Research on intelligent arrangement of soil sampling points in a geochemical survey of land quality
摘要
Abstract
The realization of informatization in the whole process of geological survey is the main direction of the develop-ment of geological survey.In the land quality geochemical survey,the arrangement of soil sampling points is much work,and how to efficiently and reasonably complete the arrangement of sampling points is the premise and key to the orderly develop-ment of field investigation.According to the relevant land quality geochemical survey specifications and based on the MapGIS platform,this paper realizes the automatic and intelligent arrangement of soil points under different work scales in the land quality geochemical survey,which mainly includes:①The preliminary layout and automatic numbering of soil double-layer sampling points in 1∶250 000 land quality geochemical survey;②The automatic layout of soil sampling points for 1∶50 000 land quality geochemical survey was realized under different average density requirements,and the layout results took into ac-count spatial uniformity and rationality;③Based on the K-means algorithm,the automatic point layout of differentiated sam-pling density of different land use types in the land parcel scale geochemical survey was realized,and the distribution of points within a single irregular block was uniform.Through comparison and verification,the automatic point layout method adopted in this paper can better meet the requirements of the relevant specifications and significantly reduce the work burden of technical personnel.关键词
