文章摘要：城市土地利用變化及其生態(tài)環(huán)境響應(yīng)是全球環(huán)境變化研究的重要組成部分，是可持續(xù)發(fā)展研究的核心問題。大都市作為人口和產(chǎn)業(yè)密集地區(qū)，城市土地利用變化劇烈，由此帶來的生態(tài)環(huán)境問題更為顯著。在新型城鎮(zhèn)化建設(shè)背景下，研究大都市城市空間擴(kuò)展及其生態(tài)環(huán)境響應(yīng)，對(duì)提高大都市土地利用效能，轉(zhuǎn)變經(jīng)濟(jì)增長方式和實(shí)現(xiàn)可持續(xù)發(fā)展具有重要指導(dǎo)意義。文章基于北京市遙感影像數(shù)據(jù)及相關(guān)社會(huì)經(jīng)濟(jì)數(shù)據(jù)，構(gòu)建北京市空間擴(kuò)展的生態(tài)環(huán)境響應(yīng)評(píng)價(jià)指標(biāo)體系和模型，對(duì)1995─2010年北京市空間擴(kuò)展的生態(tài)環(huán)境響應(yīng)進(jìn)行了綜合評(píng)價(jià)并分析其驅(qū)動(dòng)力。研究認(rèn)為：1995─2010年北京市各區(qū)縣空間擴(kuò)展的社會(huì)經(jīng)濟(jì)壓力指數(shù)不斷增大，首都功能核心區(qū)和城市功能拓展區(qū)各區(qū)縣社會(huì)經(jīng)濟(jì)壓力指數(shù)上升幅度最大，城市發(fā)展新區(qū)和生態(tài)涵養(yǎng)發(fā)展區(qū)各區(qū)縣上升趨勢較為平緩；除東城區(qū)和西城區(qū)外，各區(qū)縣土地利用狀態(tài)指數(shù)有所下降，降低幅度較大的區(qū)縣有通州、順義、大興、平谷和昌平，較小的區(qū)縣有朝陽、海淀、豐臺(tái)、石景山和密云；除通州和大興外，各區(qū)縣空間擴(kuò)展的生態(tài)環(huán)境響應(yīng)指數(shù)均呈上升趨勢，凈變化量較大的區(qū)縣主要位于首都功能核心區(qū)，生態(tài)涵養(yǎng)區(qū)和城市發(fā)展新區(qū)各區(qū)縣凈變化量較�。怀ㄖ�、順義、延慶和昌平外，，各區(qū)縣城市空間擴(kuò)展的生態(tài)環(huán)境響應(yīng)綜合指數(shù)均有所提高，其中東城、西城、海淀和朝陽凈變化量較大，順義、平谷和懷柔凈變化量較小，空間格局表現(xiàn)出“中心低、外圍高、東南低、西北高”的特征；人口增長、城市化、經(jīng)濟(jì)發(fā)展、建設(shè)用地高速擴(kuò)展、生態(tài)用地減少等對(duì)北京城市空間擴(kuò)展的生態(tài)環(huán)境響應(yīng)具有重要影響。

Abstr：That of spatial expansion, land use change and their ecological effects is the core issue should be investigated in urban sustainable development, and moreover this is also a critical topic in global environment change. As densely populated and industrial areas, metropolis experiences dramatic land use changes and therefore significant ecological environment problems as well. Toward to China’s new urbanization, the investigation on spatial expansion and its eco-effects could significantly contribute to improve the land-use efficiency, transform the ways to achieve economic growth and finally meet sustainable development. This paper builds a comprehensive index system to evaluate eco-environment response to urban expansion, and then uses it to analyze the spatial differentiation of eco-environment response and driving forces in 16 districts in Beijing from 1995 to 2010, based on the remote sensing data and related economic-social data of Beijing. We reach five main conclusions： Firstly, the social economy pressure index to urban expansion of all 16 districts in Beijing rise during this period. The index of core urban area and urban function expansion area have largest growth, while that of new urban area and ecological conservation area have more gentle upward trend. Secondly, the land-use state index of districts except Dongcheng and Xicheng declined. The index of Tongzhou, Shunyi, Daxing, Pinggu and Changping have fast reduction, while Chaoyang, Haidian, Fengtai, Shijingshan and Miyun have slower reduction. Then the ecological environment index of districts except Tongzhou and Daxing showed an upward trend, with core urban area having largest growth and the ecological conservation areas and new urban area experienc
