چکیده

Abstract The current study investigated the impact of coal mining on deep soil moisture from perspective absolute value moisture. A combined classical statistics and multi-dimensional geo-statistics approach was employed to analyze temporal spatial changes in 0 10 m face Nalin River No. 2 Mine Northwest China variability. results show that compared with control area, average 1- 2-year subsidence areas decreased by 1.18% 0.96%, respectively, whereas coefficient variation increased 17.92% 3.63%, respectively. Interpolation distribution showed variability area less than areas, 1-year indicating increases degree decreases as enters stable period. These provide evidence for mechanism which affects Preferential flow caused surface cracks, texture, pore microstructure, other factors are primary drivers increase

Scaled spatial variability of soil moisture fields

[1] This study identifies soil moisture spatial variability patterns using measurements across different extents (i.e., field, watershed, and basin) and depths (i.e., from surface to root zone profile) from 18 different soil moisture field experiments. The spatial variability patterns are well represented by negative exponential functions between the mean and the coefficient of variation of soi...

Research on the Spatial Variability of Soil Moisture

China is a country seriously suffering from the lack of water resource, especially the north of China (a dense area) where there are more agricultural production than other places in China. Therefore, some have become most important problems which should be settled down right now for precision agriculture: saving the water of agriculture, optimizing the water for cropland as well as making use ...

Radioactivity level of soil around a coal-fired thermal power plant of northwest China

Background: The activity concentrations of natural radionuclides in soil around a coal-fired thermal power plant of northwest China were investigated for assessing the radioactivity level. Materials and Methods: Soil samples were collected around the coal-fired thermal power plant and their radioactivity levels were determined using gamma ray spectrometry. Radiation hazards were assessed by rad...
