In 2003, the Ministry held several major meetings, can be seen by the spirit of the meeting, state land-use macro-control has focus from a number of management to the number, quality and ecological management coordination in hand shift. Building a moderately prosperous society Outline for the Development and the 16th CPC National Congress proposed new social development planning, land management direction to reflect the change, with the implementation of social development planning, urgent need of revision, a new round of land use planning, coordination, population, resources, the harmonious development of the environment. Of geographic information system technology base, Song County as a pilot study on the quality of cultivated land-based land use planning method of preparation, a new round is about to launch a nationwide land use planning operation based on pilot experience. The paper introduces the domestic and international research in the preparation of the land use planning dynamics and significance in the country to carry out this study, and then describes the theoretical basis of the land-use planning, the revision of the guiding ideology and principles to be followed. Last Song County as an example, based on the industry of the People's Republic of China standard county-level land use planning procedures of preparation (Trial) \overall planning regulations (draft) \comprehensive analysis of the status and situation based on the quality of cultivated land, accounting the county Administrative Region of arable production capacity; intermediate results of the use of agricultural land classification, various industry sites in the full understanding of the amount of cultivated land, quality, distribution on the basis of scientific prediction; reasonable adjustments to the land use structure, and the last program summary statistics during the planning non-agricultural construction quality status of the share of arable land, for the implementation of the balance of arable land, arable land management by quantitative data provide a strong basis to the quantity, quality, ecological management; given based on the County Land quality status of basic farmland protection areas, enhance the scientific planning and operability, scientific planning only, in order to be authoritative. Main results: 1. Evaluation of land use status quo quality structural condition of the use of the MAPGIS technology cultivated land quantity, quality, and other information directly reflects the current land use map, the central control of the County Land mass distribution pattern, in order to determine the inter-regional, regional, sub- different regional quality level of arable land layout provides a multi-layered, scientific and rational basis. The Song County arable land Quality in terms of geographical distribution, Song County high-quality arable land is mainly distributed in Iraq, Ruhe and its tributaries on both sides of river in dendritic distribution, and mountain areas, shallow mountainous, hilly relatively poor quality of cultivated land. : from limiting factor of arable land, irrigation assurance, slope, soil thickness is a major limiting factor, gravel content, organic matter content, soil texture, pH values ??less limiting factor, the quality of arable land limits extracted from the property database The factors that will result in low-yielding fields improved in the future provide an important basis. (2) evaluation of the structural adjustment of land use, construction of the occupation of cultivated land quality status of arable land and do not figure to plan overlay, and to extract building occupied by the quality status of the arable land. Quantities of better planning during the occupation of arable land accounted for 73.11% of the farmland used for construction of the total nine, ten, eleven, twelve. Occupying cultivated land for non-agricultural construction quality conditions for the implementation of the balance of arable land, Dynamic Balance of Farmland data provide a strong basis.
