Most of the petroleum delivering pipe-line jetties running across wilderness are bare or grassless. In annual rainy season,precipitation washes heavily away pipe-line jetties' soil. It is one of the principle problemsof the normal operation. By lots of indoor and outside experiments,the formation of the bare pipe-line jetties and the mechanism of soil erosion are analyzed. Then a vegetation regeneration method for the light-mediated alkalized pipe-line jetties is put forward,and the feasibility of applying cement soil lining to the serious bare alkalized pipeline jetties is analyzed. The cost of construction is less than 1/5 of cement-rubble lining,so a new preventive measure is provided for the alkalized pipe-line jetties.
