The United States set up the world's first national park system in 1916. Since then, it （ serve）as a model for other countries that try to protect the environment better and let people enjoy nature.
A national park is a reserve （保护区） of land （own）by the government and protected from human development and pollution. Now China is planning its own national park system. On Dec 5, China passed two plans for national parks （protect） the giant panda, Siberian tiger and Amur leopard.
But national parks are not only for animals. In mid-2015, China started to build national parks in nine provinces. most famous one is the Sanjiangyuan national park on the Qinghai-Tibet Plateau. It aims to protect China's water source. Sanjiangyuan, or "Source of Three Rivers", isthe Yellow, Yangtze, and Lancang rivers start.
Before this national park project, China had set aside thousands of nature parks, forests and scenic areas as protected areas. , they haven't been managed well because too many different organizations have been involvedthe protection of different areas. Under the new plan, national parks will cover big areas and include different protected areas.
For example, the habitats of wild pandas lie in different provinces and（divide）into even smaller pieces by railways, roads and power lines. This makes isolated panda groups more open to（ dangerous）. The panda national park will cover all the habitats and make the protection of animals as comprehensive as possible.
But this increased protection doesn't mean national parks will shut their doors to humans. Instead, the new system will offer people a chance to （ deep） feel nature.
