Database construction method and server for environmentally sensitive areas based on gis system

Abstract

The invention discloses an environmental sensitive area database construction method based on a GIS system, and a server. The method is completed in the server, and comprises: obtaining environmental sensitive area thematic data and storing the data into a map table; distributing a unique ID for each environmental sensitive area in the map table, and correlating the environmental sensitive area thematic data with the IDs; according to the number of the environmental sensitive areas, diving the map table into map layer tables in the same number, each map layer table being related to one ID and corresponding to one environmental sensitive area, and finally establishing an environmental sensitive area database, each map layer table being stored with basic attribute information and geographical location information of the corresponding environmental sensitive areas, and after the data in each map layer table is called by a client, the data is used to display map information of the corresponding environmental sensitive area. The environmental sensitive area database constructed by the method contains real-time updates and expansions of environmental sensitive area distribution.

Description

technical field [0001] The invention belongs to the field of data processing of substation environment sensitive areas, in particular to a GIS system-based environment sensitive area database construction method and a server. Background technique [0002] With the development of my country's electric power industry, the capacity of the power grid is getting larger and larger, the distance of transmission is getting farther and farther, the voltage level of transmission lines is also increasing, and the construction scale of high-voltage substations and overhead transmission lines is constantly expanding. Coupled with the influence of social factors such as economic development and population growth, it has become a general trend for new power transmission and transformation projects to gradually approach densely populated areas. In recent years, many cities have carried out the reconstruction and expansion of the power supply network. Substations have gradually been built fr...

Problems solved by technology

[0003] In the stage of environmental impact assessment and design of power transmission and transformation projects, due to the lack of relevant data on the distribution of environmentally sensitive areas, in the process of site selection and construction of power transmission and transformation projects, the measures and management support measures adopted by some projects in terms of avoiding environmentally sensitive areas Insufficient; the environmental impact prediction technology of power transmission and transformation projects is not high in terms of automation and informatization, and cannot quickly, timely and accurately evaluate the impact of power transmission and transformation projects on environmentally sensitive points during the stage of site selection and route adjustment.
