传统的基于Delaunay三角网格等值线提取方法采用线性内插，对于研究区域变量时，误差较大。提出了采用等值点非线性计算和三角形重心内插等方法，对传统的基于Delaunay三角网格等值线提取方法进行改进，显著提高了对区域变量拟合精度，并在广东海岸带降雨量数据中对该方法的实用性进行了验证。

Traditional contour plotting method may have big errors in studying regional variables, due to linear interpolation. In this study, we use nonlinear interpolation and triangle mass point interpolation methods, which can greatly improve the fitting precision over the traditional contour plotting method. The new contour plotting method is validated using marine geological survey data, and the verifying result is satisfied.
