| 摘 要： | 结合塔里木河流域近50多年来的水文、气象及遥感等资料，采用数理统计方法分析了塔里木河径流量变化对下游地区沙漠化的影响。结果表明，自20世纪50年代以来，由于人类活动的干扰和塔里木河不同河段水资源分布的不均匀，使塔里木河下游的径流量在不断的减少，导致下游河段断流，湖泊干涸，并对下游地区的地下水位、植被、沙尘暴及大风天气、沙漠化程度都产生了负面影响。而且河流径流量、地下水位、植被、沙漠化之间是相互影响，相互制约的，存在着内在的联系，在整个生态系统中牵一发而动全身，尤其是在生态环境脆弱的干旱、半干旱区。因此，在对水、土等资源的利用过程中，要注重整体效益。

| Abstract: | Based on data of thydrology, meteorology and remote sensing informatio in Tarim river basin for nearly 50 years, statistics methods were used to analyze the effect of runoff change on desertification region downstream of the Tarim river. The results show that since 1950s, due to the interference of human activities and the different of the Tarim river water resources uneven distribution, reduction of water consumption in the Tarim river downstream led to the downstream river cutoff, lakes dry up, and negatively affected underground water level of downstream, vegetation degree of desertification, dust storms and strong wind weather. These factors are mutually influenced, mutually constrained. There are internal relations among these factors, which has the extremely important link in the entire ecosystem, especially in the fragile ecological environment in the arid and semi arid areas. Therefore, attention should be paid to the overall efficiency in the using process of resources such as water and soil. |
