4. Application in environmental science, hydrogeology, agriculture and forestry science and irrigation and water conservancy.
Application of Kriging Method in the Planning of Irrigation Test Station Network; The average daily water demand for many years is selected as the regionalized variable, and the optimal planning of irrigation test station network is selected (Zhang Ruijuan, 1989).
From the 1990s to the present, the application of geostatistics in agriculture is mainly in crop water demand, such as the spatial variability of crop water demand; Optimal estimation of crop water demand and optimal isoline map, etc.
Generally speaking, the applied geostatistics methods and techniques basically belong to the category of linear geostatistics, and other methods are rarely involved. In the application field, it is mainly used in the field of geology and mineral resources, such as geological exploration, mine development and reservoir description. In the field of production and application, there is still a certain gap compared with foreign countries
