Article Synopsis
- The study investigates how different plant species, specifically Bothriochloa ischcemum (fibrous roots) and Artemisia vestita (tap roots), influence soil detachment rates under overland flow conditions on the Loess Plateau.
- It was observed that as plant density increased, the soil detachment rates decreased significantly, with Bothriochloa ischcemum proving to be more effective in reducing soil erosion compared to Artemisia vestita.
- The research establishes a mathematical relationship where soil detachment rate can be estimated using overland flow velocity, soil bulk density, and root length density, indicating the complex interactions between vegetation, soil, and hydrological factors.
[Characteristics and factors influencing organic carbon decomposition in sediment in check dams].
Ying Yong Sheng Tai Xue Bao
October 2022
More than 56000 check dams have been built in the Loess Plateau, which capture around 0.95 Pg of organic carbon and act as an important carbon sink. However, the decomposition mechanism of organic carbon in the sediment in these dams is still poorly understood, and thus it is difficult to quantify their role in terrestrial carbon cycling.

- The study looked at how soil erosion and land changes in Nangou watershed, China, are connected over 37 years.
- Using special tools, they found that growing more trees and crops helped reduce soil erosion a lot.
- The "Grain for Green" project was a big reason for the positive changes in the landscape and made the land healthier.
[Spatial variation and source identification of heavy metals in sediments in Shaanxi section of Weihe River, Northwest China.].
Ying Yong Sheng Tai Xue Bao
December 2020
In order to understand the spatial variation of heavy metals in Shaanxi section of Weihe River, the contents and sources of Cd, Co, Cu, Pb, Sb, As, Ni, Cr, Zn, Mn in sediments at 17 sampling sites in Shaanxi section of Weihe River and its tributaries were analyzed. The results showed that the average contents of Cd, Co, Cu, Pb, Sb, As, Ni, Cr, Zn, Mn were 0.10, 1.

We set up runoff plots on slopes which were not cultivated and were closed for many years in the Liudaogou catchment, a typical catchment in wind-water erosion crisscross region of the Loess Plateau. With artificial simulated rainfall experiments, the characteristics of runoff and sediment yield on slopes (10°, 20° and 30°) under different utilization intensity of vegetation were studied to select the reasonable utilization intensity.

This paper describes a series of simulated rainfall experiments which were conducted according to a randomized factorial design for five slope lengths (0.4, 0.

Article Synopsis
- * An artificial neural network (ANN) model was employed to optimize the conditions for immobilization, resulting in successful prediction of optimal parameters using a back-propagation design.
- * The immobilized cells maintained 83% of their activity under optimal conditions, demonstrating the effectiveness of the ANN approach for improving cell immobilization processes.
