Recently, a special exhibition named "Our National Parks" was launched at the China Geological Museum in Beijing. The exhibition focuses on displaying the ecological features of Chinese national parks and on helping the public understand the significance of national park construction in maintaining authenticity and integrity of important natural ecosystems, as well as in maintaining biodiversity and ecological security, in promoting the harmonious coexistence between man and nature. The exhibition not only offers rich graphic content and video images, but also many precious animal and plant specimens, including Siberian tigers, giant pandas, Tibetan antelopes, wild yak, etc. Photos: Li Hao/GT
