摘要
多年冻土作为大兴安岭西坡的重要组成部分,其变化发展深刻地影响着该地区的工程经济建设和生态环境建设.为进一步了解大兴安岭西坡多年冻土区的地温变化情况,基于地温波动理论,利用Origin软件对根河、伊图里河和满归3个地温监测站的多年冻土地温进行非线性拟合,建立相应的地温曲线拟合模型对当地多年冻土地温进行模拟研究.研究结果表明:一定时段内,各站点的地温模拟效果较好,尤其是冬、夏两季,地温模拟精度高于0.99.
Permafrost as an important part of the western slope of the Da Xing’anling Mountains,its development change profoundly affects the engineering economic construction and ecological environment construction.In order to further understand the variation of ground temperature in the permafrost region on the western slope of the Da Xing’anling Mountains,based on the theory of ground temperature fluctuation,the origin software was used to carry out nonlinear fitting of the ground temperature of permafrost in Genhe river,Yituli river and Mangui monitoring station,and the corresponding ground temperature curve fitting model was established,so as to simulate and study the ground temperature of local permafrost.The results show that the ground temperature simulation effect of each station is better in a certain period of time,especially in winter and summer,the ground temperature simulation accuracy is higher than 0.99.
