摘　　要：结合临沂市地下水资源观测资料及特点,研究地下水位等值线生成算法,尝试在GIS组件--MapObjects环境下,采用不规则三角网绘制等值线的方法在MapObjects图层上生成地下水位等值线。结果表明,在MapObjects图层上绘制的等值线准确、美观,而且满足用户对等值线动态绘制的需求,应用前景广阔。According to observation data of Linyi and its characteristic, this article studied algorithm of building water isoline, and tried to apply TIN to build water isoline based on MapObjects. The result proves the water isoline builded by this way is accurate, beautiful and it can fit the users＇requirement, so it will have wide spread in application.
