【摘要】：中國的“高能耗、高污染、高排放”發(fā)展模式,所產(chǎn)生的生態(tài)環(huán)境與生態(tài)壓力問題廣為人們所“詬病”。當(dāng)前,在我國快速城市化進(jìn)程中,城市空間的快速擴(kuò)張必然對(duì)區(qū)域的經(jīng)濟(jì)活動(dòng)、文化與社會(huì)意識(shí)、土地利用變化、生態(tài)環(huán)境保護(hù)等產(chǎn)生深刻影響,并導(dǎo)致區(qū)域碳排放與碳足跡的特征與空間格局產(chǎn)生變化。研究城市空間擴(kuò)張與碳足跡的相互作用關(guān)系、響應(yīng)機(jī)理、反饋過程,對(duì)加深城市化與低碳發(fā)展的地理—生態(tài)過程及效應(yīng)機(jī)制的認(rèn)識(shí)具有積極作用,對(duì)科學(xué)指導(dǎo)和管控城市空間增長(zhǎng)以及發(fā)展空間低碳化模式具有重要的意義。 本文結(jié)合RS和GIS技術(shù),基于城市空間增長(zhǎng)過程的視角,研究西安城市碳足跡的時(shí)空演變特征與其生態(tài)效應(yīng),總結(jié)梳理城市空間增長(zhǎng)與城市碳足跡的反饋、調(diào)控過程,在此基礎(chǔ)上提出西安城市空間增長(zhǎng)的低碳化模式與相應(yīng)的調(diào)控措施。研究結(jié)論主要包括： (1)西安土地利用時(shí)空變化特征。城鎮(zhèn)用地增加明顯；林地面積與牧草地面積持續(xù)減��；園地面積增加；耕地面積呈持續(xù)減小趨勢(shì)；水域面積先減小后增加；未利用地比重持續(xù)減少。 (2)西安城市碳足跡時(shí)空變化特征。1999-2011西安市碳足跡總量呈波動(dòng)增長(zhǎng)趨勢(shì),平均增速為1.50%；1999年、2004年以及2009年是碳足跡發(fā)生明顯增加的年份,遠(yuǎn)遠(yuǎn)高于平均增速。2000-2011年西安城市建成區(qū)面積與碳足跡總量的存在顯著相關(guān)性�？臻g上,碳足跡呈現(xiàn)顯著的區(qū)域差異。 (3)2010年西安市城區(qū)的碳足跡特征。①西安市城區(qū)碳足跡差異大,碳足跡灞橋區(qū)蓮湖區(qū)新城區(qū)雁塔區(qū)未央?yún)^(qū)碑林區(qū)。②西安市城區(qū)各街道碳足跡呈現(xiàn)三個(gè)高值區(qū)的空間分布特征,且區(qū)域差異明顯。 (4)雁塔區(qū)碳足跡特征。無論是能源利用碳排放總量還是碳足跡都穩(wěn)居榜首。影響因素有工業(yè)園區(qū)、房地產(chǎn)產(chǎn)業(yè)以及經(jīng)濟(jì)圈的快速發(fā)展、能源利用技術(shù)和新能源的開發(fā)狀況與經(jīng)濟(jì)發(fā)展速度相比相對(duì)落后、能源結(jié)構(gòu)仍然以煤炭和石油等傳統(tǒng)的高碳排化石能源為主體。因此,可通過發(fā)展低碳經(jīng)濟(jì),調(diào)整產(chǎn)業(yè)結(jié)構(gòu),改善能源利用結(jié)構(gòu),提高能源利用效率,開發(fā)利用清潔能源,控制房地產(chǎn)業(yè)開發(fā)力度。 (5)西安城市碳足跡時(shí)空變化的生態(tài)效應(yīng)評(píng)價(jià)。西安各區(qū)縣能源利用的碳足跡產(chǎn)值變化均呈逐年增加態(tài)勢(shì)。2008年西安的能源利用的碳足跡產(chǎn)值為9.74萬元／hm2,比2005年的4.94萬元／hm2增加了4.20萬元／hm2,年均增長(zhǎng)率為28.00%,是2005年的1.85倍。2011年西安的能源利用的碳足跡產(chǎn)值14.02萬元／hm2比2005年增加了4.88萬元／hm2,年均增長(zhǎng)率約為17.81%,為2008年的1.53倍,是2005年的2.84倍。各區(qū)縣能源利用的碳足跡強(qiáng)度的變化均呈逐年減小態(tài)勢(shì)。 (6)城市空間增長(zhǎng)與碳足跡的動(dòng)態(tài)響應(yīng)與反饋機(jī)制,主要體現(xiàn)在城市空間與增長(zhǎng)所承載的產(chǎn)業(yè)活動(dòng)與土地利用方式與碳排放之間的變化關(guān)系方面。西安城市空間的低碳化增長(zhǎng)與管理調(diào)控,應(yīng)側(cè)重對(duì)產(chǎn)業(yè)活動(dòng)與土地利用的低碳管理方面。
[Abstract]:Chinese "high energy consumption, high pollution and high emission" mode of development, ecological environment and ecological pressure generated by the widely criticized. At present, in the city of rapid urbanization in China in the process of the rapid expansion of the city space of regional economic activity, culture and social consciousness, land use change and have a profound impact on the protection of the ecological environment, and lead to the characteristics and spatial pattern of regional carbon emission and carbon footprint of the change. The interaction between research, city spatial expansion and the carbon footprint of the response mechanism of the feedback process, plays a positive role in understanding the mechanism of geographical ecological processes and effects to enhance city urbanization and low-carbon development. That has important significance for scientific guidance and control of city space growth and development space of low-carbon mode.
This combination of RS and GIS technology, the city space growth process based on the perspective of the evolution, characteristics and ecological effects of space on Xi'an city's carbon footprint, feedback, control process of summarizing the city space growth and the carbon footprint of the city, on the basis of Xi'an city space growth low-carbon mode and the corresponding control measures. The main conclusions of the study including:
