  We present a large scale survey of CO outflows in the Gem OB1 molecular cloud
complex and its surroundings using the Purple Mountain Observatory Delingha
13.7 m telescope. A total of 198 outflow candidates were identified over a
large area ($\sim$ 58.5 square degrees), of which 193 are newly detected.
Approximately 68% (134/198) are associated with the Gem OB1 molecular cloud
complex, including clouds GGMC 1, GGMC 2, BFS 52, GGMC 3 and GGMC 4. Other
regions studied are: Local Arm (Local Lynds, West Front), Swallow, Horn, and
Remote cloud. Outflow candidates in GGMC 1, BFS 52, and Swallow are mainly
located at ring-like or filamentary structures. To avoid excessive uncertainty
in distant regions ($\gtrsim$ 3.8 kpc), we only estimated the physical
parameters for clouds in the Gem OB1 molecular cloud complex and in the Local
arm. In those clouds, the total kinetic energy and the energy injection rate of
the identified outflow candidates are $\lesssim$ 1% and $\lesssim$ 3% of the
turbulent energy and the turbulent dissipation rate of each cloud, indicating
that the identified outflow candidates cannot provide enough energy to balance
turbulence of their host cloud at the scale of the entire cloud (several pc to
dozens of pc). The gravitational binding energy of each cloud is $\gtrsim$ 135
times the total kinetic energy of the identified outflow candidates within the
corresponding cloud, indicating that the identified outflow candidates cannot
cause major disruptions to the integrity of their host cloud at the scale of
the entire cloud.
