In this paper, based on experiment data from different treatment such as grass-bush band intercropmg. Grass-crop band rotation for 6yelus, different planting patterns were classified with their conservation benefits And its accuracy is verified using Bayes stepwise discrimination analysis.Then, the Conservation benefits of ecch planting pattern was analyged and evaluated. The results show that the sequence of conservation benefits from high to low is like: caragana→intercroping of caragana and grss→grass alone→band intercroping of crop and grass→crop levelling planting→crop general planting.
