Abstract: Improving land quality is one of the important aims of farmland consolidation.It is the basis for regional farmland consolidation planning to evaluate consolidation grades of land quality and to determine regional spatio-temporal collocation,based on the impacts of land consolidation on land quality.Taking Qingzhou County of Shandong Province as an example,this paper established the quality evaluation index system and evaluation model for farmland consolidation,based on the systematical analysis of land consolidation characteristics and natural and social conditions in Qingzhou County.The integrated score of every evaluation unit was calculated by the method of integrated index evaluation and GIS techniques,and spatio-temporal collocation of regional farmland consolidation was proposed accordingly.The results indicated that the first class land consolidated area was 106.21km2,occupied 8.85% of the total consoli-dated area,distributing in the eastern plain of Qingzhou County;the second class area was 234.04km2,occupied 19.51% of the total area,distributing in the central plain and the western hilly region;the third class area was 559.36km2,occupied 46.63%,distributing in the western plain and central hilly region;and the fourth class,25.01% of the total area,distributing in the northern plain and the southern hilly region.The results will provide scientific basis for land consolidation planning and implementing in Qingzhou County.
