During rainfall infiltration, it may occur that a large amount of of slope vegetation soil are lost in and come down, Collapse Accidents, and in arid season or in arid
Area then can cause the withered phenomenon of vegetation since water evaporation rate is much larger than rainwater supply；（3）Due to high steep rock slope
Vegetation is rely the soil depletion of growth, and when vegetation growth to certain phase, without new nutrient supply, the growth of vegetation is limited
System, therefore, the later stage need to be safeguarded, maintenance cost is high；（4）Non-cubic structure between plant biological bag/blanket upper and lower surface, if for height
Gradient slope, under long-term rainfall or gravity, growth substrate adhesive force not enough can be sagging in band, plant movement；（5）Even if
Vegetation growth, since degradable rack gradually scatters and disappears to the effective support function of slope vegetation, depends merely on vegetation to after certain phase
The hinge that twines of itself root system is difficult to be effective against strong wind brash and landslip with attachment, and high gradient slope is especially true.Vegetation is certainly
Body retains even difficulty, slope vegetation protection effect and causes anxiety naturally.
