近年来，人口行为研究备受关注，人口分布、人口调控、城市融入、农村建设、农户行为、农户生计等领域均取得显著进展。由于缺乏社区微型调查，人口地理学家对社区和家庭尺度的人口行为背后的生活逻辑尚缺乏跨尺度的体验、理解和感悟，制约了人口地理学的理论创新。项目以泥河湾盆地衰落农村为例，以社区（村）为单位，结合多维地理要素，划分社区禀赋类型，结合全员人口数据库，描述社区人口特征，开展农村社区禀赋类型和人口特征关系研究；通过走访调查和问卷调查，掌握社区和农户发展状况，凝练社区和农户典型实践模式、操作主体模式；结合案例，寻找社区和农户发展模式的关键影响因子；以空间换时间，总结农村社区和农户发展演化规律；基于区域功能定位和内生优势，探寻区域发展主导模式。用社区微型调查法研究人口行为，用跨尺度的视角审视衰落农村发展问题，将提高人口地理学家跨尺度的综合研究能力，将丰富和完善衰落农村可持续的人口发展理论。

In recent years, Demographic behavior research has attracted much attention. The study has made significant progress in population distribution, population control, urban integration, rural construction, household behavior, household livelihood and other fields. Because of lacking the micro investigation of community, there is few cross-scale experience, understanding and perception of life logic hiding in demographic behavior for geographers. The theory innovation on demographic geography is restricted. In this project, Shrinking Village natural endowment types are divided by the multi-dimensional geographic features and community demographics are described by the full population database - A case study of Nihewan basin. The community and household typical practice modes and the practicing mainstay modes are identified by means of questionnaire and field surveys, which is useful for understanding the development of communities and households. The key impact factors of various community and household development mode are retrieved by comparing these cases. The evolution law of development of community and household is summarized by place as a substitute for time; Based on function orientation of regional development, and endogenous advantage, the regional leading mode of shrinking village is explored. The demographic behavior is studied by micro survey method, and the shrinking village development is studied from the perspective of cross scale, which will improve the comprehensive research ability of the demographics geographers, and will enrich the theory of sustainable population development in the shrinking village.
