中文摘要	采用层次分析法(AHP)综合分析了甘肃省玛曲县湿地生态环境问题及其威胁因素.结果表明,研究区生态环境问题中,土地沙漠化问题最为突出,组合权重最大,为0.238 7;水源减少和植被退化的环境恶化程度相近,组合权重分别为0.177 2和0.144 2;气候因素中,气温的组合权重显著大于降水量.玛曲县湿地环境面临的威胁主要集中在过度放牧、资金短缺、居民受教育程度普遍偏低等方面;鼠害和沙化加速了湿地退化;虽然人口增长、旅游业发展、小城镇化扩张和道路网络密集的组合权重较小,但它们的潜在威胁很大.
英文摘要	Eco-environmental problems and threatening factors of wetlands in Maqu County, Gansu Province were analyzed with the method of analytic hierarchy process. The eco - environment problems have been divided into 4 levels and 9 factors, and the facing threatening problems have been divided into 4 levels and 16 factors. Based on the information of 117 questionnaires in the way of scoring by experts, the present eco -environment situation and the extent of threatening factors have been studied in the paper. Land desertification is the most serious eco - environment problems, its combined weight is 0. 238 7; and the next is reduction of water source and vegetation degradation, their combined weight are 0.177 2 and 0. 144 2 respectively. Among the natural factors, temperature is more significant than precipitation on climate environment. The combined weights of overgrazing, fund shortage and lower education level are bigger than those of other factors and their weights are 0. 217 5, 0. 106 3, and 0.099 5 respectively. Although the combined weights of population increase, traveling increase, urbanization speed and dense road web are smaller than those of other main factors, but their potential threats are huge.
