A research proposal for vegetation reconstruction in drawdown or water-level-fluctuating zone (WLFZ) of the Three-Gorge Reservoir, which was jointly put forward by researchers from the CAS Wuhan Botanical Garden (WBG) and the Chongqing Three-Gorge University, has recently passed the scrutiny of a panel of experts under the auspices of the Three-Gorge Project Office under the State Council.
As a unique phenomenon of reservoirs, the WLFZ refers to the shore zone between full and lower levels in a reservoir. After the accomplishment of the Three Gorges Dam Project, a 30-meter-high drawdown zone is anticipated along its both banks, covering an estimated area of 450 square kilometers.
The development of the greening technology for WLFZ is a key issue for the successful vegetation recovery in the region. As early as in the early stage of the Three-Gorge Project, WBG researchers made a research proposal and conducted a large amount of surveys and studies on the subject. In 2005, with the support of Three-Gorge Project Office, they joined hands with co-workers from the Chingqing Three-Gorge University in carrying out screening of floral varieties suitable for the zone. The research has scored significant results, and passed the acceptance check.
The new project is a follow-up study of the previous one. It features a set of clear-cut targets, decent contents and feasible technical routes, according the expert panel. Its enforcement is expected to help protect the bio-resources in the Zone, restore its ecological functions, and improve the local sceneries and ecological security of the reservoir.
