Abstract: Abstract: As seen through history, the construction and development of rural residential land is spontaneous, and unified scientific planning is lacking in China. In the interaction of many factors, the inflation scale of the natural rural residential land is very rapidly, and land use patterns in the rural areas are spontaneous, disorder, hollow, idle, more houses and so on. The results show that much land resources are wasted and the spatial pattern of land is seriously defaced. Consequently, the intensive use of rural residential land is the key to the construction of urban and rural integration patterns, and also is the main way to promote resource conservation and utilization. With further deepening of the regional economic and social reforms and changes of farmers′ demands, it was foreknown that rural residents' land would produce further differentiation and and require reconstruction. If appropriate intervention and effective guidance is not provided, the risk of extensive use of rural residential land would be strengthened, and intensive utilization of rural residential land would become an urgent research subject. First, according to the economics input-output theory and new rural construction requirements, this study classified the connotation and manifestation of elements of rural residential land use as two aspects, intensity and efficiency, to construct the index system of rural residential land use intensity measurement using the scale, layout, structure and production, life, and ecology efficiency as the criterion layer. Second, with the help of the decoupling principle and index deviation degree analysis method, the study established the intensity degree index model and its correction model, based on the coefficient of variation and obstruction diagnosis model, for rural residential land intensive use. The study then took the Pinggu district in Beijing, with significant suburban characteristics, as an example, and took 275 administrative villages as the basic assessment unit to assess the intensity level, divided these into different intensity modes, analyzed the intensity disturbance factors, and summed up the intensity control path. The results showed that: 1) On the whole, rural residential land use intensity level is low, the ecological and loss modes of rural residential land occupied the dominant position, the amount of excess type in intensive and extensive modes was not much, but there were significant differences between each village and town. 2) Obstacle factors of rural residential land intensive use were significant, relatively large scale and unreasonable internal structures were the main obstacles to cause higher strength of rural residential land use, and low production efficiency and poor living conditions were the factors to restrict the development of rural settlements. 3) From ecological mode to intensive mode to extensive mode to loss mode, the obstacle factors were increasing gradually. From the point of reducing the intensity of land use and enhancing the efficacy of land use, tapping potential, intensive growth, ecological balance, and sustainable development were the effective paths for different types of rural residential land. Following the complexity and particularity of rural residential land, with the element input-output theory and the decoupling theory, the study took the intensity index and efficiency index as the basis to assess the intensity level and divided the intensity mode of rural residential land. It was more comprehensive than a single index system, such as the area and population index, to reflect the rural land use characteristics. The study made theoretical connotation innovations in the aspect of rural residential land intensive use measurement, and the results were very useful in accelerating the rational use of land resources in rural areas and promoting the coordinated development of social economy and ecological environments in rural areas.
