The Heihe Ecological Park in Zhangye, Northwest China's Gansu province presented beautiful pictures on Sept 1 with thick trees bathing in the morning sun.

Taking the main stream of the Heihe River as the axis, the ecological park was designed with artificial lakes, fitness trails, plazas and parking lots. It has become the just place for residents who crave for leisure time in pure natural scenery.
