摘要
以新疆和田河流域玉龙喀什河同古孜洛克水文站1984—2014年的水文资料,采用Mann-Kendall法验证玉石采挖对部分流域水土流失及控制断面水文要素的影响;通过对玉龙喀什河水体含沙量年际、年内变化趋势的分析,并进行突变性检验。结果表明,水文控制断面的含沙量变化在部分月份具有显著突变的现象,突变分析指出自1994年水文测验断面的含沙量增加趋势明显,分析成果与这一时期和田玉价格涨幅大,并造成乱采滥挖现象是一致的;和田玉主采区在采玉盛期的水土流失是严重的,政府及时采取的管制措施十分必要。
Based on the hydrological data from the Tonggusluck hydrological station of Yulong Kashi river in the Hetian River Basin from 1984 to 2014,the influence of water loss and soil loss was tested and analyzed which caused by jade mining by using the Mann-Kendall method. The mutation test was carried out based on the analysis of the variation trend of sediment content in the Yulong Kashi River. The result shows that the content of the sediment changed significantly in some months.The trend of the sediment content from hydrological tested section is increased obviously caused by unauthorized mining which was induced by great demand of the jade in market. This shows that the water and soil loss in the main mining area of Hetian jade during the peak period of jade mining is serious,and it is necessary for the government to take the control measures as soon as possible.
