Abstract
Considering the conditions that TEDA used to be hungriness area without vegetation and without agriculture, forestry, livestock farming, etc. , to rely on, the new conception “allowable depth”, established in coastal area of TEDA with shallow groundwater and silt soft foundation, and the new techniques on water drainage by “shallow-dense type” underground level pipes were introduced. Technical constituent, advantage and implementation of the new techniques were discussed. From the view of sustainable development of afforestation ,technical measures for comprehensive tackling and control of the wilderness areas such as salt affected soils and their application in practice were introduced.
