Based on contrast of examination and analysis of four planting modes, the serious soil erosion problem of mulberry garden on steep slope can be settled preferably by putting interplanting mode of tea and mulberry in practice.

Due to the limitation of terrain and culture on construction of expressways in mountainous areas,it is common to lay out lines on abrupt slope.

This paper introduces credible computing methods for discharge of starting ski jump and ending ski jump according to several cases such as abrupt slope,slope,zero slop and diffuser connecting to the front of nose of weir,which are compared with practical projects.
