Based on the energy-input and output principle in the system.10 main planting systems in coastasl upland area in Putian City of Fujian have been analysed using chief-factor analysis and cluster analysis methods.These systems were divided into 5 types:1) high input with low output type;2) low input with low output type;3)intermidiate tpye;4)high input with high output;and 5) high output with high efficiency.Different types of planting systems have been comprehen-sively evaluated,it will provide the references for further adjustment and development of planting structure in Fujiann.
