- Abstract:
-
The authors make ecosystem restoration and reconstruction of degradation soil using theory of restoration ecology in the Three Gorges Reservoir Area.Soil ecosystem restoration and reconstruction technique measures are obvious under different land use types.We can adopt the technique of changing slope to terrace,farming and agriculture techniques and growing contour tillage of hedgerows to degraded sloping plantation.To degenerate woodland,we adopt measures such as improving forest renewal manner and planting technique,increasing fertilization devotion,developing mixed farming,taking solid planting patterns.To degenerate grassplot,we first rebuild the existing grass hill and grass slope;second plant water conservation grasses in the bare lands with soil and water loss,they should be contour farming.To degenerate wasteland we can use man-made measures to quicken the ecology renewing process in which redeveloping the pioneer community and the implantation and growth of complex community in generally;To degenerate building land,we usually adopt land arrangement and reclamation;the building lands which are difficult to be replanted,we should use recovery and redevelopment measures of degenerate wasteland.
