【摘要】：城市土地是城市經(jīng)濟(jì)發(fā)展的最基本要素，，是社會、經(jīng)濟(jì)、文化等各種活動的載體。國民經(jīng)濟(jì)的高速增長，城市人口的快速膨脹必然導(dǎo)致對居住用地的需求量增加，給城市土地資源帶來巨大的空間和環(huán)境壓力，而我國大多數(shù)城市存量土地有限，閑置、浪費(fèi)現(xiàn)象嚴(yán)重，為緩解土地供需矛盾，滿足居民生活的多樣化需求，居住用地集約利用是我國經(jīng)濟(jì)持續(xù)發(fā)展和提高土地利用效率的必然選擇。 提高城市土地集約利用水平是滿足城市建設(shè)用地供給的重要途徑。本文以廊坊市城區(qū)2010年居住用地為研究對象，分析近年來居住用地利用情況以及存在問題：土地閑置情況較嚴(yán)重，開發(fā)住宅用地標(biāo)準(zhǔn)不合理，住宅用地利用強(qiáng)度不高，房地產(chǎn)發(fā)展持續(xù)升溫，耕地流失情況嚴(yán)重等。并在此基礎(chǔ)上以道路網(wǎng)格劃分評價單元，通過選取結(jié)構(gòu)合理度、功能平衡狀態(tài)和綜合效益狀況3個一級類指標(biāo)，以及住宅用地比例、住宅容積率、人口密度、平均樓層、住宅地價實現(xiàn)水平等13個二級類指標(biāo)，構(gòu)建評價指標(biāo)體系。基于遙感影像數(shù)據(jù)以及實地調(diào)查，利用ENVI遙感影像處理軟件和ARCGIS地理信息系統(tǒng)軟件，采用層次分析法和多因素綜合評價法測算出各個居住用地評價單元的集約度，以此劃分出從高到低的四種利用類型并從時間和空間上對評價結(jié)果進(jìn)行了詳盡的分析。對低度利用和中度利用單元進(jìn)行潛力研究，通過規(guī)劃允許容積率用地潛力測算，得出從高、中、低三種潛力類型，分析各評價單元的可挖潛數(shù)量及其分布，最后根據(jù)評價結(jié)果提出合理化建議。研究表明： 廊坊市居住用地集約利用水平較高，并且表現(xiàn)為逐年增高�？臻g差異大，特征顯著，整體集約利用水平安次區(qū)高于廣陽區(qū)；中度利用和低度利用的地塊主要分布在廊坊市步行街以北，集約利用和高度利用的地塊主要分布在市中心和鐵路沿線附近。 雖然集約利用水平較高，但仍有較大潛力空間，中度潛力區(qū)所占面積最大。并且高潛力區(qū)和中潛力區(qū)主要以低度利用類型為主，低潛力區(qū)以中度利用類型為主。居住用地面積潛力空間差異顯著，表現(xiàn)為廣陽區(qū)高于安次區(qū)，廣陽區(qū)的面積潛力單元主要分布于步行街以北，呈現(xiàn)南高北低的態(tài)勢。廊坊市居住用地整體集約度較高，但仍有較大的利用潛力；各片區(qū)居住用地集約度不同，潛力分布也有較大差異；市中心和鐵路兩側(cè)集約度高，潛力小；步行街以北集約度低，潛力大。因此，確定了廊坊市的今后發(fā)展方向，與實際相符。
[Abstract]:Urban land is the most basic element of urban economic development and the carrier of social, economic, cultural and other activities. The rapid growth of national economy and the rapid expansion of urban population will inevitably lead to the increase of demand for residential land, which will bring huge space and environmental pressure to urban land resources. However, most of the urban land stock in China is limited and idle. The phenomenon of waste is serious. In order to alleviate the contradiction between supply and demand of land and to meet the diverse needs of residents, intensive use of residential land is the inevitable choice for sustainable economic development and improving the efficiency of land use in China. Raising the level of intensive use of urban land is an important way to satisfy the supply of urban construction land. Taking the residential land of Langfang city in 2010 as the research object, this paper analyzes the situation of residential land use and the existing problems in recent years: the idle condition of land is serious, the standard of developing residential land is unreasonable, and the intensity of residential land use is not high. Real estate development continues to heat up, serious loss of cultivated land and so on. On this basis, the evaluation unit is divided by road grid. By selecting three first-class indexes, such as structural rationality, functional balance and comprehensive benefit, as well as the proportion of residential land, residential volume ratio, population density and average floor, the paper analyzes the results of this paper. The realization level of residential land price is 13 second-class indexes, and the evaluation index system is constructed. Based on remote sensing image data and field investigation, using ENVI remote sensing image processing software and ARCGIS GIS software, AHP and multi-factor comprehensive evaluation method are used to calculate the intensity of each residential land evaluation unit. Four utilization types from high to low were classified and the evaluation results were analyzed in detail in terms of time and space. In this paper, the potential of low and medium utilization units is studied. Through the calculation of the potential of land use by planning allowable volume rate, three potential types, namely high, middle and low potential, are obtained, and the number and distribution of potential of each evaluation unit are analyzed. Finally, according to the evaluation results, some reasonable suggestions are put forward. Research shows that: Langfang residential land intensive use level is high, and performance is increasing year by year. The overall intensive utilization level in Anci area is higher than that in Guangyang district, and the land plots with moderate and low utilization are mainly distributed north of pedestrian street in Langfang city. Intensive and high-use plots are mainly distributed in the city center and along the railway line. Although intensive utilization level is relatively high, there is still a large potential space, and the area of moderate potential area is the largest. The high and middle potential areas are mainly of low utilization type, and the low potential areas are mainly of moderate utilization type. The spatial difference of the potential of residential land area is significant, which shows that the area potential unit of Guangyang district is higher than that of Anci district, and the area potential unit of Guangyang district is mainly distributed north of pedestrian street, showing the trend of south high and north low. The intensity of residential land in Langfang City is high, but it still has great potential. The intensity of residential land is different and the distribution of potential is different. The intensity of urban center and railway is high, the potential is small, and the intensity of pedestrian street is low north of pedestrian street. There is great potential. Therefore, the future development direction of Langfang City is determined, which is consistent with reality.
