According to the seven-year data of soil moisture location observation of soil moisture recorder, the temporal and spatial characteristics of soil moisture were quantitatively analyzed in the wasteland of northwestern Shanxi, aiming at understanding the characteristics of natural wasteland soil moisture, and this will provide scientific basis for regional environmental supervision and Vegetation construction. The analysis methods for soil moisture data of the entire Loess Plateau region are summarized to provide an analysis approach for lateral comparison of soil moisture location observation data to promote the further study of soil moisture research.
With the continuation of observation time and the accumulation of soil moisture data, it provides conditions for the quantitative analysis of long-term soil moisture observation data. The soil moisture was determined by a drying method (105°C). The growth period was measured from April to October every month on the 20th of each month. Each sample was repeated 3 times. The soil moisture recorder was measured 7 times a year for a total of 7 years. Measured with a simple rain gauge. According to the precipitation standard, they belong to the normal year, the dry year, the normal year, the hemisphere year, the special drought year, the drought year, and the special year. The depth of soil moisture measurement is 0~300cm, 11 levels.
The numerical tests conducted by soil moisture recorders showed that the soil water dynamics from 0 to 300 cm soil normal rainfall and its normal distribution can be divided into the following stages: soil water accumulation period in late summer and early autumn. In the range of 0~100cm, the water storage volume changed greatly, being 72.7±29.2mm (mean±standard deviation); 100~200cm, the amplitude was reduced (83.7±24.2mm); 200~300cm was relatively stable (93.1±15.4) (m), only in the special year, soil water storage can increase significantly.
The real reason why photovoltaic pile driver is called photovoltaic pile driver is that the main application place or working environment of this screw pile driver is to drill holes for photovoltaic piles and press piles for photovoltaic supports.
According to different working conditions and different working functions, it can be divided into auger drilling (drilling soil and sand), rock drilling (stone and rock), hydraulic hammer pile (sand geological precast piling).
Studying the relationship between soil moisture is the main research content of the Loess Plateau and an important theme for water and environmental restoration. Soil moisture recorders have made great progress in the study of soil moisture and soil moisture for positioning observations, and the research content has been unprecedentedly wide. From farmland, planting soil texture and grassland soil moisture dynamics, slopes, slope direction and the way of use to soil moisture The impact of research and development.
