Spatial restructuring analysis of land use under planning and control of prime farmland protection area

In order to improve space guiding significance of prime farmland protection area special planning for land use, and to strengthen the land quality construction in prime farmland areas, the technical solutions of the land re-construction was explored. Taking Yangzhen town of Shunyi district as an example, according to the analysis of 12 prime farmland protection areas, the direction of regulation for farmland, rural residential land, unused land in the protected area and the spatial distribution of land readjustment and scheduling were determined by the spatial analysis function and neighborhood replacement method based on agricultural land grading results. The result showed that block area of land reclamation and regulation forⅠ, Ⅱ, Ⅲ grades were 459.44 hm2 , and adaptability evaluation of unused land at high and moderate level were 35.12 hm2, so the proportion of the arable land in the prime land protection areas could be effectively improved by regulating the section above mentioned. Meanwhile, the farmland landscape index analysis showed that the concentration degree of arable land increased continuously with plot non-arable land changing to arable land. The land use space reconstruction approach based on the behavior of land readjustment is very useful in exploring a special plan for the prime farmland area, and deepens the study of land use planning.
