China's top political advisor, Jia Qinglin, Friday called for more efforts to build "ecological screens," to contribute to the nation's endeavor to combat floods and landslides.

Authorities should beef up measures to prevent and control ecological disasters, said Jia, chairman of the Chinese People's Political Consultative Conference (CPPCC) National Committee.

He also said authorities should plant more trees and protect and restore wetlands in areas prone to natural disaster.

Jia, also a member of the Standing Committee of the Communist Party of China (CPC) Central Committee Political Bureau, made the remarks when attending a meeting marking the foundation of the 6th Board of Administration of the China Green Foundation (CGF).

Founded in 1985, the CGF is a national non-profit organization focused on promoting afforestation campaigns in China. It raises and utilizes funds to expand green land, plant trees and protect mountains and rivers.

China has been hit by many floods and landslides this summer.

A mudslide in northwest China's Gansu Province in August killed at least 1,471, with 294 still missing.
