Preservation work is to start at Zhoukoudian, the site of a major archaeological and anthropological find in the 1920s.
Repairs will be carried out to the caves where the remains of Peking Man, an ancient ancestor of Humans, were found.
Some 2 million yuan, or US$240,000 is being spent to protect individual places from the elements.
Experts say Beijing's hot-and-cold weather is the biggest risk to fossils.
The long-anticipated blueprint of the Zhoukoudian World Relics Park will also be made public when the repairs begin next Thursday.
