Protective farming mode selection method

The invention relates to a method for selecting a protective farming mode, which is characterized by comprising the following steps: 1) data collection: soil data, climate data, geographic data and production habit data of a mature area and an area to be implemented in different modes are collected; 2) preparation of mode selection: a decision unit and an index of each protective farming mode aredetermined according to the data of the mature area; 3) construction of a projection pursuit analysis model; 4) construction of a similarity evaluation model; 5) model selection: the protective farming mode corresponding to the mature area with the highest similarity to the area to be implemented is selected as the protective farming mode of the area to be implemented according to the level of similarity. The invention selects a proper protective farming mode for the area to be implemented by constructing a protective farming mode selection mode, and the whole process is completed by computeranalog simulation without
