Water Erosion 2. 0000035502 00000 n 0000104015 00000 n The Rq value was generally higher in the heavily polluted area, and the roughness of the abaxial surface increased more than on the adaxial surface. The accumulation of soil and crop debris at the. Steps should be taken to curb this problem. 0000001874 00000 n Soil Erosion Reduction by Grain for Green Project in Desertification Areas of Northern China. 0000102808 00000 n • Re-vegetation / groundcover within project areas. Climate change versus land-use change—What affects the ecosystem services more in the forest-steppe ecotone? HYDROLOGY | Soil Erosion Control. Authors: Wenjun Wei. (3) Compared with the earliest 50 years, the subsequent 50 years exhibited lower soil erosion moduli and accumulation moduli. 0��`��V+0`A�=m l �} In this review the roles of green GGE&H reduction are summarized and its future potential is highlighted. The existing problems and challenges for the GTGP were analyzed, and put forward some recommendations to overcome their shortcomings and enhance their potential. research activity from the FRIEND/Nile project with existing soil erosion information from literature. The purpose of the GLCP is to increase crop production and reduce soil erosion to achieve ecological and agricultural sustainability. Trees act as barriers against many causes of soil erosion including raindrops and moving wind. upslope as a result of the head of the gully being continually undercut and collapsing. 0000066345 00000 n 0000100536 00000 n Soil erosion is the most serious precursor of soil degradation that comes with global implications. 0000095900 00000 n This study will help improve the dust resistance and retention efficiency of forest shelterbelt projects during dust storms. Soils information. <]>> Construction activities and large earth-moving projects accelerate erosion dramatically, mainly by exposing large areas of soil to rain and running water. 0000002570 00000 n Effects of Water Erosion 4. 0000066157 00000 n 0000035688 00000 n Bing Wang. For such a removal to occur it is necessary that soil particles are detached form the land surface and then transported. This matters significantly, because topsoil contains the highest amount of organic matter and is best suited for agricultural activities. About this page. Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. The fine soil is more susceptible to the agents of soil erosion hence can easily be moved. startxref Resources Soil erosion is a naturally occurring process that affects all landforms. Soil erosion is one of the most serious environmental and public health problems facing human society. and the influence of pollution intensity was assessed by studying trees growing under different pollution conditions. Environmental pollution will change the leaf surface microstructure and its ability to capture PM. construction projects over approximately 2.5 acres. Compared with a clean area, in a heavily polluted area, the stomatal index of the leaves decreased, stomata were occluded, the leaf wax layer was degraded, the leaf surface contained more particles, the surface texture of S. japonica and G. biloba leaves became irregular, the boundaries of the epidermal cells became more irregular, and the trichrome of S. japonica became thinner, longer, and harder. Helping North Coast landholders reduce soil erosion . Soil particles that are in transport or have been transported to new locations and deposited are called sediment. The loss of topsoil leads to reduced fertility, resulting in lower yields. lower end of this field is an indicator of sheet erosion. 0000102625 00000 n Terracing with retaining walls & edging. With the increase in leaf roughness, the amount of PM on the leaf surface increased. 0000099091 00000 n Following are some of the methods of soil erosion prevention: Plant trees on barren lands to limit erosion of soil.
