The results indicate that the average concentration of PM_(10) and PM_(2.5) is 505.364 μg/m~3, 261.878 μg/m~3.The horizontal and vertical distribution of PM_(10) had a significant reduction with distance, but PM_(2.5) was not significant.
Total microbial numbers in 0～10 cm was more than that in the other soil layers, the vertical distribution of total microbial number was: 0～10 cm > 10～20 cm>20～30 cm>30～40 cm>40～50 cm, which decreased along with soil depths.
The vertical distributions of 210Pb activity appear two-segment models regularly in the fine-grained sediment areas of the Yellow and Bohai seas characterized by high 210Pb activities and low sedimentation rates, reflecting that the sedimentary environments in the fine-grained sediment areas are stable.
This study using single point method、horizontal profile method and vertical profile method measured concentration distribution of PM_(10) and PM_(2.5) concentrations distribution near major roadside in the Chongqing downtown area .
The rodents density in rubbish spots was highest((7.27%)) at outdoors in horizontal distribution and the rodents densities in ground((6.04%)) and over ground((5.48%)) were highest in perpendicular distribution.
This paper reports the perpendicular distribution of the rare and endangered endemic medicinal plants in Guizhou Province, including 33 species from middle and love middle-mountains, 19 species from middle-alpine and plateau, 18 speeies from hills.
Relation between Growth and Vertical Distribution of Fine Roots and Soil Density in the Weibei Loess Plateau
A model for vertical distribution of fine roots in Robinia pseudoacacia plantations on the Loess Plateau
The vertical distribution regions of Abies are from sea level to an elevation of 4,700 m, concentrated in 1,000-2,000 m (15 species).
Soil animals are abundant in forest litter layer, but little attention has been paid to the vertical distribution of community structure of soil animals in the layers at different plant community succession stages.
The results indicated that there was a distinctive vertical distribution of the soil animal communities in the forest litter layer, but it differed from that in soil below the litter layer.
The results show that most of the vertical distributions of plant roots belong to the type wherein the roots are concentrated in the topsoil layer (0-20 cm), far more than those in the lower soil layers.
Based on a detailed investigation of vertical distributions of fine roots in Robinia pseudoacacia plantations at the Ansai Soil and Water Conservation Station, Shaanxi Province, a model was developed for the deep distribution of fine roots of R.
Spatial and vertical distributions of extracellular enzymatic activity were established.
Thin-layer vertical distributions of purple sulfur bacteria in chemocline zones of meromictic lakes Shira and Shunet (Khakassia)
The surface and vertical distributions of radionuclides are studied.
For these zones the dependence of the width and the buoyancy integrated over the vertical profile on the radial distance is established.
Six zones, which have characteristic colors and consistencies and are composed of intermittent layers, have been identified along the vertical profile.
Inversion of the frequency residuals resulted in the first in situ measurements of the vertical profile of Jupiter's deep zonal winds.
The vertical profile of the total rate of radiative cooling displays two peaks.
The results of studying the vertical profile of wind velocity and the vortex-formation mechanism in the atmospheric layer immediately adjacent to the water surface under the condition of developing wind wave are considered.
