Spatio-temporal disposition of regional land consolidation aiming at increasing agricultural integrative productivity

Taking Qingzhou County in Shandong Province as an example, index system, model and method of regional land consolidation(LC) spatio-temporal disposition aiming at increasing agricultural integrative productivity(AIP) were studied. Results indicated that the consolidation region for enhancing cultivated land AIP was 655.14 km² in the hill region, occupying 48.37% of all consolidation area, in which near LC region the northwest of the hill region, metaphase LC region occupied 19.62% in the southeast of the hill region, both giving priority to the cultivated LC, and far LC region in the southwest of the hill region, equal attention paid to cultivated LC and unused land habilitation; the un-consolidation region was cultivated land in the north plain and, occupying 51.63%. The results can provide scientific instruction for LC planning and implement at Qingzhou County.
