The natural disaster in China is very serious and has caused many damages to life

property

environment and society. Natural disaster prevention and control is a systematic engineering for reducing economic losses caused by disaster and ensuring the social sustainable development. In this article

some basic theories of natural disaster prevention and control engineering are analyzed

which include disaster geography

disaster ecology

disaster economy and disaster engineering. Then according to its feature

the natural disaster prevention and control engineering is categorized into four types: geological project

water conservancy project

ecological project and oceanic project. At last

some successful examples of each type are introduced such as the control project of Lianziya dangerous rock mass and Huanglashi landslide in the Three Gorges area of Yangtze river

Doujiangyan water conservancy project

the protective forest systems in "Three Norths" and sea dike project. It is pointed out in the end that natural disaster prevention and control is a complex systematic engineering that requires cooperative work from diverse disciplines.
