With the development of a technique, global positioning system (GPS) has become progressively less expensive, lighter and easier to use. The accuracy of GPS has been improved and it appears applicable to the continuously monitoring morphology changes on the earth surface with small and slow change. The objective of this study is to use GPS to measure the morphology of gullies in a small catchment...
Accelerated soil erosion is thought to couple with population growth, land exploitation and environmental degradation, leading to a major pressure on sustainable development of agro-ecosystem. However, implementation of wise policy and application of sound new techniques combined with traditional knowledge, may lead to less soil erosion or limited erosion under the tolerable value while intensive...
Changes in the natural abundance of δ 13 C and δ 15 N in soil are proposed as indicators in the evolution of ecosystems caused by land management and/or vegetational succession. Such changes are seldom known due to the lack of comparative data on the levels of δ 13 C and δ 15 N in soils. To understand the distribution of C and N during revegetational succession, we...
The distribution and storage of soil organic carbon serve as basic data for the study of soil productivity, soil hydrological properties, and the balance among carbon-based greenhouse gases. In this study, the organic carbon storage and density distribution characteristics of the soil in the Zhifanggou catchment on the Loess Plateau were studied based on field investigations, laboratory measurement,...
Land use change has significant effects on soil properties and vegetation cover and thus probably affects soil detachment by overland flow. Few studies were conducted to evaluate the effect of restoration models on the soil detachment process in the Loess Plateau where a Grain for Green Project has been implemented in the past fourteen years. This study was performed to study the effects of vegetation...
Land use and its adjustment may greatly affect soil detachment process by overland flow via altering soil properties, root systems, and tillage operations, but few studies were performed to quantify their effects on soil detachment in the Loess Plateau. This study was conducted to investigate the potential effects of land use on soil detachment capacity by overland flow (D c , kgm −2 ...
Soil water is a key terrestrial water resource, particularly in arid and semi-arid regions of the world such as the Loess Plateau of China. Information on the dynamics of soil moisture following vegetation restoration is essential for managing water resources and can be helpful for adjusting relevant government policies. To evaluate the response of soil water storage (SWS) to long-term natural vegetation...
Soil erosion is a critical environmental problem of the Loess Plateau, China. As an important project for soil and water conservation in the semi-arid environment, the Grain-for-Green extensively transformed a wide range of farmland into vegetated land after the 1980s. Yet, the effects of vegetation restoration on soil erosion reduction are not well understood. In this study, we monitored runoff and...
Serious soil erosion across the Loess Plateau has decreased the concentration of soil nutrients to low levels. Biochar amendments to the soil are an efficient method of improving soil nutrients; however, the effects of biochar amendments on the different soil types in the Loess Plateau are not well understood. In our experiments, we compared the effects of biochar on the soil organic matter, nitrogen...
Soil water content (SWC) is a critical variable in studies of hydrological processes and the soil–plant–atmosphere continuum, especially in arid and semi-arid regions such as the Loess Plateau. Knowledge of the effects of vegetation types on soil water dynamics would aid in understanding the mechanisms responsible for water shortages and addressing the problem of poor long-term vegetation recovery...
Soil erosion is still a serious concern on the Loess Plateau of China. Cornstalk buffer strips are not commonly utilized for erosion control on the Loess Plateau, and there is little hydrodynamic understanding of this soil erosion control practice. A simulated rainfall experiment was designed to investigate how a cornstalk buffer strip affected soil erosion and to enhance the hydrodynamic understanding...
Increasing attention has been paid to the potential of croplands to mitigate rising atmospheric CO2 concentrations by adopting appropriate cultivation practices. Plastic film mulching with straw returning to promote crop yields is widely used in rainfed agriculture; however, information about the effect of this practice on carbon exchange is limited. Eddy covariance measurements were used to investigate...
Biological soil crusts (BSCs) are widespread in abandoned farmlands over the Loess Plateau after the “Grain for Green” project was implemented in 1999. However, few studies have been carried out to quantify the effects of BSCs on temporal variations of soil infiltration properties. This study was conducted to investigate the effects of two typical BSC (moss and cyanobacteria) on the temporal variations...
As the economy develops, infrastructure construction in the Loess Plateau of China often leads to the formation of exposed steep slopes over large areas. Exposed steep slopes will lead to severe soil erosion, which poses a threat to ecological security. In addition, the recovery of vegetation on steep slopes also faces significant difficulties. Therefore, research on the materials and techniques suitable...
Soil aggregate stability is essential for moderating the soil quality and preventing soil erosion. Vegetation restoration may effectively increase the stability of soil aggregates via soil organic matter. This study was designed to investigate the effects of vegetation types with long-term revegetation on the soil aggregate characteristics. Three vegetation type zones (grass land, forest-grass land...
A deeper understanding of the hydrological response to subsequent rains would be useful in the prediction of runoff production for planning vegetation restoration and assessing flood risks. We used subsequent rains to study the role of rain intensity and antecedent soil moisture content (ASMC) on runoff and erosion for coarse soil of the semiarid Loess Plateau in China. The study used a rain simulator...
