【摘要】：目前,我國(guó)最重要的戰(zhàn)略之一就是進(jìn)行大規(guī)模的高標(biāo)準(zhǔn)基本農(nóng)田建設(shè),2011年頒布的全國(guó)“十二五”規(guī)劃綱要明確提出要“大規(guī)模建設(shè)旱澇保收高標(biāo)準(zhǔn)農(nóng)田”,力爭(zhēng)2015年建成高標(biāo)準(zhǔn)基本農(nóng)田4億畝,2020年?duì)幦∵_(dá)到8億畝,在國(guó)家的高度重視下建設(shè)高標(biāo)準(zhǔn)基本農(nóng)田任務(wù)已在各地相繼展開。為了確保糧食安全,保護(hù)耕地的質(zhì)量,同時(shí)也是為了能夠更好地完成高標(biāo)準(zhǔn)基本農(nóng)田建設(shè)任務(wù)。學(xué)者們開始對(duì)耕地保護(hù)展開研究,而多數(shù)是對(duì)農(nóng)業(yè)產(chǎn)區(qū)的研究或者僅是對(duì)耕地質(zhì)量方面的研究,要想更快、更好地完成建設(shè)任務(wù)就要對(duì)高標(biāo)準(zhǔn)基本農(nóng)田進(jìn)行科學(xué)的劃定。都市區(qū)作為城市發(fā)展到一定時(shí)期的產(chǎn)物,它具有優(yōu)越的區(qū)位因素,同時(shí)都市區(qū)耕地也存在著被建設(shè)用地占用壓力大、占用可能性大的風(fēng)險(xiǎn),如何劃定都市區(qū)高標(biāo)準(zhǔn)基本農(nóng)田也成了完成高標(biāo)準(zhǔn)基本農(nóng)田建設(shè)任務(wù)與城市高速發(fā)展矛盾點(diǎn)所在。本論文以天津市環(huán)城四區(qū)為研究對(duì)象,一方面這四個(gè)區(qū)承載著建設(shè)高標(biāo)準(zhǔn)基本農(nóng)田的任務(wù)承載著糧食安全,生態(tài)安全等作用,另一方面這四區(qū)的土地也是天津市社會(huì)經(jīng)濟(jì)發(fā)展的一個(gè)重要平臺(tái)。所以從保護(hù)耕地多功能的角度對(duì)研究區(qū)進(jìn)行高標(biāo)準(zhǔn)基本農(nóng)田劃定的研究具有重大的戰(zhàn)略意義。通過耕地屬性界定耕地的多種功能,以天津市分等中間數(shù)據(jù)及相關(guān)數(shù)據(jù)為基礎(chǔ)建立ArcGIS數(shù)據(jù)庫(kù),選取量化因子與評(píng)價(jià)模型,通過ArcGIS的空間分析對(duì)各功能進(jìn)行評(píng)價(jià)。在此基礎(chǔ)上,分別采用逐級(jí)修正與類型組合兩種自劃定方法對(duì)研究區(qū)耕地進(jìn)行高標(biāo)準(zhǔn)農(nóng)田建設(shè)類型劃定,并將結(jié)果分為三種類型區(qū)給予建設(shè)意見,結(jié)果表明逐級(jí)修正的分區(qū)表現(xiàn)出都市區(qū)圈層分布狀態(tài),類型組合的分區(qū)結(jié)果表現(xiàn)出連片性的分布特征。
[Abstract]:At present, One of our country's most important strategies is to carry out large-scale construction of basic farmland of high standard. The outline of the "12th Five-Year Plan" issued in 2011 clearly states that "large-scale construction of high standard farmland for drought and waterlogging" should be carried out in order to be completed in 2015. High standard basic farmland 400 million mu, 2020 strive to reach 800 million mu, In order to ensure food security and protect the quality of cultivated land, the task of building high standard basic farmland has been carried out one after another under the state's high priority. Scholars have begun to study the protection of cultivated land, most of which are for agricultural production areas or only for the quality of cultivated land, if they want to do so more quickly. Better completion of the construction task requires the scientific delineation of high standard basic farmland. As a product of a certain period of urban development, metropolitan areas have superior location factors. At the same time, the cultivated land in the metropolitan area also has the risk of being occupied by the construction land under great pressure and the possibility of occupation. How to delimit the high standard basic farmland in the metropolitan area has also become the contradiction point between the task of completing the high standard basic farmland construction and the rapid development of the city. This paper takes the fourth district around the city of Tianjin as the research object. On the one hand, these four districts are carrying the task of building high standard basic farmland, bearing the role of food security, ecological security, etc. On the other hand, the land of the four districts is also an important platform for the social and economic development of Tianjin, so it is of great strategic significance to study the high standard basic farmland delineation in the research area from the angle of protecting farmland multi-function. Defining the various functions of cultivated land through the attribute of cultivated land, The ArcGIS database is established on the basis of graded intermediate data and related data in Tianjin. The quantitative factors and evaluation models are selected, and the functions are evaluated by the spatial analysis of ArcGIS. Two self-delimiting methods of stepwise correction and type combination were used to demarcate the cultivated land of high standard farmland construction in the study area, and the results were divided into three types of areas to give suggestions for construction. The results show that the modified zoning shows the distribution state of the urban circle layer, and the partition result of the type combination shows the characteristics of piecewise distribution.
