Based on the theory of man-land relationship area system, following the research ideas, which were factors to express the feature and features to group the type and types to guide the models and models to improve factors, the social economic factors and natural environment factors of rural settlement were defined clearly. The characteristics of the inequality of rural industry-labor structure, the livability of rural living environment and the intensity of rural residential land were analyzed quantitatively by the coordination coefficient model and multifactor comprehensive evaluation method. Qualitative coupling method of elements and characteristics were used to classify the rural settlements as eight types in the same county, and eleven rural residential consolidation models were proposed from the three aspects of resources allocation, structure optimization and space reconstruction in the light of the limiting factors of different rural settlement type. The empirical results show that the difference is significant in the aspect of rural settlements elements and regional characteristics in Pinggu district, Beijing. There are more restrictive factors for rural residential area sustainable utilization. 55.64% villages are imbalance in the aspect of industry-labor structure, 52% villages are unfavorable relatively in the aspect of housing conditions, 44.36% villages are less intensive in the aspect of land use, and the formation of the imbalance-not livable-height intensity is too much in the whole region. Single factor special consolidation and multi-factor comprehensive consolidation, which include upgrading of rural industrial structure, transferring of surplus labor force, renewal and reorganization of rural living environment factors, reconstruction of the urban and rural system and spatial agglomeration, are the core contents of rural residential land consolidation and rich and beautiful countryside construction.

Firstly, according to the spatial-temporal characteristics of rural residential land consolidation, in order to guide the multiple target of rural residential land consolidation, the influence factors of different goals are classified as two aspects, which are urgency and suitability of rural residential land consolidation. Secondly, with the comprehensive evaluation of rural residential land consolidation urgency-suitability degree and construction of exclusive matrix combining method, the authors list the different target scheduling of rural residential land consolidation and establish the spatial organization and allocation pattern under the guidance of multiple target. The case study in Pinggu district in Beijing show that time urgency of rural residential land consolidation is divided into four grades, high, moderate, low and no urgency, and the proportions of village number are 12.73%, 28.36%, 24.73% and 34.18% accordingly. Characteristics of special distribution is urgency level from high to low layer structure. Space suitability of rural residential land consolidation is divided into four grades, high, moderate, low and no suitability, and the proportions of village number are 11.27%, 33.09%, 36.73% and 18.91% accordingly. There is obvious group layer structure in special distribution of village. Combining with urgency and suitability level results, the spatial-temporal collocation pattern for rural residential consolidation land is formatted, which are the priority areas in the near future, the key areas in the medium term, the suitable areas in the long term and limiting consolidate. The goal orientation and safeguard measures in different areas of rural residential land consolidation has also been put forward.
