【摘要】：經(jīng)濟的快速發(fā)展和工業(yè)化進程的加快，勢必占據(jù)原本就有限的耕地資源，加上我國人口眾多，人均耕地少，耕地資源更要加以保護。為了提高農(nóng)業(yè)的生產(chǎn)能力，使有效耕地面積增加，達到耕地總量的動態(tài)平衡，從2011年開始，新一輪土地整治工作在我國全面展開。 在土地整治工作中，既要增加耕地的數(shù)量又要提高耕地的質(zhì)量，而土地的適宜性評價正是確定土地是否適宜某種土地利用類型、提高耕地質(zhì)量的有效手段，所以作為土地整治工作中的一項重要內(nèi)容，，土地適宜性評價的方法也被越來越多的學者所關注。本文在總結現(xiàn)有的土地適宜性評價的方法之上，分析其優(yōu)缺點，以土地整治規(guī)劃的相關文件為標準，選取耕地和農(nóng)村建設用地為研究對象，按功能將耕地整理類型劃分為土地平整整理（包括坡改梯整理和格田整理）、農(nóng)田水利工程整理、農(nóng)村道路整理，以及針對農(nóng)村居民點的農(nóng)村建設用地整理。針對每種土地整理類型分別構建適宜性評價指標體系，建立適用于土地整治規(guī)劃的適宜性評價方法。在數(shù)據(jù)的組織和分析處理上，主要采用GIS的方法，運用GIS強大的數(shù)據(jù)組織、數(shù)據(jù)處理和空間分析功能，來實現(xiàn)數(shù)據(jù)的管理和整個適宜性評價過程。 研究工作以鹽亭縣為實證研究的對象，以行政村為評價單元，對耕地和農(nóng)村建設用地進行土地整治中的適宜性評價，分別得到每種整理類型的重點整理區(qū)，它們依次為土地平整重點整理區(qū)（包括坡改梯重點整理區(qū)和格田重點整理區(qū)）、農(nóng)田水利工程重點整理區(qū)、農(nóng)村道路重點整理區(qū)和農(nóng)村建設用地重點整理區(qū)。通過實地調(diào)研，評價結果和實際情況能夠比較好地吻合，說明本次適宜性評價方法能夠適用于土地整治規(guī)劃中，為土地整治中適宜性的評價提供了一種參考。
[Abstract]:The rapid development of economy and the acceleration of industrialization are bound to occupy the original limited cultivated land resources, plus our country has a large population, the per capita arable land is less, the cultivated land resources should be protected. In order to improve the agricultural production capacity, increase the effective cultivated land area and achieve the dynamic balance of the total cultivated land amount, a new round of land renovation work has been carried out in our country since 2011. In the process of land regulation, it is necessary to increase the quantity of cultivated land and to improve the quality of cultivated land, and the evaluation of land suitability is an effective means to determine whether land is suitable for a certain type of land use and to improve the quality of cultivated land. Therefore, as an important part of land regulation, the method of land suitability evaluation has been paid more and more attention by more and more scholars. On the basis of summarizing the existing methods of land suitability evaluation and analyzing its advantages and disadvantages, this paper selects cultivated land and rural construction land as the research object, taking the relevant documents of land renovation planning as the standard. According to the function, the types of arable land consolidation are divided into land leveling and consolidation (including sloping and terrace consolidation and grid land consolidation), farmland and water conservancy engineering consolidation, rural road consolidation, and rural construction land consolidation for rural residential areas. According to each land consolidation type, the suitability evaluation index system is constructed, and the suitability evaluation method suitable for land regulation planning is established. In the aspect of data organization and analysis, the method of GIS and the powerful functions of data organization, data processing and spatial analysis of GIS are used to realize the management of data and the whole process of suitability evaluation. Taking Yanting County as the empirical research object and administrative village as the evaluation unit, the paper evaluates the suitability of cultivated land and rural construction land, and obtains the key consolidation areas of each sort of consolidation. They are: land leveling key consolidation area (including slope and ladder key consolidation area and grid farmland key finishing area), farmland water conservancy project key consolidation area, rural road key consolidation area and rural construction land consolidation area. Through the field investigation, the evaluation results and the actual situation can be well consistent, which shows that the suitability evaluation method can be used in the land regulation planning, and provides a reference for the suitability evaluation in the land regulation.
