摘　　要：采用LSSVM模型技术对南京江北新区区域进行地面沉降监测,并对其观测值和预测值进行了对比。实践证明,LSSVM模型技术以其运算速度快、运算量小、运算简单的特点,解决了求解相当耗时的二次规划问题,大大缩短了运算时间,在地面沉降监测中发挥了重要的作用,拥有良好的推广价值。The LSSVM model is used to carry out the ground subsidence monitoring in the core area of Nanjing Jiangbei,and the observation and forecast values are compared. LSSVM model technology to the operation speed fast,small amount of computation,the characteristics of simple operation to solve the solution quite time-consuming quadratic programming problem greatly shortens the operation time and in ground subsidence monitoring play an important role,with good promotional value.
