数据概况：2005年9月23日至9月30日和2005年11月5日至11月9日，中科院寒旱所遥感室在黑河中游莺落峡水文站至正义峡水文站之间一共测量了21个水文断面。
\n\n数据采集过程：利用中海达HD8080 GPS接收机两台和南方测绘公司DS3型号水准仪一套，采用GPS与水准测量相结合。断面测量主要包括两个步骤。首先是利用两台差分GPS在选择的断面河岸两边或者一边选择测量高精度的控制点，两台GPS 接收机同步观测30 分钟。然后在这些控制点基础上利用水准仪进行断面的连续测量，根据河宽在断面上布设一定数量的测深垂线，测各条测深垂线的水深和起点距，测点在主槽部分较密，滩地较稀，主槽部分两点之间间距为2米。本数据可以为黑河中游的地表地下水水文模拟提供关键基础数据资料。

\nData acquisition process: using two sets of zhonghaida hd8080 GPS receivers and one set of DS3 level of Southern surveying and mapping company, combining GPS and leveling. Section survey mainly includes two steps. Firstly, two differential GPS are used to select high-precision control points on both sides of the river bank or on one side of the selected section, and two GPS receivers are used to observe for 30 minutes simultaneously. Then, on the basis of these control points, the level is used for continuous measurement of the section. According to the river width, a certain number of sounding plumb lines are arranged on the section to measure the water depth and the starting point distance of each sounding plumb line. The measuring points are relatively dense in the main channel part, and the beach is relatively sparse. The distance between the two points of the main channel part is 2m. This data can provide the key basic data for the hydrological simulation of surface groundwater in the middle reaches of Heihe River.
