基于生态足迹的城市生态安全评价 -以宝鸡市为例

摘要：【研究目的】：分析宝鸡市生态安全与社会经济发展存在的问题及对策，以期为相关决策部门提供参考依据；【方法】以生态足迹分析方法为基础，利用生态压力指数对宝鸡市1996-2005年的生态安全进行初步研究和评价；【结果】宝鸡市的生态压力指数从1996年的1.453041逐年增至2005年的4.452437，增加了3.06倍，生态足迹与生态承载力之间的矛盾正在加剧，生态系统进一步遭到破坏，人地关系紧张，现有的发展模式是不可持续的，生态环境由较不安全变为极不安全状态；【结论】评价结果显示，宝鸡市近十年来的自然生态由较不安全状态变为极不安全状态，且生态压力指数呈上升趋势。
