A Suitable Contour Planted Geotechnical Pattern for Middle and Steep Soil Slope in Water-level Fluctuation Zone of Three Gorges Reservoir
[Objective] To find a kind of ecological management technology that can be adopted to solve the ecological problem existed in the Three Gorges reservoir area. Some appropriate ecological management technologies were researched to provide some reference for the restoration of ecological environment in the three gorges reservoir area.[Methods] To improve the foundation stability in the middle and steep soil slope of ecosystem
measure of open circulation of the reinforced concrete frame was adopted. To strengthen the vegetation coverage and soil fertility in the water-level fluctuation zone
measure of contour planted areal greening and geo-cell planted vertical greening were conducted. To increase the biodiversity and landscape level in the water-level fluctuation zone
some suitable plant arrangements at different slope levels in the water-level fluctuation zone were carried out
including "tree-shrub-grass-vine" (177~170 m)
"shrub-grass-vine" (170~160 m) and "grass-vine" (160~145 m).[Results] The pattern helped to integrate the traditional concrete slope protection technology and modern ecological slope protection technology
and to integrate contour-planted areal greening and geo-cell planted vertical greening
is beneficial to gain high unity of biological measures and engineering measures
system stability and opening
vegetation coverage rate and landscape level.[Conclusion] The application of this pattern has reference value and application perspective for the ecological management in water level fluctuation zone of the Three Gorges reservoir to some extent.
