研究村庄格局演变，对于制定新时期农村土地利用政策、建设社会主义新农村有一定指导和借鉴意义。以江苏邳州市的吴楼村为典型实例，采用当面问询式访谈和GPS量测的方法分析黄淮海平原中部地区村庄格局的演变。结果表明：1）该村经历了新中国成立前绝对缓慢发展、改革开放前相对缓慢发展以及20世纪80年代快速扩张、90年代稳定前进、新世纪逐步衰退的系列演化格局，并伴随道路和池塘的相应变化。2）经济原因、社会结构演变、城镇化、村民传统观念变革及不同时期国家政策影响是村庄格局演变的主要因素，而村内人口数量变化是根本。3）改革开放以前村庄规模变化较小，改革开放以来至90年代是村庄规模扩大最明显的时期，2000年左右村庄内部空弃房屋开始增多。4）新中国成立后，人口大量增加、改革开放和市场经济发展、核心家庭地位提升以及保护耕地意识淡薄等是村庄规模大面积扩张的主要原因。5）近期村庄空废房屋大量出现主要缘于城镇化和市场经济影响、户籍管理制度不断放松、种粮比较效益低及计划生育政策实施等。

英文摘要：

The study on the village pattern evolution is important and significative to consti tute the policy of land utilization in the new period and to build new socialist countryside. The Huang-Huai-Hai Plain, located in the central part of East China, is the important farm belt, and consists of multitudinous villages with a high population density. In this re- gion, the marketization level and urbanization level are high because of close to the coastal developed areas, and the interior development problems of the villages are prominent such as a mass of farmlands being occupied, and too many houses being abandoned. So it is one of the representative regions to research problems of village development. Progress in the study related with countrysides, settlements, farmers, and villages have been reviewed. Studies of the village pattern evolution on macroscopic scale were much more than those on microscopic scale, so microscopic studies should be strengthened to better understand village development. The Wulou village in the central part of the Huang-Huai-Hai Plain was chosen as a typical case. The face-to-face interview and the global position system （GPS） measurement method were used in the study. The main re- suits are as follows： Firstly, the Wulou village went through a series of evolution pattern including the ab- solute tardiness development before the establishment of People＇s Republic of China in 1949, the relative tardiness development before the implementation of the economic re- forms in 1978, the fast expansion in the 1980s, the steady scale in the 1990s and the reces- sionary development in the early 21st century. In the meantime, the roads and ponds in the village have also been changed correspondingly. Secondly, the main factors of the vil- lage pattern evolution included economic improvement, the change of social structure, ur- banization and the effect of national policy. However, population variation was still the decisive factor. Thirdly, the change of village scale was n
