【摘要】：合理利用資源、保護(hù)生態(tài)環(huán)境,實(shí)現(xiàn)我國經(jīng)濟(jì)與資源環(huán)境的協(xié)調(diào)發(fā)展,是當(dāng)前發(fā)展階段我們必須要解決的問題。要做到經(jīng)濟(jì)資源的合理利用以及可持續(xù)發(fā)展,我們必須要對自身的生態(tài)狀況有著清楚地認(rèn)識和了解,所以對生態(tài)狀況的定量分析就成為了我們關(guān)注以及研究的焦點(diǎn)。生態(tài)足跡模型是定量評價生態(tài)狀況和可持續(xù)發(fā)展能力的重要模型,自問世以來得到了廣泛應(yīng)用。但在實(shí)際應(yīng)用過程中,也存在著缺乏代表性、賬戶不完善等諸多問題。為了能夠讓生態(tài)足跡模型的測量結(jié)果能夠更為準(zhǔn)確的描述和反應(yīng)我國的生態(tài)狀況,本文通過引用“國家公頃”概念,增加污染物賬戶和水資源賬戶對傳統(tǒng)生態(tài)足跡模型進(jìn)行改進(jìn),并以甘肅省為例,對其2006-2012年間的生態(tài)狀況進(jìn)行了測算和分析。并在此基礎(chǔ)上對甘肅省2006-2012年間生態(tài)狀況及可持續(xù)發(fā)展?fàn)顩r進(jìn)行了評價。歸納得出如下結(jié)論:(1)從生態(tài)盈余/赤字上看,由于經(jīng)濟(jì)的迅速發(fā)展,資源需求的不斷加大,導(dǎo)致甘肅省在2006-2012年期間,總生態(tài)足跡和人均生態(tài)足跡均在不斷上升,而同期由于生態(tài)承載力和人均生態(tài)承載力的下降,導(dǎo)致甘肅省2006-2012年的生態(tài)環(huán)境不斷惡化。(2)從分類結(jié)構(gòu)上看,甘肅省在2006-2012年期間,人均生態(tài)足跡最大的是耕地,高于其他類型的生物生產(chǎn)性土地,但由于其整體變化比較平穩(wěn),在這期間直接影響著人均生態(tài)足跡的變化趨勢的是化石能源用地的生態(tài)足跡。而對于人均生態(tài)承載力,由于甘肅省近年來耕地資源壓力的不斷增大,其對甘肅省近年來人均生態(tài)承載力的不斷惡化貢獻(xiàn)最大。(3)萬元GDP生態(tài)足跡在2006-2012年期間呈下降趨勢,這說明甘肅省近年來經(jīng)濟(jì)在快速發(fā)展,GDP的增長幅度大于生態(tài)足跡的增長幅度。(4)通過對甘肅省生態(tài)足跡多樣性指數(shù)的發(fā)展趨勢觀察,發(fā)現(xiàn)甘肅省生態(tài)足跡多樣性指數(shù)有遞減趨勢,表明甘肅省各類土地的利用類型越來越不均衡。此外通過對甘肅省發(fā)展能力指數(shù)的發(fā)展趨勢觀察,發(fā)現(xiàn)甘肅省的生態(tài)經(jīng)濟(jì)系統(tǒng)發(fā)展能力由于近幾年生態(tài)足跡的不斷增加整體上也呈略微上升趨勢。
[Abstract]:Rational utilization of resources, protection of ecological environment, and coordinated development of our economy and resources and environment are the problems we must solve at the present stage of development, so as to achieve rational utilization of economic resources and sustainable development. We must have a clear understanding of our own ecological situation. Therefore, the quantitative analysis of ecological status has become the focus of our attention and research. Ecological footprint model is an important model for quantitative evaluation of ecological status and sustainable development ability. It has been widely used since it came out, but in the process of practical application, there is also a lack of representativeness. In order to make the measurement results of ecological footprint model more accurate to describe and reflect the ecological situation in China, this paper cites the concept of "national hectare". Adding pollutant accounts and water resources accounts to improve the traditional ecological footprint model, and taking Gansu Province as an example. The ecological status of Gansu Province from 2006 to 2012 was measured and analyzed, and the ecological status and sustainable development of Gansu Province from 2006 to 2012 were evaluated. The conclusions are as follows:. (. 1) from the perspective of ecological surplus / deficit. Due to the rapid development of economy and the increasing demand for resources, the total ecological footprint and the per capita ecological footprint of Gansu Province are rising in 2006-2012. The decline of ecological carrying capacity and per capita ecological carrying capacity in the same period led to the deterioration of ecological environment in Gansu Province from 2006 to 2012. Between 2006 and 2012, the largest ecological footprint per capita in Gansu Province is cultivated land, which is higher than other types of biological productive land, but its overall change is relatively stable. During this period, it is the ecological footprint of fossil energy land that has a direct impact on the change trend of per capita ecological footprint. However, for the ecological carrying capacity per capita, the pressure of cultivated land resources in Gansu Province has been increasing in recent years. In recent years, its contribution to the deterioration of ecological carrying capacity per capita in Gansu Province is the largest. (3) the ecological footprint of RMB 10,000 yuan (GDP) showed a downward trend during the period of 2006-2012. This shows that the rapid economic development in Gansu Province in recent years the GDP growth range is larger than the ecological footprint growth range. 4) through the Gansu Province ecological footprint diversity index development trend observation. It is found that the diversity index of ecological footprint in Gansu Province has a decreasing trend, which indicates that the land use types in Gansu Province are becoming more and more unbalanced. In addition, the development trend of the development ability index of Gansu Province is observed. It is found that the development ability of ecological economic system in Gansu Province has a slight upward trend as a whole due to the increasing ecological footprint in recent years.
