In this paper, according to the development of agricultural production, five basic geo-morphic characters in Fujian are given. Direct and indirect effects of these characters on ag-ricultural production are analysed. Then, this paper discusses the relation between geomor-phology and agricultural natural hazard and points out that there is a close relationship bet-ween geomorphology and natural hazard such as flood, typhoon, soil and water erosion, hill-slopes slip, and mud-rock flow. This paper suggests that the region with steep slope, heavy rainfall, and black mica granite is the weak agricultural ecological region in Fujian.
