基于MapInfo- EXCEL的土地级别划分方法研究——以辽宁省岫岩县为例

摘要

以辽宁省岫岩县为例,探讨了基于GIS技术的土地级别划分方法.以国家《城镇土地分等定级规程》为基础,详细分析采用单元总分频率曲线法进行土地定级,并以“自然划分”、“标准差”方法进行界线的修正及确定.结果表明此种方法能够有效地提高土地级别划分的精度和准确性.%The town-land classification is the fundamental work of the town-land management. With Xiuyan County as an example, this paper studies the techniques for land grading based on GIS technology. On the basis of the Procedure of Urban Land Gradation, and using the method of total frequency, the paper modifies and corrects the results by means of "natural division" and "standard deviation". The results confirm that this method can effectively raise the precision and accuracy of land grading.
