Study On Zoning And Engineering Model Of Land Remediation Project In The Area Of Coalbed And Coal Hilly Area

The long river basin in jincheng of Shanxi province is a typical area of Loess Plateau landform types,Its own fragile ecological characteristics and habitat diversity,not only let the land use is vulnerable to natural?social?economic aspects of limiting factors,and unreasonable land use in the watershed environmental degradation caused by geological disasters the lack of water seriously restricts the sustainable development of local economy.Land reclamation is an important means to improve the land use structure,geological disaster,alleviate the shortage of water resources,ecological environment restoration,study how to carry out remediation engineering zoning and remediation engineering model for river basin area,has very important significance to carry out remediation project.This paper takes Shanxi city of Jincheng province river basin as the study area,mainly from the following aspects:(1)to carry out the research of domestic and foreign land remediation related research reviewed the introduction and review,to determine the basic research ideas in this paper.(2)on the basis of analyzing the restrictive factors of the land regulation project in the long river basin,the index system of the land reclamation project in the long river basin is constructed.Using the self-organizing double cluster method,according to the zoning index of the land improvement project of Chang River Basin,the plots of land patches are taken as the unit to cluster the plots,and finally the division results of the land reclamation project in the long river basin are obtained.(3)based on the zoning map of the land improvement project of the long river basin,combined with the restrictive factors of the project.The selected types of land consolidation works are rationally combined according to the main regulation targets in different regions,and the land consolidation engineering model in each regulation project area of long river basin is obtained.We can get the following conclusions:(1)based on the river basin land consolidation partition limiting factors,constructed by 5 first grade index limiting factors(topography limit,land destruction limit,farming level restrictions,social and economic constraints,vegetation,river basin hydrological limit)13 two indicators of the zoning index.(2)this paper adopts the spatial self-organizing double cluster method to divide the regulation project area.It not only reflects the consistency of the restriction degree in the region,but also takes care of the adjacency in the geographical position.The land reclamation project area not only has obvious regulation target,but also reflects the adjacent relation of the regulation goal in geography.(3)River basin land reclamation area the results can be found based on Land Reclamation District land remediation restrictive factors have a strong consistency,and the project area has very prominent target.The land consolidation engineering model established in this paper has strong pertinence.
