Technical Method And Application Of Land Remediation Planning Database In Prefecture-level City

At present,China's land remediation is undergoing profound changes,and the land remediation has been raised to guarantee the development of modern agriculture,protect the cultivated land and balance the land allocation of urban and rural areas.Land remediation planning is the key to the smooth implementation of land use plan and is the important basis for scientific guidance of land remediation.Land remediation planning database is an important part of land remediation planning,which can help to improve the information management of land resources.Therefore,synchronous do a good job in land reclamation planning database construction for scientific establishment and effective implementation of planning,promote the land remediation planning and management information construction,enhance the level of land and resources management is of great significance.Firstly,this article analyzes the construction flow of the database of land remediation planning in prefecture-level cities,and then discusses the main technical methods for database construction.Based on this,taking Weihai City as an example,it conducts a case study of land consolidation planning database construction,and then proposes The standard and method for reviewing database results.The main results of the paper are as follows:(1)This article proposes a design flow suitable for the land remediation database of prefecture-level cities by consulting the relevant literature materials for the construction of a large number of planning databases and combining with the actual situation in Weihai City.The database was designed and analyzed from four aspects: data structure,data content,data layering,and metadata structure.Practice has proved that the database flow and structure design clarify the context of database construction,improve data security and management efficiency,and can meet the actual operational needs of the Land and Resources Bureau.(2)Use a variety of database construction techniques to ensure data quality.Adopting GIS data conversion technology and planning base-period conversion technology ensure the accuracy of conversion of the current data to the planning data standard file format and the consistency of mutual conversion of different land type attributes;data dictionary production technology,cartographic synthesis technology,and projection conversion technology ensure the use of The smooth convergence of data at the two levels of cities and counties laid a good foundation for database construction.(3)Summarize the quality inspection process of a suitable city-level land remediation planning database,classify and analyze the causes of the typical data quality problems,and propose targeted solutions to improve the efficiency of database construction.Personnel have certain reference value.By controlling the Weihai city land remediation planning database construction project practice has proved that the proposed database construction method effectively solves the key technical problems exist in the process of building library,on the quality of the data at the same time improve the efficiency of the library,graphics,data,text consistent goal,for smooth implementation planning to lay the solid technical foundation.
