摘　　要：结合Surfer独特的强大功能，提出一种在多岛屿地图上绘制气象要数等值线色块图的自适应方法，并将该方法应用到气象资料的自动成图领域中。针对Surfer在绘制等值线方面的各种缺陷，即不能向外白化多岛屿地图和自适应性差，给出对网格文件、白化文件、色块等级文件的制作或改进方法，再结合程序对Automation接口的调用，设计整个过程的算法框图和主要代码，以浙江省1971～2000年的气象资料为数据源，自适应地实现了在浙江省地图上的各种气象要数等值线色块图。结果表明绘制的等值线色块图具有良好的可比性，可扩展性和实用性。An auto-adapted method for drawing up contour maps for multi-island areas is devised by means of the powerful and unique capability of Surer. Through analyzing various flaws in contour drawing with Surfer （incapability of whitening outward the multi-islands maps and poor adaptability）, the methods for improving and making the grid documents, whitening documents, and block level documents are given. In combination with the calling of the Automation interface, the algorithm diagram and main codes of the entire process are designed. Taking the 30-year meteorological data of Zhejiang Province as an example, the meteorological element contour map superposed on the ZheJiang Province map is obtained by the auto- adapted method, which prove that the method has good comparability, expandability, and applicability
