From 2019 to 2020, Fujian Province has carried out two rounds of provincial housing safety screening, with a certain data base.
After three years of hard work, the national housing construction and municipal facilities survey has been nearly completed.
The pilot area summarized the practical experience and proposed that the early office work is the basis of the “internal – external – internal” model.
The key is to make good use of the results of the housing safety inspection and rectification in the past three years, do a good job of data docking and review, and effectively improve the quality and efficiency of the census.
“One table” is the basic data table.
The national conditions and strength are the foundation of a stable state.
At the survey stage, we should “move as you see”, improve the quality of the survey work, and promote the survey progress.

According to Xiang Yong, deputy director of the Housing and Urban-Rural Development Bureau of Rizhao City, Shandong Province, Rizhao City pays attention to the “three words” of “full, true and teaching” in the field survey process.
The Ministry of Housing and Urban-Rural Development strengthened overall planning and coordination, fully mobilized all forces, and firmly grasped the direction of the pilot work.
It can be said that the field survey is the most critical link in the survey of housing construction and municipal facilities, and the quality of the survey is directly related to the quality of the survey data.
Before large-scale field survey, each district and county selects 2 to 3 representative village residential pilot sites to verify the feasibility of the plan, test the training effect, and take timely measures to correct the problems found, effectively avoiding the repetition of the work.
First, through reading the existing special survey results such as land (real estate) ownership confirmation, registration and certification of rural housing ownership, and the third national land transfer, and consulting the urban construction, planning and other archival data, extract the effective information such as house graphics, addresses, floors, areas, and structures, and form the basic data database; Then, on the basis of the system base map, integrate the existing data results such as mapping topographic map and land remote sensing image to optimize and improve; Finally, through the collection, analysis and interpretation of the basic data collected in the office work, the relevant information of housing facilities is extracted, and the basic data mapping table is formed.
“At the beginning, the villagers did not understand and cooperate with the census work, which made it difficult to promote the survey work.
Chongqing Municipal Commission of Housing and Urban-Rural Development has comprehensively applied the methods of “meeting coordination, letter invitation, meeting and consultation” to collect the existing office data from various aspects, and has organized professionals to analyze, compare and sort out the available data by using the first national geographical survey, the third national land survey, real estate registration data, dilapidated housing reconstruction and other special surveys, as well as the relevant data and information of property management.
This experience has been popularized and applied in many parts of the country.
The “one table” is a supplementary survey of the external industry, which not only realizes the rapid screening, extraction and utilization of the existing massive basic data collected from various industry departments, but also ensures the integrity of the basic data, improves the accuracy of the data, and speeds up the survey progress.
After we repeatedly stressed the importance and work content of the comprehensive risk survey of natural disasters, everyone’s initiative and enthusiasm to participate in the risk survey have been greatly improved.” Bao Liqun said.
It is not only necessary to verify whether the vector data of the house base map is accurate, but also to correct the inaccurate ones, delete the houses that exist in the system base map but do not exist, supplement the ones that actually exist but are missing in the base map, and also carry out on-site verification of the data information obtained from the initial office work, And supplement the missing information and data.
Jiang Jinming, member of the Party Leadership Group and deputy director of the Fujian Provincial Department of Housing and Urban-Rural Development, pointed out that the housing inspection in Fujian Province started early.
It has a large base and a wide range of fields…
unprecedented challenges and pressures.
Bao Liqun, Engineering Quality and Safety Supervision Division of the Housing and Urban-Rural Development Department of the Inner Mongolia Autonomous Region, added that the professional level of investigators, the degree of cooperation of villagers (neighborhood committees), the weather or environmental impact, and the normal operation of software are also important factors affecting the field survey.
All means that the investigation should be comprehensive, check and fill in the gaps one by one against the base map and the current situation; Truth means that the data should be true, based on facts, and cannot be “crowned with pride”, let alone fabricated; Teaching is to “model first”.
Taking Lanshan District, Rizhao City, Shandong Province, and Fangshan District, Beijing City, as the pilot areas, it summarized and refined the “inside-out inside-in” investigation model, which laid a solid foundation for the successful completion of the investigation of housing construction and municipal facilities, and the comprehensive understanding of the “family background” of housing construction and municipal facilities.
In order to ensure the professionalism of the investigators, the Department of Housing and Urban-Rural Development of the Inner Mongolia Autonomous Region produced the census manual, shot the software operation video, and conducted on-site one-to-one practical guidance to provide security for the field survey..
The national comprehensive risk survey of natural disasters is a major survey of national conditions and national strength, and is the basic work to improve the capacity of natural disaster prevention and control.
“One table” refers to the collection of existing basic data “internal – external – internal”, which means the integration of basic data collection (internal), field field mapping (external), and census results verification (internal) on the basis of data sharing.
Field survey is an important part of verifying the existing data of the office and supplementing and improving the missing information.
Make full use of the existing data and establish a “one table”, which not only facilitates the grass-roots personnel to get familiar with the survey system, but also consolidates the basic database, providing a solid guarantee for the smooth implementation of the risk survey work.
The Tianjin Municipal Commission of Housing and Urban-Rural Development urged the districts to exert their subjective initiative before the survey began, coordinate the data of all parties, and fully prepare for the office work.
The survey of housing construction and municipal facilities, as an important part of the survey, takes up 98% of the total census data.
It is necessary to collect and sort out the existing data results of various industry departments, comprehensively check and sort out the existing data of the department and relevant departments, and do a good job of “one table”.
“Full, true and accurate” ensures the quality of field survey.
