摘　　要：为促进村庄更好选址布局与建设,该文运用GIS技术、分形几何学、空间句法等方法,研究了鲁甸县龙头山镇村庄空间形态结构与地震及次生地质灾害影响因子的关联性。结果表明:①村庄所处岩层越硬越厚、地势越平坦、距公路越近、距最近居民点越远的区域,村庄建设受限越小村庄形态越复杂。②村庄所处距震中越近、岩层越软越薄、地势越陡峭崎岖、受邻村居民影响越大的区域,村庄紧凑度越高。③村庄建筑长轴方向平行于地震断裂带的数量相对较多,人们利用建筑刚度较大的长轴方向来应对地震产生的较大能量,从而减轻建筑受损程度。④村庄距最近一次地震震中越近、岩层越软越薄、地势越陡峭崎岖、距公路越近,其地质灾害隐患点越多,村庄道路越曲折越复杂。To promote better village location,layout and construction,and by using GIS technology,fractal ge⁃ometry,space syntax and other methods,the correlation between the spatial morphology and structure of villages in Longtoushan Town in Ludian County and secondary geological disasters is studied.The results show that:①The villag⁃es with harder and thicker rock strata,flatter terrain,closer to roads,and further away from the nearest settlements have less restricted village construction and more complex form of villages.②The villages closer to the epicenter,with softer and thinner rock strata,steeper and more rugged terrain,and more influence from neighboring villages have higher village compactness.③The number of village buildings with their long axes parallel to the earthquake fault zone is relatively large.People use the long axis direction with greater structural rigidity to cope with the greater energy gener⁃ated by the earthquake,thereby reducing the damage to the buildings.④The villages closer to the epicenter of the most recent earthquake,with softer and thinner rock strata,steeper and more rugged terrain,and closer to roads,have more potential geological disaster points and more tortuous and complex village roads.
