基于能值-生态足迹模型的齐齐哈尔市可持续发展水平分析

SUSTAINABLE DEVELOPMENT LEVEL OF QIQIHAER BASED ON ENERGY-ECOLOGICAL FOOTPRINT MODEL

基于能值理论,运用生态足迹模型,对齐齐哈尔市2000-2016年能值生态承载力、能值生态足迹和生态赤字/盈余等指数进行了定量计算和分析。结果表明:研究期间,齐齐哈尔市处于生态赤字状态,且生态赤字增加趋势明显即本地区人类对于资源的需求量已超过自然环境的供给量,生态环境处于不可持续的发展状态;研究区生态环境承载的压力呈增长的趋势;经济社会发展状况与生态环境的协调性呈减弱的趋势,区域生态协调性较差;由万元GDP生态足迹指数可知,齐齐哈尔市在经济社会发展的进程中,能源利用率有所提高,资源利用方式有所改善,经济发展造成的生态代价在逐渐减小。

This paper, based on energy values theory, uses ecological footprint model to quantitatively analyze Qiqihaer’s energy ecological carrying capacity, energy ecological footprint and ecological deficit/excess during 2000 to 2016, with results showing that Qiqihaer had been in ecological deficit at a rising tendency, which means human’s demands exceed the natural supplies, an unsustainable status. Qiqihaer shows a growing ecological environmental carrying capacity pressure, a diminishing coordinated ecology and eco-environment. The regional ecological coordination is relatively poor. GDP ecological footprint index per 10 k RMB indicates an increasing energy use rate, an improved resource use method and a decreasing ecological impact during Qiqihaer’s economic development.
