With these salinity responses, along with broad tolerance to water levels, B. syzigachne has great potential as an early colonizing annual species for conditions predicted to occur in many of the in-pit reclamation designs.
This paper combined the Coal subsided area land reclamation planning, adapted coal subsided area land suitability evaluation, land structure optimization method, the evaluation method of combining cost and benefit impact factors quantitatively and qualitatively to research the design of land reclamation plan.
These measures include a sea reclamation plan, marine functional zoning, regional sea use planning, a plane design for sea reclamation, a control index of the sea area for projects, sea area use demonstration and environmental impact evaluations, as well as an examination and approval administration with the management philosophy of total amount control and intensive use.
In recent months, Beijing has undertaken a massive land reclamation project designed to increase the surface area of a number of contested shoals in the South China Sea and allow the construction of air fields and permanent military facilities.
Examples include research by Li et al. (1999) who designed a pre-reclamation plan for Liuqiao coal mine based on land damage analysis.
A greenhouse experiment was conducted to investigate performance of columns containing varying layers of topsoil and subsoil (silt loam) and Yellow River sediment (sand) as proxies for designing reclamation strategies for subsided land in eastern China.
The saturated hydraulic conductivity (Ks) is a key property in the design of reclamation soils, influencing key aspects of the water balance including infiltration and net percolation.
Although a new concrete-gravity design by Reclamation was tested to survive a magnitude 6.5 earthquake, it performed poorly under the 7.0 that the USGS had originally estimated.
Therefore, a good project design for cutslope reclamation should adequately consider local topoclimatic conditions.
Digital elevation modeling software offers an opportunity to incorporate geomorphic principles into topographic reconstruction at the design stage of reclamation.
