| At present,my country’s urbanization process is developing rapidly.Due to the over-exploitation of mountain resources,the ecological environment has been irreparably damaged,causing natural disasters such as landslides,mudslides,and landslides.At the same time,the scarcity of green space for recreation in the city makes people yearn for the green forests in the suburbs.In the face of the continuous improvement of the level of human settlements,how to carry out ecological restoration of damaged mountains has become an urgent problem to be solved in urban development.Therefore,ecological restoration of damaged mountains is imperative.This research mainly focuses on the problems of instability of mountain structure,insufficient utilization of water resources,single vegetation structure,and lack of overall planning of landscape in the mountains of the Yellow River Basin in Zhengzhou City.,Landscape ecology and sponge city and other related theories and excellent cases,using methods such as research analysis,case study,quantitative analysis,design practice,etc.,from the perspective of ecological restoration,to conduct landscape ecological restoration research on damaged mountains.The ecological restoration strategy of damaged mountain is proposed under the interaction of the four elements of mountain,water,green and scenery,as follows:First,give priority to safety and ensure the stability of the mountain structure.The damaged area of the mountain is repaired according to angles of 0-30°,30-60°,and above 60°,and the near-natural community construction technology,the backfilling of the base cover,the method of cutting the slope and opening the platform,and the technology of hanging nets and spraying plants are used to ensure the foundation of the mountain.structural stability.Second,optimize the site and build an ecological sponge.Use the rainstorm intensity formula and the volume method to calculate the rainwater runoff in the site,and use the low-impact development facilities such as regulating and storage ponds,grass-planting ditch,dry stream,horizontal ditch,and vertical ditch to collect rainwater to the maximum extent,so as to achieve high water consumption and water conservation,etc.Target.Third,simulate and correct to build a near-natural community.Simulate the characteristics of zonal plants,improve the naturalness of forest plants,regularly investigate the naturalness and timely transform and update,and finally restore the plant community to a near-natural state.Fourth,develop rationally and adjust the relationship between man and land.Based on the AHP method,the weight values of 8 index layer factors of slope,elevation,surface cover type,slope aspect,vegetation coverage,water buffer,current road network,and potential catchment buffer were determined,and the ecological sensitivity of the mountain was analyzed by using GIS technology.According to the layout map,the distribution of five areas of extreme sensitivity,high sensitivity,moderate sensitivity,mild sensitivity,and insensitivity are obtained,which provides a basis for rational organization of the site and planning and design.In the landscape planning and design of Taohuayu in Xingyang City,four design strategies of mountain,water,green and scenery are applied,and the protection and stability of mountains,the organization and design of water bodies,the planning and construction of vegetation,and the division and development of landscape space are carried out.Improve the local environment.Actively promote the development of mountain ecological restoration and planning and design in China. |
