中文摘要	玛纳斯河流域是中国干旱区最具代表性的山地-绿洲-荒漠生态系统,三大生态系统表现出的区域生态、经济要素的空间状况有所分异,所存在的生态安全问题的表现形式也各不相同。根据流域土地利用和水资源数据库,在生态经济功能分区的基础上,针对流域不同分区存在的生态安全问题,选取相应的17个生态风险评估指标,建立了生态-经济风险性评价模型,对流域各个生态经济功能亚区的生态问题潜在的风险性进行了生态风险评估。结果表明:Ⅰ_1,Ⅱ_1,Ⅱ_2,Ⅱ_3,Ⅲ_1,Ⅲ_2和Ⅲ_3亚区的生态问题潜在的风险性在增大,说明生态问题日益突出,而Ⅰ_1和Ⅱ_4亚区生态问题潜在的风险性指数存在波动;Ⅰ,Ⅱ和Ⅲ三个大区中生态问题潜在的风险性指数最高的分别是Ⅰ_1,Ⅱ_1和Ⅲ_1亚区。评价结果能够较为客观地反映了当地的实际情况,因而对流域可能出现的灾害性的环境问题及由此引起的巨大的经济损失提出了警示。
英文摘要	Manas River Basin is one of the most representative mountain-oasis-desert ecosystems in arid region of China.There are some differences between the spatial status of regional ecology and economy of the three ecosystems,i.e.mountain ecosystem,oasis ecosystems and desert ecosystem.Thus,the representations of eco-economic security problems are different.Based on subdivided eco-economic functional regions,and make use of the land-use and water resource database of the basin,this paper established the ecological and economic risk assessment model by 17 ecological risk assessment indices and assessed the potential risk of the ecological problems with different subdivided eco-economic functional regions,The results indicate that the risk of ecological problems in the sub-regions Ⅰ_1,Ⅱ_1,Ⅱ_2,Ⅱ_3,Ⅲ_1,Ⅲ_2 and Ⅲ_3 is increasing from 1997 to 2007,which suggests the ecological problems become increasingly prominent,and the risk exponents of sub-regions Ⅰ_1 and Ⅱ_4 are fluctuated from 1997 to 2007.The result also shows the top ecological potential risk exponents in the three region Ⅰ,Ⅱ and Ⅲ are in sub-regions Ⅰ_1,Ⅱ_1 and Ⅲ_1,respectively.The assessment results can reflect the actual state objectively,therefore,it brings forward a caution in the occurrence of calamitous environmental issues and a huge economical loss resulting from the environment issues.
