摘要 小城镇生态安全是区域乃至国家生态安全的重要组成部分。本文以西安市小城镇为研究对象,结合当地自然环境特征与经济发展水平,依据"压力—状态—响应"模型构建评价指标体系,量化评价了小城镇生态安全状态,揭示了小城镇生态安全地理分布规律,提出了基于生态安全的小城镇发展建议,为确保小城镇建设与生态环境相适宜提供评价方法与科学依据。结果表明,西安市小城镇总体处于临界安全状态,且小城镇生态安全与地形地貌存在耦合性,其生态安全指数总体呈现自山地、台塬、丘陵、平原渐次递减规律。 Ecological security of town is the main component of regional and even national ecological security.This paper,taking towns in Xi'an as the research area,combined with the feature of the local natural environment and economic development level,according to"pressure-state-response"model to build the assessment index system,the quantitative assessment of ecological security status of towns,to reveal the geographical distribution of ecological security of towns,to propose towns development proposals based on ecological security,to ensure the construction of towns and ecological environment is suitable to provide assessment method and scientific basis.The research results shown that towns in Xi'an are totally in a state of critical security,and there is a coupling between the ecological security of towns and the landform,the general ecological security index decreases from mountains,tablelands,hills to plains.
