1. Land use and cover monitoring: monitoring the types, distribution and changes of land use, including cultivated land, woodland, grassland and wetland, as well as the areas and changes of different land cover types. Through land use and cover monitoring, the impact of land use patterns on soil erosion and ecological environment can be evaluated.
2. Soil erosion monitoring: monitoring the degree and speed of soil erosion, including wind erosion and water erosion. Through soil erosion monitoring, we can evaluate the soil erosion situation in different regions and provide the basis for taking corresponding prevention and control measures.
3. Water resources monitoring: monitoring the supply and demand of water resources, changes in water quality and quantity, etc. Through water resources monitoring, we can evaluate the rational utilization and management of water resources and provide data support for soil and water conservation and water resources management.
4. Vegetation coverage monitoring: monitoring indicators such as the type, distribution and coverage rate of vegetation, as well as the changing trend of vegetation. Vegetation coverage monitoring can evaluate the effect of soil and water conservation and ecological environment quality of vegetation.
5. Slope and river erosion monitoring: monitoring the erosion of slope and river, including slope erosion, slope toe erosion and river erosion. By monitoring the erosion of slopes and rivers, the erosion risk in different areas can be evaluated.
6. Biodiversity monitoring: monitoring the quantity, species and distribution of species, and evaluating the changing trend of biodiversity and the protection of biological resources. Through biodiversity monitoring, we can understand the stability and health of the ecosystem.
Pre-inspection method
1. investigation and monitoring: through personal contact and extensive understanding, fully grasp and master the basic methods of first-hand information on soil erosion and soil and water conservation of the project. Including data collection, comprehensive investigation, typical investigation, sampling investigation, inspection and so on.
2. Ground monitoring: a method of monitoring soil erosion and its prevention and control effect at the initial stage of production, construction and operation of development and construction projects by setting typical observation sections, observation points and observation datum points. Including setting up residential quarters, control stations, soil erosion observation fields, drilling and other methods.
