【摘要】：近年來(lái),多數(shù)城市為追求擴(kuò)大城市規(guī)模和經(jīng)濟(jì)增長(zhǎng),以犧牲耕地資源、生態(tài)用地為代價(jià)大規(guī)模擴(kuò)建新區(qū)建設(shè),引發(fā)了一系列糧食安全、征地沖突、生態(tài)破壞等問(wèn)題,土地資源的稀缺性要求城市土地利用方式從粗放轉(zhuǎn)向集約化。在一路一帶發(fā)展政策下,西安市提出“大西安”概念和“品質(zhì)西安”的新目標(biāo),這表明西安城市格局將繼續(xù)擴(kuò)大,對(duì)土地合理配置、高效利用提出了更高要求,對(duì)西安市近年的土地集約利用研究有助于從城市土地利用角度分析過(guò)去發(fā)展中存在的問(wèn)題,為今后的改革提供參考與借鑒。本文梳理了土地集約利用國(guó)內(nèi)外研究和城市土地集約利用相關(guān)理論及影響因素,為研究奠定了理論基礎(chǔ)。闡述了城市土地集約利用評(píng)價(jià)體系及選取依據(jù),通過(guò)對(duì)比分析選取PSR模型構(gòu)建本文評(píng)價(jià)體系,揭示研究區(qū)土地利用中人地相互作用的鏈?zhǔn)疥P(guān)系,采用主成分分析法確定指標(biāo)權(quán)重,使評(píng)價(jià)結(jié)果更客觀科學(xué)。以西安市土地利用現(xiàn)狀、土地利用效益為基礎(chǔ),從壓力、狀態(tài)、響應(yīng)三各子系統(tǒng)選取16個(gè)指標(biāo)構(gòu)建PSR評(píng)價(jià)指標(biāo)體系,經(jīng)過(guò)綜合計(jì)算后分析西安市土地集約利用水平及協(xié)調(diào)度情況。通過(guò)橫向?qū)Ρ?顯示西安市在全國(guó)十五個(gè)副省級(jí)市中,土地集約利用水平屬于一般集約度,與東南沿海地區(qū)的廣州、深圳、杭州等城市相比存在明顯差距。研究結(jié)果表明:(1)西安市土地集約利用水平2006年至2014年逐年上升,分為快速上升期和緩慢增長(zhǎng)期。受壓力層的影響,狀態(tài)層變化最復(fù)雜,經(jīng)歷了快速上升、回落、緩慢上升的過(guò)程,響應(yīng)系統(tǒng)變化浮動(dòng)較小,整體趨勢(shì)較為平穩(wěn),但三個(gè)子系統(tǒng)協(xié)調(diào)狀態(tài)不佳,在一定程度上說(shuō)明西安市面對(duì)土地集約利用的壓力、狀態(tài)沒(méi)有快速反應(yīng)。(2)通過(guò)橫向?qū)Ρ?西安市土地集約利用水平在15個(gè)副省級(jí)城市行列中排名第12位,處于中游偏下一般集約水平,在因子得分中,最高分是土地投入因子,最低分是土地利用因子。通過(guò)因子分析結(jié)果與其它排名前十的城市相比,存在顯著差距。(3)綜合西安市土地集約利用水平和城市對(duì)比差距,提出通過(guò)產(chǎn)業(yè)優(yōu)化整合、存量帶增量、開(kāi)發(fā)地下空間、應(yīng)用信息技術(shù)等綜合性措施使西安市土地集約達(dá)到更高水平。
[Abstract]:In recent years, in order to expand the urban scale and economic growth, most cities expand the new area at the expense of cultivated land resources and ecological land, causing a series of problems such as food security, land expropriation conflicts, ecological destruction, and so on. The scarcity of land resources requires the transformation of urban land use from extensive to intensive. Under the Belt and Road development policy, Xi'an puts forward the concept of "great Xi'an" and the new goal of "quality Xi'an", which indicates that Xi'an will continue to expand its urban structure and put forward higher requirements for rational land allocation and efficient utilization. The study of intensive land use in Xi'an in recent years is helpful to analyze the problems existing in the past development from the perspective of urban land use, and to provide reference and reference for the future reform. This paper combs the relevant theories and influencing factors of intensive use of land at home and abroad and urban land intensive use, which lays a theoretical foundation for the research. This paper expounds the evaluation system of urban land intensive use and the basis of selection. Through comparative analysis, the PSR model is selected to construct the evaluation system of this paper, and the chain relationship of human-land interaction in land use in the study area is revealed. The principal component analysis method is used to determine the index weight, which makes the evaluation result more objective and scientific. Based on the present situation of land use and benefit of land use in Xi'an, 16 indexes are selected to construct the PSR evaluation index system from the aspects of pressure, state and response. After comprehensive calculation, the intensive use level and coordination degree of Xi'an land were analyzed. Through the horizontal comparison, it is shown that the intensive land use level of Xi'an belongs to the general intensive degree in the fifteen sub-provincial cities of China, and there is a significant gap between Xi'an and Guangzhou, Shenzhen, Hangzhou and other cities in the southeast coastal area. The results showed that: (1) from 2006 to 2014, the intensive land use level in Xi'an increased year by year, which was divided into fast rising period and slow increasing period. Under the influence of pressure layer, the change of state layer is the most complex, and it has experienced the process of rapid rise, fall down, slow rise. The response system fluctuates little, the overall trend is relatively stable, but the coordination state of the three subsystems is not good. To a certain extent, Xi'an does not respond quickly to the pressure of intensive land use. (2) through horizontal comparison, Xi'an land intensive use level ranks 12th among the ranks of 15 sub-provincial cities. In the middle level, the highest score is the land input factor and the lowest score is the land use factor. There is a significant gap between the results of factor analysis and other top 10 cities. (3) according to the land intensive utilization level of Xi'an city and the contrast gap between cities, the paper puts forward the development of underground space through industrial optimization and integration, the increment of stock belt, and the development of underground space. Application of information technology and other comprehensive measures to make Xi'an land intensive to a higher level.
