|A man-made Lake: Dong Li Lake
I. Brief Introduction
Creating a healthy and wonderful life is the purpose of Vanke. Every
staff in Vanke hope that they can make a comfortable habitat for the
owners. Under such threoies, the Dong Li Lake Project which developed
by Vanke Co. Ltd included a 100000 acreages man-made lake which can

Student Water Ski Championship which is held four years one time will
be started. Staying at home, owners can feel about the exciting atmosphere
of Intenational Championship and appreciate the super level competition.
Besides Water Ski Championship, owners who live in this community
every day can also feel about the influence on living condition which
is brought from the man-made water ski lake. Every owner can take
part in this water envoirment because of this kind of design.They
can get the feelings about the water atmosphere. Also they can boat
on this lake to appreciate the wonderful feeling!
The range of manmade lake
II. Data of lake
The total measure of the water ski champion arena is 100 thousand
square meters. The length is nearly 700 meters and the width is
80 meters. A man-made jumping area whose length is 100 meters located
in it. There are two original islands that echo each other at a
distance. The competition dock is about 850 square meters, for berth
boats in the water skiing competition; near the dock, there has
racing boat slope in the single side, about 500 square meters, for
embarking and disembarking; rostrum and bleachers all located in
the Binhu Park which in the north side of the competition arena,
rostrum is about 600 square meters, bleachers which near the 2 side
of rostrum is about 800 square meters.
III. Water quality preservation
i. permeating water channel
Permeating water channels located in the south side of the first
period project, 9000 square meters. In both east and west side have
upcomer and downcomer, the upcomers receive the water that clarified
by the manmade damp field, then the clarified water flow into the
downcomers autumnally. At last, the clarified water will back to
the competition arena by these channels.

ii. Using of the Rainwater
Because of the exploitation and depredation of the natural resources
by human people, more and more natural resources have decreased
rapidly. As one of the essential natural resources for human, water
resource is facing a serious risk. Tianjin is a serious water-lack
city in China, how to save our water resources more effectively
is the problem that we must to face together. For saving water resources
more effectively, Dongli Lake project have thought the exploitation
of rainwater in the beginning of project design.
Rainwater storage in the villas. In each villa, we have the storage
facilities to collect rainwater that drop onto the house surface.
The storied rainwater is used to water the grass field of the villa.
Rainwater channel collection in the project. In the project, we
designed rainwater channels to made the rain flow into the water
system of living area to renew the water of damp field and water
landscape, these channels also have landscape green effect. Only
if the especially big rainstorm needed to be drainage into the rain
channel which out of living area by drainage channel, the rainwater
in the living area will be no drainage in the regular years. It
will save a great deal of landscape water and green field irrigation

iii. Manmade damp field
Manmade damp field system water-clarified technology is organism
dealing method. Its basic theorem is as follows: Grow special damp
field plants in the special filling materials to create a manmade
damp field ecosystem. When the polluted water flow through the system,
the polluted substance and nutrition substance will be absorbed
or decomposed by the system. By this way, the water is clarified.
The course of manmade damp field water-clarify contains physics
subsiding, root system interception, chemistry precipitation, soil
and roots absorbing, microbe metabolism and so on. And microbe takes
the main effect.
The main effect of Dongli Lake manmade damp field system is to
clarify the water of water skiing competition arena. Because of
the organism dealing capability of the damp field, the water in
the manmade lake of water skiing competition arena can be use in
circles. The water circulation not only save the supply water, but
also bring us beautiful water landscape.
And because the damp field system is created by reed, cattail,
calamus, 千屈菜, cannas and other aquatic plants, the damp field have
s different landscape. The damp field ecosystem creates a damp field
park and offers the proprietors an excellent place to travel.

IV. Landscape design of the embankment vicinity
i. Metasequoia Square
The Square is located in the east side of water skiing building,
200 meters away from the building. It’s the first landscape space
to tie up the living area and the outside space, and it is also
the beginning of Qingjing Street.
In the east side of the street, there has a manmade mountains and
waters landscape which is 2350 square meters. An embossment wall
that signed the project name is located in the north side of the
green slope. The top of the manmade mountain is 11.25 meters high.
The water landscape has 3 floors, water drop from one floor to the
next one, through the high and rich forest and landing stage, then
flow into the competition area park.
ii. Qingjing Street
Qingjing Street is 16 meters wide totally, carriageway is 6 meters
wide, the separated space in the middle of the street is 4 meters
wide, and in the 2 sides of the street there have 2 sidewalks which
are 1.5 meters wide. Driving on the street, you will see a lot of
trees in the side just like you are driving in a scenic area.

Binhe Park is in the middle of Qingjing Street and competition area,
nearly 1000 meters long and 30 meters wide. It’s an important water
landscape banding in the living area.
In the park, there have a water skiing bleachers and a reserved
field that can build a provisional bleachers. The International
Water Skiing Game will be hold with solemnity in the next year.
The landscape field is uninterrupted and undulated landforms. In
the park, people grew green forest which has vivid administrative
levels; it shows the particular natural environment totally. Near
the embankment, 3 pavilions and veranda which have different structure
styles located in the end of landscape banding square and respond
the entrance of living area. It shows the scheme concept of natural
iv. Neighborhood Central Square
Neighborhood Central Square is extended from neighborhood commercial
centre to the competition water area, about 2200 square meters.
The main entrance of neighborhood center which face the competition
area park is Linyin Square. The square has near water tableland,
landscape balcony, resting pavilion and sport facilities, all of
them bring the villa life vitality.
v. Building Sandy Beach Square
