Technical Field

The invention relates to the field of geographic information data processing, in particular to a reservoir engineering construction land acquisition and material object statistics processing method based on a GIS.

Background

The problem of flooding of a large number of people, houses, auxiliary facilities and other physical objects is often involved in the reservoir construction process, physical objects such as the people, the houses, the auxiliary facilities and the like in the land acquisition range of the construction are surveyed and counted, land acquisition compensation investment is calculated, and the development of relocation of migrants is an essential content in engineering construction.

The conventional survey statistical processing method is to survey real objects such as population, houses, auxiliary facilities and the like one by one according to a land acquisition range determined by an engineering construction scheme and then classify and count the real objects. The method has the disadvantages that when the construction scheme at the early stage of the project changes or physical achievements such as population, houses, auxiliary facilities and the like need to be counted in different areas or different flooding water levels in the implementation process of relocation and placement, a large amount of manpower is consumed for reclassification counting; meanwhile, in the process of re-counting, the phenomenon that counting is impossible or data is omitted due to incomplete early-stage survey data exists, and the working efficiency is very low.

Therefore, the research and development of a GIS-based reservoir engineering construction land acquisition and material statistics processing method becomes an urgent and important work.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a reservoir engineering construction land acquisition and physical statistics processing method based on a GIS, which can quickly and accurately count physical attribute information of population, houses, auxiliary facilities and the like and can be modified along with scheme adjustment; meanwhile, related physical information can be extracted quickly and accurately in areas or water levels according to project progress requirements.

The purpose of the invention is realized by the following technical scheme: a GIS-based reservoir engineering construction land acquisition and material object statistics processing method is characterized by comprising the following steps of:

s1, determining the survey range of the population and the real object according to the engineering scheme;

s2, developing physical survey according to the survey range, sorting the physical survey, and marking the name of the householder to a dwg format file topographic map according to the position of the house;

s3, processing the dwg format file topographic map, deleting an irrelevant image layer, and reserving a user main name annotation image layer;

s4, importing the processed dwg format file topographic map into GIS software, converting the annotation characters into point files by using a data management tool and endowing the point files with attributes;

s5, importing the sorted population and physical results into GIS software and connecting the GIS software with the point files;

and S6, importing the point files after the construction land acquisition range and the connection attribute into a GIS software analysis tool, forming an intersection file by using an intersection function, and exporting the intersection file to form a final real result of the target area.

In the above technical solution, the real object includes, but is not limited to, a house and its affiliated facilities.

In the above technical solution, an administrative boundary is introduced in S4, and a physical result survey report is formed in a fixed template format according to at least the demographic details and the summary results of the population, the house and the affiliated facility.

In the technical scheme, the expropriation, removal and compensation investment is calculated at least according to population, houses and auxiliary facilities, and the planned arrangement mode and compensation standard.

In the above technical solution, the step S4 of establishing a relational database by importing the topographic map and the physical product into the GIS geographic information system, and extracting the relevant data product according to the engineering construction requirement.

The method has the advantages that related attribute information is marked by utilizing the position of the house on the topographic map, and physical achievements such as target area population, house and accessory facilities are counted by combining a GIS software data management tool, so that the problem that complicated classification counting needs to be carried out manually due to adjustment of a construction scheme or decomposition of the physical achievements is solved. The classification and statistics of physical achievements such as population, houses, subsidiary facilities and the like become simple, efficient and accurate; meanwhile, the compensation investment can be formed by utilizing the physical achievement to provide a basis for the scheme comparison and selection, and the standardized design achievement is achieved.
