The province is a key region for our country to return land to forest. This paper analyzed the importance to carry out the strategy of ecoagriculture deveolpment for Guizhou karst region. It also stated the target and connotations of ecoagricultrue, and expounded the principles in the development of ecoagricultrure. Finally, the authors, according to the regional features of Guizhou karst mountain area, proposed the four models (such as selfsupport in grain, ecoeconomic type of forestry, beneficial type of livestock and valueadded type of agricultural products processing) of ecoagriculture development.
