摘要:
通过对拉萨河下游河谷实地调查和IKONOS、QuickBird的影像解译结果,查明了该区沙尘源地具有沿河谷及河谷两侧分布、分布地貌部位多样且呈小面积零星分布的特征,并对城市环境和工农业生产造成了严重的风沙危害.通过分析表明高原气候条件下脆弱的生态环境、沙源特征和植被条件,以及近年来强烈人类活动的干扰是风沙灾害的主要原因.从气候和人类活动变化趋势分析表明,未来15年内气候变化不利于削弱风沙灾害强度;人类活动尽管对风沙灾害强度的加强作用会逐渐降低,但总体上仍起强化作用,如果不采取人工治理,拉萨河谷风沙灾害就趋于加强的态势.
Abstract:
Based on the field survey of the lower Lhasa river valley and the interpretation results of IKONOS and Quick Bird’s video,finding out the source of sand and dust storm in the valley distribute along river valley and its two sides,the distribution’s physiographical places are varety and sporadic,small size.Such feature cause serious hazards of sand to the urban environment and agricultural production.The analysis show that the vulnerable ecological environment in the plateau climate conditions,the characteristics of sand sources,vegetation condition and the intense human activities are the main causes of disaster.Finally,the analysis of human activities and climate change trend indicates that in the the next 15 years,the climate change unsuitable weakened sandstorm’ strength,human activities’ intensity of strengthening effect to the sandstorm will gradually decrease,however,in general,it is still has the strengthening effect.Lhasa river valley will tend to strengthen the disaster,if the human measures not be taken.
