摘　　要：研究了村村通公路工程的GIS本质——最小生成树的原理及解法以及与GIS有关的出口路终点和起点位置的选择,线路走向的确定,进自然村道路的确定等问题,提出了以自然村人口重要度为权的加权距离法确定出口路的终点,用最小二乘法、地图代数理论中的欧氏障碍空间最小生成树和最短路径分析法确定出口路线走向、自然村进村路等。Several GIS-related issues in the village link highway project is discussed, including the location choice of the starting and destination point, the determination on the trend of the road line and the road access to the villages. The choice of the destination of the export road with the methods of the distance law that weighted with importance for populations of the natural villages is presented. The determination on the trend of the road line and the road access to the villages with the methods including the least-square method, the Euclidean mininum Spanning Tree and the Euclidean shortest path with obstacle in the theory of the cartographic algebra is proposed.
