Analysis of Factors Influencing Farmland Soil Fertility The soil nutrient tester can help us to determine the soil nutrients and fertility in the farmland. Through determining the values ​​at different time periods, we can analyze which factors affect the soil nutrients and fertility, so as to regulate the fertility and maximize the maintenance of soil nutrients. The use of sustainability. The re-gionalized variable theory proposed by Matheron in the 1960s provided a theoretical framework for studying the spatial variability of soil and provided theories for spatial interpolation of soil, spatial structure analysis and optimal sampling design. basis. At present, the application of the principles and methods of geostatistics in soil science has become one of the main methods for quantifying soil spatial variability at home and abroad. In the past 40 years, scholars at home and abroad have applied this method to extensive research on the spatial variability of soil physics, chemistry and trace elements, reasonable sampling and spatial variability. In recent years, there have been many researches on desertification in Minqin. However, there are few studies on the spatial variability and influencing factors of soil nutrients for oasis farmland ecosystems under large temporal and spatial scales. Through field sampling, investigation and analysis, and data collection, this paper used geostatistical methods and geographic information system (GIS) techniques to study the spatial differentiation of soil nutrients in the Minqin County from 1980 to 2006, and analyzed the soil nutrients. The relationship between soil types, fertilizer inputs, and planting structure factors is intended to provide a theoretical basis for the future guidance of scientific management of soil nutrients and quality conservation of cultivated land in the Oasis area.
