青海省公路沿线积雪信息的遥感提取与分布特征分析
Remote Sensing Extraction and Distribution Analysis of Snow Information Along Highways in Qinghai Province
摘要
Abstract
Using snow cover information from MODIS monitoring,and based on key technologies such as spatial extraction of snow cover information along highways and automatic production of snow graphics,the issue of scarcely distributed meteorological stations for snow monitoring along highways can be effectively solved.This enables snow cover information monitoring in Qinghai Province,especially along highways,and allows for refined meteorological services.The results show that:1)Using snow cover information from MODIS monitoring,the snow cover area,snow cover days and snow depth during the snow season in Qinghai Province from 2005 to 2020 are obtained.The data are verified by ground-based observations and found to be in good agreement with the observed snow conditions;2)During the snow season from 2005 to 2020,the snow cover area,snow cover days,and snow depth in Qinghai Province detected by remote sensing showed an generally increasing trend.However,spatial differences were also identified.The high-altitude areas such as Yushu,Guoluo,and Haibei experienced a wide distribution of snow;3)The sections of Golmud-Tanggula(G109),Maduo-Chengduo(G214),Datong-Menyuan-Qilian(G227),Qilian-Tianjun of Su-Huang Line(S207),and Maduo-Maqin-Gande of Hua-Shang Line(S205)are all located in high-altitude areas of Qinghai Province with abundant snowfall.Therefore the snow cover conditions along these highways were relatively severe.关键词
