Ecological river park: tidal river channel restoration and algae bioreactor landscape treatment in Shenzhen Riverborder

Abstract

Wetland are valuable habitat in Hong Kong. These area have been threatened by

rapid urban development in Hong Kong for the past 50 years. Since they handover of

Hong Kong from the British ruling back to China, the frontier land have been left

untouched for many years. And this land is precious and shall be treated with care in

order to preserve the ecological valuable area for our future generation to enjoy.

The design thesis would response to issues concerning with drainage channel

design in the rural Man Kam To district and current ecological stream park/wetland

compensation mitigation in Hong Kong. A study area in Shenzhen River, near Man

Kam To Border Control Point is selected as demonstration site for drainage edge

treatment together with storm-water treatment to restore the natural edge of the area.

In addition, an algae bioreactor treatment design will be incorporated as a vision to

use new technology to provide renewable energy and clean air for a self sustainable

design. It aims to establish an innovative landscape solution the current over

engineered river channel treatment and to balance between developing the

economic growth from the Shenzhen Area while preserving ecological valuable area

as a greenbelt in Hong Kong for future sustainable development use.
