Abstract: “Non-grain” and utilization monitoring are important contents of utilization management after construction of high-standard farmland. Evaluation indexes are constructed from four aspects in this paper:natural attribute, ecological attribute, location attribute and non-grain, and the index weight are determined by Delphi method. Overlaying the geographical monitoring data on the basis of high-standard farmland plots, the index values are obtained through spatial analysis to monitor and evaluate the current situation of high-standard farmland construction and utilization. The results show that the indexes of location attribute and "Non-grain"are relatively good, and that of natural attribute and ecological attribute are not good with the poor performance of the ratio of soil organic matter content and the effectiveness of shelter belt in them. The index system established in this study is reasonable and effective, and the method of index data acquisition is feasible, which can achieve the goal of monitoring and evaluating the effectiveness of high-standard farmland construction.
