【摘要】：20世紀(jì)90年代以來,生態(tài)足跡模型作為定量化可持續(xù)評(píng)價(jià)的重要理論方法得到了廣泛的應(yīng)用�；趥鹘y(tǒng)生態(tài)足跡模型,結(jié)合遙感產(chǎn)品凈初級(jí)生產(chǎn)力數(shù)據(jù),構(gòu)建了基于凈初級(jí)生產(chǎn)力的生態(tài)足跡模型,調(diào)整了均衡因子和產(chǎn)量因子,并增加了污染物賬戶。在此基礎(chǔ)上,應(yīng)用傳統(tǒng)模型和改進(jìn)后的模型分別計(jì)算了南通市2000~2013年的生態(tài)足跡。結(jié)果表明:(1)傳統(tǒng)生態(tài)足跡模型和改進(jìn)模型下的南通市2000~2013年人均生態(tài)足跡都是穩(wěn)步增長的,改進(jìn)后的模型變化較小;(2)南通市2000~2013年生態(tài)承載力雖有所波動(dòng),但整體上呈下降趨勢(shì);(3)南通市連續(xù)14年出現(xiàn)生態(tài)赤字,從2000年的0.308 6 hm~2/人上升到0.587 7 hm~2/人,生態(tài)系統(tǒng)處于不安全狀態(tài),生態(tài)系統(tǒng)的穩(wěn)定性降低。可見,改進(jìn)的生態(tài)足跡模型能更準(zhǔn)確地反映研究區(qū)自然資源利用狀況。最后,針對(duì)南通市生態(tài)不安全狀況,從土地結(jié)構(gòu)、能源消費(fèi)等方面提出減少生態(tài)足跡的建議。
[Abstract]:Since 1990's, ecological footprint model has been widely used as an important theory and method of quantitative sustainable evaluation. Based on the traditional ecological footprint model and the data of the net primary productivity of remote sensing products, the ecological footprint model based on the net primary productivity is constructed, the equilibrium factor and yield factor are adjusted, and the pollutant account is increased. On this basis, the ecological footprint of Nantong City from 2000 to 2013 was calculated by using the traditional model and the improved model respectively. The results show that both the traditional ecological footprint model and the improved model have a steady increase in the per capita ecological footprint from 2000 to 2013, and the improved model has a small change. The ecological carrying capacity of Nantong City from 2000 to 2013 fluctuates. However, the overall trend is that there is an ecological deficit in Nantong for 14 consecutive years, from 0.308 6 hm~2/ in 2000 to 0.587 7 hm~2/. The ecosystem is in an unsafe state and the stability of the ecosystem is decreased. Therefore, the improved ecological footprint model can more accurately reflect the use of natural resources in the study area. Finally, in view of the situation of ecological insecurity in Nantong City, the paper puts forward some suggestions on reducing ecological footprint from the aspects of land structure and energy consumption.
