摘要
生态足迹是衡量一个国家或地区可持续发展程度的一种方法,可定量反映人类活动对生态环境的影响和破坏程度。利用生态足迹模型,采用多源数据,以福州市经济技术开发区为例,评价人类活动对其生态环境的影响作用。分别计算了流域生态足迹、生态承载力、生态赤字以及万元GDP生态足迹,并分析其生态安全。结果表明生态足迹不断增加,且渐高于当地的生态承载力,呈现赤字,同时生态压力处于不安全状况,生态经济协调性差,生态环境处于不平衡状态,说明现有的可持续发展模式面临考验,社会经济与生态环境承受力不相协调。对此,提出了有利于该区生态、经济、环境协调发展的具体生态恢复对策和措施。
Ecological Footprint is the method measuring the sustainable development of a country or a region that quantitatively reflect the impact of human activities on nature. Based on ecological footprint model, by using Fuzhou Economic and Technological Development Zone as an example, the assessment of human activities on the ecological environment impact was conducted with the multi - source data. It is calculated the ecological footprint, ecological carrying capacity, ecological deficit and ten thousand GDP ecological footprint for the analysis of the ecological security. The statistical data analysis and calculations show that with the increase of the ecological footprint, that gradually excess the ecological carrying capacity and appears the ecological deficits. The simultaneous ecological pressure is in the unsafe state with the poor eco - economy harmony. The ecological environment is in an unbalanced state means that the sustainable development model at the moment would face the test. Therefore, it is raised the counterpart measures favorable to the harmonious development of ecology, economy and environment of the area.
