Study On The Division And Model Of Ecological Protection And Restoration Project In Zunhua City

Since the implementation of the "one map" project of land spatial planning,the ecological restoration project of mountains,rivers,forests,fields,lakes and grasses,as the guide of national spatial development and the basis of development,protection and construction,has played a significant role in land consolidation.The ecological protection and restoration project is different from the previous land remediation,which is an important means to improve the land use structure,control geological disasters,alleviate the lack of water resources and restore the ecological environment.With the development of target orientation and different implementation of planning,the overall layout of ecological protection and restoration projects tends to be complex.In this study,the impact of restrictive factors on ecological protection and restoration was identified by analytic hierarchy process,and the relationship between topography,slope,land use type,soil and ecological protection and restoration of landscape,forest,lake and grass was determined.Cluster analysis and unsupervised classification were used to divide the ecological protection and restoration area of Zunhua City,and the project type area was determined by comparing the land space planning of the county.According to the topography and the dominant factors affecting the engineering mode,the engineering mode is finally determined.Through this study,we can provide reference for the future construction and development of Zunhua City,promote rural revitalization,and serve the ecological protection and restoration planning of landscape,forest,farmland,lake and grass in Zunhua city.The results are as follows.(1)Most of Zunhua city is in the range of moderate ecological sensitive areas,and the ecological environment problems are more prominent.Based on the analysis of the restrictive factors of ecological protection and restoration project zoning in Zunhua City,Zunhua city is divided into 5 types of project type area and 7 types of project model area by four types of restrictive factors(topography and geomorphology limit,slope limit,soil level limit and land use level).The plain type area is divided into alluvial plain water-saving irrigation model area and piedmont plain comprehensive treatment model area,the Shahe River basin type area is divided into Shahe River Basin gentle slope Hill desertification comprehensive treatment model area and Shahe River source water ecological restoration model area,and the Lihe River basin type area is divided into Lihe River Basin soil erosion control project model area,The southern region is divided into the model area of the restoration project of the earth rock mountain forest,and the eastern region is divided into the model area of the comprehensive management of the mine ecological environment and geological disasters.(2)In this study,a variety of clustering methods are used for comparison,which reflects the consistency of restrictive factors in the region,defines the ecological environment problems,makes the ecological protection and restoration objectives consistent in the geographical units,and makes the engineering model well applied.(3)According to the expected effect analysis,the implementation of ecological protection and restoration project zoning and engineering mode in Zunhua city can not only clarify the ecological environment problems of Zunhua City from a scientific point of view,but also construct ecological suitable and land intensive and economical engineering areas from the perspective of regional combination and geographical adjacency.The ecological protection and restoration project established in this way has strong pertinence.
