among which,rural roads are divided into macro regional road network,Zhongtian village road network mode and micro rural road structure form,and the environment is divided into ecological environment and cultural environment.Part II,subject Studies.From the complex adaptive characteristics of regional road network,village and road network mode,rural road and road domain environment,the low-graded rural roads have a great influence on the regional ecological pattern.Different adaptive characteristics of(2)village road network fit with terrain,symbiosis with water system,compatible with buildings and embedding with agricultural land.(3)rural roads and residential life,public space,agricultural production and riverbank mountain forest adaptation characteristics.Part 3,regional strategy.Based on ecological restoration,(1)repairs the road ecological pattern from the macro region,the rural road network from the perspective of central view,and the rural road engineering from the micro perspective.(2)takes the landscape reconstruction as the appearance,and carries out the rural road greening,beautification and improvement.(3)takes cultural shaping as the connotation and carries out rural road cultural landscape design.Finally,suggestions and examples on the whole process of planning-design-construction-operation-management.The research provides systematic ideas and methods,research results and regional strategies for optimizing rural living environment,ensuring rural ecological security pattern and promoting rural revitalization and development.
