近50年来人类活动对自然水文过程的干扰是造成塔里木河流域土地沙化等生态问题的重要因素。以月水文资料为基础，采用对比分析的方法，从年、年各月径流过程及5-10月径流变化趋势等方面分析人为干扰对流域水文过程的影响特征。数年的过程。根据研究区人类活动特点，采用数理统计方法——有序聚类分析和游程检验计算扰动点。
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.
