【摘要】："低碳"已成為全球矚目的焦點話題,成為人類社會的共識,而對于21世紀(jì)人類面臨的最為嚴(yán)峻的現(xiàn)實問題之——水資源危機,迫使人們不得不及早關(guān)注"低水"問題。人口的增長、技術(shù)的變化和消費的增加被認(rèn)為是產(chǎn)生環(huán)境危機的最主要的三個原因。當(dāng)前消費引起的環(huán)境問題卻沒有得到足夠的重視和深入的研究。經(jīng)典的IPAT建立了人文因素與環(huán)境影響間的影響關(guān)系的賬戶恒等式,通過對IPAT等式的擴展,得到分析影響可持續(xù)消費影響因素、指導(dǎo)可持續(xù)消費政策制定的IHPACT框架,并從水足跡視角,基于黑河流域張掖市水足跡調(diào)查與核算數(shù)據(jù),探討了該分析框架的可行性與必要性。研究結(jié)果表明:減少食物消費中水足跡奢侈品肉類的消費(多吃蔬菜少吃肉)可以有效地調(diào)節(jié)居民消費水足跡;消費能力的進(jìn)一步提高將增加居民消費水足跡,但以水足跡表征的環(huán)境影響與消費能力兩者間環(huán)境Kuznets曲線假說成立,即消費能力的提高最終將會降低消費的環(huán)境影響。
[Abstract]:"low carbon" has become the focus topic of global attention and the consensus of human society. However, the water resources crisis, one of the most serious practical problems facing mankind in the 21st century, has forced people to pay attention to the "low water" problem as soon as possible. Population growth, technological change and increased consumption are considered the three main causes of the environmental crisis. However, the current environmental problems caused by consumption have not been paid enough attention to and studied in depth. The classical IPAT establishes an account identity of the relationship between human factors and environmental impacts. Through the expansion of the IPAT equation, the author obtains the IHPACT framework to analyze the influencing factors of sustainable consumption and to guide the formulation of sustainable consumption policies. From the perspective of water footprint, based on the data of water footprint investigation and accounting in Zhangye City of Heihe River Basin, the feasibility and necessity of the framework are discussed. The results show that reducing the water footprint in food consumption and consuming luxury meat (eating more vegetables and less meat) can effectively regulate the water footprint of residents, and the further improvement of consumption ability will increase the water footprint of residents. However, the hypothesis of environmental Kuznets curve between environmental impact and consumption capacity represented by water footprint is established, that is, the increase of consumption capacity will ultimately reduce the environmental impact of consumption.
