| 摘 要： | 针对西部山区县级土地利用总体规划修编工作中暴露出的制图尺度问题,以四川省甘孜州为例,在土地利用制图成果的基础上分析了该区内石渠、甘孜、乡城不同尺度的县级土地利用制图效果。通过对比,探讨了西部山区土地利用制图适宜尺度的选择。结果表明：（1）不同尺度下县级土地利用制图在保持精度前提下,更注重经费和人力投入来合理选择尺度。（2）西部山区土地详细规划制图宜采用大比例尺（1∶5万或更大）;县级重点城镇的土地详细规划,以1∶500或1∶1 000为主。土地利用总体规划制图,州级重点县可以考虑1∶1万-1∶5万尺度,重点城镇采用1∶1 000和1∶500;一般县宜采用1∶5万-1∶10万的尺度;而其他如位于高寒牧区的县可以采取1∶10万-1∶25万的数据。

| Abstract: | With the map scale problems exposed in revision of land use planning in western mountains, this paper analyzes the quality of county-level land use maps with multi-map scales in Shiqu, Ganzi and Xiangcheng counties of Ganzi State, Sichuan Province. Based on these, it discusses the land-use map scale selection in multi-map scales. The results indicate that： （ 1 ） County-level land use mapping with different map scales primary request the accuracy loss, and a reasonable land use map scale selection should be empathizes on the financial fund support and human power. （2） In western mountains detail land planning map, 1 ： 50000 maps scale or bigger is suitable; a 1 ： 500 or 1 ： 1000 map scale is suitable for key town in procession of county detail land planning. For land use general planning mapping, scale from 1 ： 10000 to 1 ： 50000 is more suitable for key counties, and key town may use 1：1000 and 1： 500; scale from 1： 50000 to 1： 100000 is suitable for general counties; and other counties which belong to alpine regions may use a scale from 1：100000 to 1：250000. |
