中文摘要	土地生态安全是一个地区生存和发展的核心。以新疆第二大城市库尔勒市为研究靶区,运用三角模型,建立评价指标体系,通过熵权法计算各指标的权重,分别计算得到EI、NSI、NREI三组综合指数,在此基础上计算出各指标的影响度。从时间序列上对十二五规划期间内库尔勒市土地生态安全状况进行评价,并对其主要影响因子进行分析。结果表明:(1)库尔勒市土地生态安全综合指数呈现极不安全-较不安全的趋势。(2)影响库尔勒市土地生态安全的限制性因子主要是人口城市化水平、一般工业固体废物产生量以及排水管道密度。综上所述,库尔勒市土地生态安全现状极不安全,此研究将为改善生态状况提供科学依据。
英文摘要	In the arid area of northwest China, the ecological security of land has a direct impact on oasis cities whether it has the foundation to develop, sustainably in the future. Choosing the second largest city in Xinjiang, Korla City as the study area,using quantitative analysis method,and based on the economic feasibility index, non-environmental resources reasonable coefficient and non-social acceptance index, this paper built a triangle model which was further divided into five regions A-E representing the different states of land ecological security. A point in the triangle model was determined based on the values of the three complex indices,which represents the state of land ecological security of the area. And then an evaluation index system was constructed to analyze and evaluate the land ecological security state evolution and the main affecting factors in Korla City from2009 to 2014. The degree of influence of each index is calculated by normalizing the raw data with range method first, then calculating the weight of every index with entropy weight, and getting three composite index finally. The results show that during the study period, the land ecological security state in Korla City was very unsafe, since 2011,the state gradually changed to unsafe development, and this trend was stable. Therein, the economic feasibility of the index increased by 1 350%, non-social acceptability reduced by 18%,and non-resource environment rationality increased by 21%, indicating that the development of economy and society in Korla was good, but the land ecological environment worsened. According to the analysis of influencing factors,the ecology are fragile in common in oasis cities in areas, which is an inevitable issue during development. Korla City, driven by resource and industry, was developing inevitably in the mode of "pollution first,treatment later",but the rapid development of economy has led to an expansion of the built-up area, more introduction of new technologies and management model in the urban basic services, and a large number of foreign population, making the land urbanization and population urbanization gain a greater development space. Now, Korla City should improve the standard rate of industrial emissions,reasonably arrange the layout of the industrial parks and urban living areas,and further strengthen the treatment of urban life pollution to avoid the effect of peri urban agriculture,so as to ensure steady economic growth,and to provide a basis for management and ecological restoration.
