摘 要：
本文基于S-PRD模型,以水、大气、土地、生物子系统为基础,建立延吉市城市自然生态安全评价指标体系,运用UNES指数法和灰色关联度分析法对延吉市2006—2013年的自然生态安全状况进行评价并探讨期间影响延吉市自然生态不安全状态产生的主导因素。结果表明:延吉市自然生态安全状况整体上在不断改善;研究期间影响延吉市综合生态不安全状态产生的主导因素是调控;在各子系统中,影响延吉市生态不安全状态产生的具体要素是水系统中的压力、大气系统中的调控、土地系统中的调控和生物系统中的压力。该研究可为延吉市未来生态环境质量的改善和生态安全规划管理提供理论依据。

摘 要：
This paper was based on the S-PRD model and the urban natural ecological security evaluation index system of Yanji city was established which was based on water,atmosphere,land and biological subsystem.This paper used the UNES index method and gray correlation degree analysis method to evaluate the natural ecological security status of Yanji city in the year 2006-2013 and discussed the dominant factor which affected the natural ecological insecurity of Yanji City.The results showed that the overall natural ecological security situation of Yanji city was in a continuous improvement.During the study period,the dominant factor which affected the comprehensive ecological insecurity of Yanji City was regulated and controlled.Furthermore,the specific elements which affected the ecological insecurity of Yanji City in each subsystem was the pressure of water system、regulation of atmospheric system、regulation of land system、pressure of biological systems.This study provided a theoretical basis for the improvement of ecological environment quality in Yanji and ecological safety planning and management in the future.
