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.
The Dabieshan District is a main ecological area with a function of soil and water conservation where seven large reservoirs and irrigation systems of the Pishihang are distributed.
In this small watershed of the eroded black soil region, the present soil and water conservation measures play an important role in controlling the soil loss.
The aim of this study is to develop an efficient and accurate post-processing technique for acquiring information of soil and water conservation engineering, on the Loess Plateau of China, using SPOT image with 2.5 m resolution.
Ever since 1989, our country has implemented "Yangtze River soil and water conservation" project, Till the end of 1996, altogether 25.8% of erosion area in Jialing River has been improved after large scale conservation has taken effect.
In this paper, based on a long-term monitoring of water cycle in the water and soil conservation forest stands of Pinus tabulaeformis and Robinia pseudoacacia, the soil moisture deficit is calculated.
In addition, with long-term monitoring of soil moisture in stands, the authors also give an appropriate managing density specifically for the water and soil conservation forests of P.
The total amount of the sediment production and its distribution generated by the model is very useful for water and soil conservation in the sandy and gritty area of the Loess Plateau.
Relationship and its ecological significance between plant species diversity and ecosystem function of soil conservation in semi-humid evergreen forests, Yunnan Province, China
In this paper, based on a long-term monitoring of water cycle in the water and soil conservation forest stands of Pinus tabulaeformis and Robinia pseudoacacia, the soil moisture deficit is calculated.
In addition, with long-term monitoring of soil moisture in stands, the authors also give an appropriate managing density specifically for the water and soil conservation forests of P.
Tile area of soil and water erosion in Shandong Province amounts to44300km~2, 79.3% of the total mountainous and hill regions in Shandong.Yi-Meng mountainous area is the most serious one ill Shandong Province.Mengyin County is a typical case, the average amount of erosion soil infarmland is 2.09m~3/mu/yr., resulting ill a reduction of 3mm from soil layer. Destruction of the natural vegetation cover is the main cause of soil andwater erosion. Other causes include reclamation, uncontrolled grazing,unreasonabl...
Sabina vulgaris is a good species for sand-stablization and soil conservation and for the establishment of protective shelterbelts in arid and semi-arid zones in .Northern China. The trial result of artificial growing and cutting of the seedlings of Sabina vulgaris is pre ented in the study. The difficult technical problem for cutting the species has been initially solved throughout the experiments.
Based on definite typical investigations, the economic values of protective benefit and direct benefit as effected by farmland shelterbelts,water and soil conservation shelterbelts,windbreaks and sandbreaks,as well as pastureland shelterbelt,which were planted from 1949 to 1981 in regions of North, Northwest and Northeast China, have been estimated. The sum of values amounts to 2500 million yuan (Ren minbi) per year.It is equal to 67 percent of the funds invested in planting these shelterbelts in the past 3...
