摘要

传统的等高线绘制方法受线性插值的限制，在研究区域变量时误差较大。本文采用非线性插值和三角形质点插值方法，大大提高了拟合精度。在广东西北江地区地质灾害气象预警系统中对新的等高线绘制方法进行了验证，验证结果令人满意。

Utilizing a improved contour plotting method based on delaunay triangulation network in geologic hazard prevention

Traditional contour plotting method, limited by linear interpolation, has much error in studying regional variables,. It is advanced in this paper by utilizing nonlinear interpolation and triangles mass points interpolation methods, which greatly improve the fitting precision. New contour plotting method is validated in meteorological early-warning system of geological disaster in Guangdong XiBeiJiang region and the verifying result is satisfied.
