| 摘 要： | 3S在土壤资源调查和管理中已成为重要的工具。笔者以郑州市土壤肥力监测采样为例，具体阐述了3S技术分别在土壤布点与采样各个环节应用，包括：采用RS和GIS技术更新土壤图；室内借助GIS技术进行土壤样点的初步布设，输出布点草图和坐标；野外根据室内GIS所布样点为中心进行GPS定位采样，同时根据实地情况修正土壤样点分布图。应用结果表明：（1）更新前后的数据显示，随着城市化进程，郑州市土壤资源的数量和类型都发生了显著变化；（2）利用MapGIS6.5生成2.5×2.5 km网格，初步布设土壤样点110个；（3）野外利用GPS定位采集土壤样本105个，同时获取了采样点的空间地理信息。3S在土壤布点与采样中的应用为进一步的土壤性质由点尺度到面尺度的扩展分析等后续研究奠定基础。

| Abstract: | “3S” have become the important tools in soil resource investigate and management. The author states the application of “3S” techniques in soil spot arrangement and sampling respectively taking the soil fertility monitoring sampling as the example. The application includes updating the soil spot arrangement base map using RS and GIS techniques; primary arranging and adjusting the soil spot with gridding method by the aid of GIS technique, and then exporting the spot location sketch map and spot coordinates; using the GPS for spot position or correcting the spot arrangement map and coordinates according to the spot factual condition in outdoor soil sampling. The results shows: (1) Comparing the soil map in 1982 and updated soil map, the data indicated that the obvious have change happened of soil amount and soil type with the development of urbanization. (2) Using soft MapGIS6.5 created 2.5×2.5 km grid and primary arranged 110 soil spot. (3) Selecting 105 soil sample with the guide of GPS for spot position, and obtaining the actual geography information of soil spot. The application of “3S” in soil spot arrangement and sampling will be the base of soil research in future, i.e.，farther soil property analysis from spot scale to area scale. |
