摘要
运用生态足迹方法探寻城市生态安全的演变特征,分析了2000-2008年丽水市快速发展时期生态足迹的构成及其动态演变规律.结果表明:2000年以来丽水市人均生态足迹呈现持续升高的态势,从0.884 hm2增至1.511 hm2,年均增幅为6.96%;人均生态承载力较为稳定,年变化率低于0.69%;2008年生态足迹多样性为0.974,生态经济发展能力为1.465 hm2,分别是2000年的1.50倍和2.56倍.说明城市化发展影响了丽水的经济结构和消费结构,不断提升的居民消费水平已经成为生态压力的主体.适度控制资源开采规模,重视生态保护和建设,进一步优化产业结构以及开发利用可再生能源是目前该类城市缓解区域生态压力的主要发展策略.
The ecological footprint and its dynamic evolution in national ecological demonstration area such as Lishui City from 2000 to 2008 were analyzed by ecological footprint method. The results showed that ecological footprint per capita in Lishui continually increased from 0.884 hm^2 to 1.511 hm^2 since 2000 with an annual average of 6.96%. The ecological carrying capacity per capita was relatively stable with an annual change rate less than 0.69%. The ecological footprint diversity was 0.974 and eco-ecohomy development capacity was 1.465 hm^2 in Lishui City in 2008, which was 1.50 and 2.56 times as much as that in 2000, showing the impact of urbanization development on its economic structrue and consumption structure. The constantly improving consumption level became a main ecological pressure. Controlling resource exploitation scale, paying more attention to ecological protection and construction, further optimizing industrial structure, developing and utilizing renewable energy should relieve regional ecological pressure.
