Land using layout can mostly exert the using extent and the economic benefit of the land.The intensive using level can be improved by confirming the reasonable planting structure and subarea of the crop.The article compartmentalizes the evaluation element son the basis of diagnoses about basic data of Zhaoy uan,the evaluation facto rs and the genes,which influence the main crop output are filtrated and ascertained acco rding to the correlation and regression analysis,quantized classification and ascertained the weightiness of the indexes, integ ration evaluation and optimum planting subarea of the land productivity are made.The results present as follows:the principal influence factor is distinctness in different crop;the same plot may have different evaluated classification on the different crop product ivity;relatively excellent planting scheme and compartmentalizing the optimum planting subarea of each crop should be made according to the principle of optimum benefit.
