The invention discloses an electrospinning fiber environment control system, belongs to the field of electrospinning, and aims at achieving the purposes that the electrospinning temperature and humidity are constantly controlled, and spinning space is compact and adjustable. The electrospinning fiber environment control system is characterized in that an inner side wall of an air suction groove opposite to a transverse blowing port is provided with an air suction port adaptive to the transverse blowing port, a partition wall separates the inner side wall provided with a transverse air suctionport from an outer side wall opposite to the inner side wall, and an upper side wall corresponding to the space formed by the inner side wall with the transverse air suction port and the partition wall or the space formed by the inner side wall with the transverse air suction port, the partition wall and the lower side wall is provided with a suction fan. The electrospinning fiber environment control system has the effect that the spinning space is compact and adjustable.
