Effects of riparian land use on water quality and fish communities in the headwater stream of the Taizi

Sen DING, Yuan ZHANG, Bin LIU, Weijing KONG, Wei MENG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5,   Pages 699-708 doi: 10.1007/s11783-013-0528-x

Abstract: Riparian land use remains one of the most significant impacts on stream ecosystems.This study focuses on the relationship between stream ecosystems and riparian land use in headwater regionsFour riparian land types including forest, grassland, farmland, and residential land were examined toFour land types along riparian of 3 km in length were evaluated at 25, 50, 100, 200 and 500 m widths,Although the riparian forest is important for maintaining habitat diversity and fish communities, the

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2,   Pages 279-287 doi: 10.1007/s11783-014-0667-8

Abstract: A riparian ecosystem is an ecological transition zone between a river channel and terrestrial ecosystemsRiparian ecosystems play a vital role in maintaining stream health and bank stabilization.The types of riparian vegetation have changed greatly because of human activities along the Wenyu RiverThis study examines the impact of riparian vegetation patterns on water pollution due to soil nutrientcropland, whereas a different trend was observed for the riparian grassland.

Buffer capacity of granular matter to impact of spherical projectile based on discrete element method

Ying YAN, Pengfei LI, Shunying JI

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 1,   Pages 50-54 doi: 10.1007/s11709-013-0186-x

Abstract: Granular matter possesses impact-absorbing property due to its energy dissipation character. To investigate the impact-absorbing capacity of granular matter, the discrete element method (DEM) is adopted to simulate the impact of a spherical projectile on to a granular bed. The dynamic responses of the projectile are obtained for both thin and thick granular bed. The penetration depth of the projectile and the first impact peak are investigated with different bed thicknesses and impact velocities. Determining a suitable bed thickness is crucial to the buffering effect of granular matter. The first impact peak is independent of bed thickness when the thickness is larger than the critical thickness.

Strategic Study of CAE 2010, Volume 12, Issue 2,   Pages 108-112

Abstract: the theory of prior using of new information,based on the research of already existed strengthening bufferoperators, some new strengthening buffer operators are established.The flaw that the existing strengthening buffer operators can,t fully use new information of the dataAn example simulation shows, compared with the existing strengthening buffer operators, the kind of newstrengthening buffer operators increases the forecast precision of GM(1,1) remarkably.

Restoring soil health to reduce irrigation demand and buffer the impacts of drought

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 339-346 doi: 10.15302/J-FASE-2020348

Abstract:

Irrigation consumes three quarters of global water withdrawals each year. Strategies are needed to reduce irrigation water use, including increasing the efficiency of transfer methods and field application. Comprehensive restoration of soil health, specifically through organic matter amendments, can substantially reduce irrigation demand and increase crop yield. A program to restore severely degraded and desertified soils by incorporating coarse woodchips into the soil successfully increased rainfall capture and elevated soil moisture for several weeks between rainfall events at both Ningxia, north-west China and North Dakota, USA. With addition of fertilizer, woodchip incorporation further increased growth of wheat and alfalfa. Comprehensive soil health assessment of remnant grasslands was used to develop target reference soil profiles by which to guide restoration efforts. Given that most agricultural soils are degraded to some degree, soil health restoration can provide a powerful strategy toward achieving global food and water security.
