Description

Technical Field

[0002] Land survey is the activity of measuring, investigating and surveying the natural and economic conditions such as topography, land type, location, scope, area, value, etc. within towns and villages. Specifically, land survey is the surveying and mapping activities such as field investigation, measurement, analysis, evaluation and drawing of schematic diagrams of the natural and economic conditions of land in activities such as land development, land use planning, land consolidation, land expropriation and land transactions. Soil sampling refers to the activity of taking a certain number of samples from the soil for testing and analysis in order to understand the nature, characteristics and quality of the soil. Soil sampling is usually carried out in a certain area, and zoning sampling is carried out according to factors such as soil type, topography, and climatic conditions to obtain more accurate data. Soil sampling can be carried out mechanically or manually, and the depth, quantity, and distribution of sampling should be carefully designed and implemented according to different research purposes and requirements. Through soil sampling, we can understand the basic properties of the soil such as texture, structure, organic matter content, nutrient content, pH value, moisture content, etc., and we can also understand environmental quality indicators such as heavy metal content and number of microorganisms in the soil.
