i. It adopts the water purification technology
of efficient vertical flow artificial wetland
system, builds artificial wetland system

in nearby region which helps to stabilize regional
climate condition and adjust regional climate.

Supplementary system with solar and
wind energy:
In tea stream valley, people
can see the road lamps with solar and light
energy. It fully makes use of meteorological
resource to realize the power generation day
and night and supply other use of electric-
ity. This supplementary system of solar and
wind can improve stability and continuity
of systematic power supply. As wind energy
is stronger at night without sunshine, this
perfect supplement can save solar panels to
greatly cut the cost of system.

Diversified and beautiful ecological pas-
sage:
Various ecological passage designs
can effectively protect original tea garden,
Sanzhoutian reservoir, and creature's living
condition so as to guarantee safe communica-
tion and migration of creature and their diver-
sity. It mainly includes Red-feather trestles,
anxiety-free corridor, wetland corridor, tea
stream trestle, tea ridge wood pavement,
ample stream Vine Bridge, bamboo stream
Cable Bridge, tea ridge corridor etc. Those
are the most unique ecology demonstration
scenery line in OCT East, especially in tea
stream valley. For instance, tea stream trestle
crosses two hills and wetland protection
zone of the branch of Sanzhoutian reservoir.
It is constructed by logs which effectively
preserves ecological environment of natural
Sanzhou tea garden. At the same time, it
secures the normal flow, water quality and
living condition of aquatic creature along
wetland protection zone of Sanzhoutian
reservoir branch to realize continuity and
diversity of existing ecological environment.
What's more, it adds attractive scenery in
valley from where people can look around
this pure natural tea garden. The most amaz-
ing is the whole design not only observes
This artificial wetland integrating with the
functions of popular science education, environ-
ment preservation and scenic spot includes two
forms: diffusion flow wetland and vertical flow
wetland. Diffusion flow contains two desilting
ponds, one aerobic pond and two plant ponds
with the size of 7000 square meters. Vertical
flow wetland includes one desilting pond and six
vertical plant ponds with the size of 8000 square
meters. The system has particular structure and
flow model. Artificial wetland system water
purification is an ecological project method. Its
basic principle is to plant certain wetland vegeta-
tion on the fillers to establish a artificial wetland
ecological system.
The water filtered by this system can reach
the standard of 3 degree to be discharged into
Sanzhoutian reservoir directly. So it suits for the
preservation of Sanzhoutian drink water and land-
scape water, the whole system has relatively small
size with long-term and stable operation. Besides
peculiar wetland plant, there grows a lot of aquatic
plants perfect for appreciation. For example royal
water lily, water lily, penh calamus and American
arrowhead etc. all these create beautiful scenery of
flowering in four seasons. This wetland not only
plays the role in supplying and conserving water
resource, degrading pollutant, preserving plant
diversity and living water resource, it also nurtures
some precious frogs, and there increases more
and more creature types, so there is a distinctive
environmental coordination function and ecology
effect. Moreover, most districts in Sanzhoutian is
mountain and hill, many scouring ditches form
natural runoffs. Artificial wetlands then play great
role in flood control and drought resistance. And
