摘要
近50a来,塔里木河流域产生的土地荒漠化等生态问题的原因是人类活动对水文过程的干扰所造成.基于月时间尺度的水文资料,采用对比分析法,从径流的年内过程、年际过程、来水过程等方面,分析人类活动对流域水文过程的干扰特征.根据研究区水资源开发利用的特点,采用数理统计法———有序聚类法和游程检验法,计算出了流域人类活动对水文过程的干扰点.
The important factor which has caused the ecological problems such as land desertification in Tarim River Watershed is human activities disturbing the natural hydrological process in recent 50 a. Based on the monthly hydrological data and the method of contrast analysis, the human disturbance characters on hydrological process of Watershed are analyzed from the monthly runoff processes in year, years and the tendency of runoff of May-Oct. process in years. According to the features of human activities in study area, the disturbance point is calculated with the method of mathematical statistics--orderly cluster analysis and runs test.
