%X Our country has been in the time when the industrialization and urbanization makes the trend of cultivated land conversion irreversible since the end of 90's. Inefficient utilization of land resources and soil contamination has led to the decrease of cultivated land and the quantity of food per capita. People at home and abroad have paid close attention to the food security again. The effective measure to deal with these problems is to improve land utilization efficiency through technological innovation. This paper tries to put forward the indicators for analyzing the Comprehensive Efficiency of the Cultivated Land Utilization by the principal component analysis, and on the basis of comprehensive benefit, tries to put forward the standards for discerning the patterns of the cultivated land utilization by cluster analysis, and the Comprehensive Efficiency of cultivated land use in Shandong Province have been evaluated. The results show that the stability of cultivated land use is poor. The land use patterns in some areas are improved associated with a fluctuated feature, but in other areas there is a deteriorated trend in land use pattern. At present, many developed areas are on the track of extensive land utilization. It is suggested that the central authorities should take measures to ensure the economic benefits while not compromising ecology benefit and human welfare. In the main grain production areas, in order to improve the ecology benefit, it is better to apply chemicals and fertilizer scientifically, strengthen the construction of the irrigation and water conservation infrastructure on the base of maintaining the present better ecology benefit. Meanwhile, it is necessary to continue to implement the agriculture supporting policy in the main grain production areas and bring a further increase of the economy benefit to realize the increases of the agriculture production and the farmers' income, to achieve the national macroscopic grain security goal.
