Research On The Landscape Promotion Of The Changjiang River In Qimeng County Based On Ecological Safety Assessment

As an important energy transportation corridor in the ecosystem,rivers are essential for maintaining regional ecological environment stability and building regional ecological patterns.Eco-environmental safety assessment as a more operational approach provides a more scientific and convenient analytical method for river landscape improvement to better guide river landscape improvement strategiesFirst of all,the article clarifies the related concepts of river landscape,sorts out the development of river landscape at home and abroad,and clarifies the trend of China's river landscape improvement strategy becoming more and more harmonious with human and natural environment,and proposes that the river landscape is upgraded from local nodes to the whole.The development trend of overall planning and the significance of ecological safety assessment for river landscape improvement,using multidisciplinary theory to evaluate the safety of ecological environment will help improve the efficiency of people's ecological balance,and provide data support and graphics for river landscape improvement strategies.Based on this,targeted implementation of river landscape improvement initiatives.Secondly,taking the Lijiang River in Qimen County,Anhui Province as the research object,the value of the natural resources of the Changjiang River was analyzed from the aspects of elevation,meteorology,soil and biology.The landscape resources of the Changjiang River were analyzed from the aspects of natural landscape,human landscape and modern artificial landscape.Value;analyzed the main pollution sources from the aspects of domestic pollution,agricultural pollution,industrial pollution and tourism pollution.It sums up the advantages of rich natural landscape and cultural diversity in the current situation of the Changjiang River.It is suggested that there is a shortage of water quality in the Minjiang River and the hidden dangers of river pollution.Third,the ecological security assessment is used to further analyze the ecological security of the Changjiang River Basin.The model analysis method and the analytic hierarchy process were used to evaluate the ecological function importance and ecological environment sensitivity of the Minjiang River.According to the analysis and evaluation of water conservation function,soil and water conservation function,biodiversity function and other natural factors,ecological factors and social factors,it is clear that the overall natural landscape structure of the Changjiang River Basin is stable,the ecosystem is stable,and local areas are affected by geological disasters.Human disturbance has a greater impact.Fourthly,based on the results of ecological security assessment in the Changjiang River Basin,it is clarified that the landscape of the Changjiang River is based on ecological protection,and proposes a zoning protection and classification promotion strategy.The zoning protection strategy proposes disaster prevention and water conservation forestry strategies for water conservation areas.To propose pollution prevention and fish protection strategies for river water ecological protection areas;to propose agricultural pollution prevention,disaster prevention and development of agricultural tourism strategies for agricultural and forestry ecological protection areas;to propose strict control of pollutants and increase ecological construction strategies for urban ecological areas.Finally,on the basis of the premise of ecological protection,combined with the zoning protection strategy,the floods and Dabei water with high ecological security,rich ecological functions and diverse landscape resources are used as the key points for the improvement of the landscape of the Changjiang River,and a classification promotion strategy is proposed.For the pastoral needs,we should combine the industrial characteristics to enhance the tea garden landscape and farmland landscape;the two sides of the Changjiang River set up a viewing platform for the combination of mountain and forest,create a forest node,and repair the mountain with a local mountain damage;the banks of the Changjiang River combine the town and river relationship to create a wetland.The park will repair the ecological revetment;the two sides of the Changjiang River combine the rural landscape with the rural status,improve the rural infrastructure,improve the rural living environment,and create rural nodes.
