摘　　要：针对当前农用地估价系统存在估价精度低、时实性差的问题,提出了一种基于GIS的农用地实时动态精准估价方法,并基于ArcGIS Engine二次开发技术进行了原型实现。本研究主要采用高效的GIS技术,以地块为单元精确定位评价对象,且综合更多的现地测量信息,以高效地辅助农用地估价工作精准的进行。实验结果证明:该方法能够提高农用地估价的时实性、准确度和动态度。To solve problems that the current price evaluation work of agricultural lands （PEWAL） is of low evaluation accuracy and weak real-time, an accurate price evaluation model of agricultural lands at land-parcel scales based on ge- ographical information system is presented, and a simulation system is developed to test the model based on ArcGIS En- gine in this study. To efficiently assist the PEWAL with accurate and quick completion, the model takes geographic infor- mation system technology with high efficiency, accurately locates at a land parcel as an evaluation unit, comprehensives parameters measured in situ. Experimental result shows that the model can be easily implemented and is capable of en- hancing real-time, accuracy, and dynamics of the PEWAL.
