To effectively carry out soil and water conservation work and monitor soil erosion in Fujian Province, southeast of China, Universal Soil Loss Equation (USLE) model has been adopted. Landsat8 OLI images, combined with topographical data, soil data and rainfall data were used. Then the soil erosion modulus of Fujian Province was calculated quantitatively based on USLE and classified into different...
The root spatial distributions were observed at selected typical sample plots within the 5m, 10m and 16 m belt-space caragana -grass compound systems. The spatial distribution characteristics of roots volume in Caragana and grass compound model with different spacing was studied using digging method. The results showed out that the horizontal distribution characteristics of all roots was similar with...
As an ecological process, soil erosion which endangers human existence and development has been one of environmental problem around the world for a long time. Affected by various environmental factors, soil erosion risk has obvious spatial distributions. Taked the Zhu River small watershed of red eroded area of South China as an example, selected the five risk factors of rainfall erosion, terrain...
In recent years, the environment has deteriorated and the sandstorm has been serious around Beijing regions, so monitoring vegetation change in Beijing and Tianjin sandstorm source control area is very important. The vegetation change of Beijing and Tianjin sandstorm source control area in 2008 was studied using MOD13Q1 NDVI data. The results have shown that the low coverage vegetation mainly grew...
The study on the coupling relationship between the variation of soil erosion and geomorphological factors in watershed scale will contribute to the effectiveness of soil and water conservation. Based on soil erosion database, the topographic variations of soil erosion in watershed and the relationship between it with different geomorphologic factors were analyzed in the paper, with a case study of...
Taking the landslides in Enshi Autonomous Prefecture for Tujia & Miao Nationalities (abbr. Enshi) as the study object, using statistic data of land use patterns as primary data resource, combined with engineering analogy method and ground investigations to find out the characteristics of the spatial distribution of the landslides in Enshi (including landslides location, quantity and corresponding...
The soil erosion intensity and its spatial distribution of Mashezihe watershed located at Bin county in the typical gentle hilly black soil region of Northeast China were studied using the Surface Erosion Grading Indicator (SEGI) method and Universal Soil Loss Equation (USLE) model. Land cover types and vegetation cover fraction derived from the Advanced Land Observing Satellite (ALOS) remotely sensed...
In order to reduce the massive soil erosion and to ensure sustainable development, the Chinese central government planned revegetation measures to reduce these environmental problems-especially in the Loess Plateau. This revegetation process will not only result in less soil erosion in the coarse sandy hilly catchments (CSHC), but also less runoff due to increased evapotranspiration (ET). A water...
Soil & Water are the most important limiting factors in enhancing the agricultural production. Effective rainwater management is vital to increase and stabilize crop yields. The objective of the present study is to effectively conserve the soil & water by estimating the spatial distribution of runoff for the most probable rainfall events for the area and considering the structures/earth work...
