Abstract: In this paper，Tongyu county，Dehui county and Antu county of Jilin province were taken as typical counties to study the differences of spatial patters of rural settlements. The results were useful to carry out land consolidation，optimize land use pattern and promote intensive use of land in rural areas. Compling Kernel Density Estimation method，Ripley’s K function，landscape metrics with spatial analysis methods of GIS，the study deeply and comprehensively analyzed the differences of spatial patterns of rural settlements among three typical counties and the factors which influence the spatial distribution of rural settlements. The results showed that，the distribution pattern of rural settlements in Antu presented as band pattern，while that of Dehui and Tongyu displayed a dispersing pattern. The L（h）function value indicated that the aggregation level of rural settlements in Antu was the highest among the three typical counties，while that of Dehui was at the lowest level. The radiation function of roads on rural settlements decreased with the distance from the roads，especially in Antu. The influence of river on the spatial distribution of rural settlements in Antu was obvious，but was not significant in Dehui and Tongyu. More than 90% of rural settlements were concentrated on the region with slopes less than 10 degrees in three typical counties. The rural settlements of Antu also spreaded at other slope grade.
