摘要:
塔里木河下游不同沙化土地类型之间的动态变化在我国西部干旱、半干旱地区内陆河流域具有典型的代表性。通过对塔里木河下游尉犁县沙化土地空间分布特征、不同沙化土地类型之间的变化规律、植被和植被盖度空间分布动态变化以及近年来上游输水情况及其对植被影响的研究分析认为，自然因素对沙化土地类型、植被盖度变化及空间分布在短时间内不产生明显作用；而人类经济活动的干扰，诸如流域地表水资源分配不均、水资源开发利用过度、生态用水得不到保障和人为破坏地表植被是造成沙化土地类型变化和植被盖度变化的关键因素。近年来塔里木河下游生态输水是导致该区域沙化土地类型和植被盖度好转的决定因素，垦荒是造成局部地表植被减少和土地沙化程度加重的主要因素。
Abstract:
The dynamic changes of sandy desertification land types at lower reaches of Tarim River Basin is a typical exemplification in inland river basin of west arid and semiarid areas in China. Through studying and analyzing on spatial distribution features and changing regularity of sandy desertification land types, spatial distribution and dynamic change of vegetation and its coverage, impact of upper ecological water transfer on vegetation，it was found out that natural factors did not impose significant effects on sandy desertification land types, vegetation coverage, and their spatial distribution in short period，but interferences from the human economic activities, such as unbalanced allocation and overusing of water resources, shortage of ecologic water, damaging to ground plant were significant factors. Ecologic water transfer to lower reaches of Tarim River Basin in recent years was the key factor to turn sandy desertification land and vegetation types better，however reclaiming wasteland was the key factor to decrease ground plant and aggravate the degree of sandy desertification land.
