中文摘要	民勤青土湖人工输水作为石羊河流域综合治理的一项重要措施,对于阻止腾格里和巴丹吉林两大沙漠进一步合拢以及保护民勤湖区绿洲具有重要的意义。文中通过民勤青土湖人工输水前后植被状况的调查,分析了生态输水对流域植被的影响。结果表明:植物种从9种增加到14种;生态输水起到了增加植物种的作用;同时改变了种群结构和长势,如加速了建群种白刺的衰退,促进盐爪爪和芦苇大量发育,植被和土壤特征有朝着盐生草甸演替的趋势;尾闾湖区水分侧渗促使深根性灌木明显恢复;输水导致距水源500m范围内物种多样性差异显著,说明输水的侧渗范围小于500m。
英文摘要	Artificial eco-water transportation is an important measure for the comprehensive management in Shi yang River Basin,and has significance to prevent the Tengger desert and Badan Jaran desert from further close and protect the ecological environment of Min Qin oasis. Through the investigation of vegetation growth situation before and after water transportation,the effect of artificial water transportation to the vegetation was analyzed. The result show that species increased from 9 to 14; ecological water transportation accelerated the decline of Nitraria tangutorum while a large number Kalidium foliatum and Phragmites australis developed. Vegetation and soil characteristics showed the tendency of evolving into salt meadow communities; deep-rooted shrubs obviously were restored due to the permeability of the lake water. Species diversity existed significant difference within 500 m distance from water source,it means the water impact penetration range was less than 500m.
