摘要
高原地区地形复杂,在工程测量及科研试验过程中,操作人员在湖泊表面进行定点取样时,由于自然条件、资金及人力资源的限制,用常规的测量方法难以实现水深及湖面距离的准确测量。以阳宗海泉涌点附近8 m等深线实地测绘为例,分析得出一种适用于类似湖泊环境等深线及湖面距离测量的简易新方法。新方法所测数据精确,对非测绘专业人士进行湖泊的等深线、湖面距离测绘具有参考价值。
Highland lakes have complex terrain features.During engineering survey and research trials,due to natural conditions,capital and human resource constraints,when a fixed-point sampling is needed on the lake surface,it is difficult with the conventional measurement methods to achieve accurate depth and the horizontal distance.Taking the mapping process of 8 m isobath near Yangzonghai lake gushing point as an example,a new simple method is suitable to the lake isobath and surface horizontal distance measurement is put forward and analyzed.The new method has great reference value for non-mapping professionals to map lake isobath lines and lake surface horizontal distance.