(1) the temporal and spatial change characteristics of land use in Xi'an. The increase of urban land is obvious. The area of forestland and the area of forage grass continue to decrease. The area of garden increases, the area of arable land keeps decreasing, the area of water area decreases first and then increases, and the proportion of unused land decreases.
(2) the total carbon footprint of Xi'an City carbon footprint of temporal and spatial variation characteristics of.1999-2011 in Xi'an city is a growing trend of fluctuations, the average growth rate of 1.50%; 1999, 2004 and 2009 are significantly increased the carbon footprint of the year, far higher than the average growth rate of.2000-2011 in Xi'an City area and the total carbon footprint was significant. Space, carbon footprint is significant regional differences.
(3) the carbon footprint characteristics in Xi'an city in 2010. The difference of carbon footprint in Xi'an City, Weiyang District Beilin District carbon footprint of Baqiao District Lianhu District new town of Yanta District of Xi'an city streets. The carbon footprint has three high value distribution space, and obvious regional differences.
(4) Yanta District carbon footprint characteristics. Both energy carbon emissions and carbon footprint are ranked top. Influence factors of the industrial park, the rapid development of the real estate industry and the economic circle, energy utilization and economy development speed and development status of technology and new energy in the energy structure is still relatively backward, with coal and oil etc. the traditional high carbon fossil energy as the main body. Therefore, the development of low-carbon economy, adjust the industrial structure, improve energy structure, improve energy efficiency, development and utilization of clean energy, control of real estate development efforts.
(5) the evaluation of ecological effect in Xi'an city. The spatial variation of the carbon footprint of the output value of the carbon footprint of energy use changes in all districts and counties of Xi'an were increased year by year the output value of the carbon footprint in Xi'an energy utilization situation of.2008 is 97 thousand and 400 yuan / Hm2, than in 2005 of 49 thousand and 400 yuan / hm2 increased 42 thousand yuan / hm2, the average annual growth rate of 28% that is 1.85 times in 2005 in Xi'an.2011 energy carbon footprint output value of 140 thousand and 200 yuan / hm2 than in 2005 increased by 48 thousand and 800 yuan / hm2, the average annual growth rate of about 17.81%, 1.53 times in 2008, 2.84 times in 2005. The county changes in energy utilization of carbon footprint intensity showed a decreasing trend.
(6) the dynamic response and feedback mechanism of city space growth and carbon footprint, mainly carrying in the city space and the growth of industrial activity and the relationship between land use change and carbon emissions. Low carbon growth and management regulation of Xi'an city space, should focus on industrial activity and land use low carbon management.
