In this work the level and structure of consanguinity is analysed in two Spanish rural regions of similar geographic and orographic characteristics for the period between 1880 and 1979, employing two different methodologies. The estimates according dispensations shows that the total levels (alpha4 = 0.00552 in La Cabrera and 0.00405 in Fuentes Carrionas) and the structures of consanguinity (C22/C33 = 0.43 and 0.34) are similar in both regions, but have evolved differently. Whereas in La Cabrera both parameters have remained stable, in Fuentes Carrionas they fluctuated through the period analysed. On studying the structure of consanguinity more closely using the isonymic method, it can be seen that in La Cabrera total consanguinity (Ft = 0.0206) should be attributed mainly to environmental factors (Fr = 0.0193) and to a lesser extent to socio-cultural factors (Fn = 0.0013), whereas in Fuentes Carrionas it derives, almost exclusively, from the former (Ft = 0.01270; Fr = 0.01589; Fn = -0.00325).
在这项研究中，运用两种不同方法，分析了1880年至1979年间西班牙两个地理和地形特征相似的农村地区的近亲结婚程度和结构。根据豁免情况的估计表明，两个地区的总近亲结婚程度（拉卡布雷拉地区α4 = 0.00552，富恩特斯卡里奥纳斯地区α4 = 0.00405）和近亲结婚结构（C22/C33 = 0.43和0.34）相似，但演变情况不同。在拉卡布雷拉地区，两个参数都保持稳定，而在富恩特斯卡里奥纳斯地区，它们在分析期内有所波动。通过姓氏相同法更仔细地研究近亲结婚结构可以看出，在拉卡布雷拉地区，总近亲结婚程度（Ft = 0.0206）主要应归因于环境因素（Fr = 0.0193），在较小程度上归因于社会文化因素（Fn = 0.0013），而在富恩特斯卡里奥纳斯地区，它几乎完全源自前者（Ft = 0.01270；Fr = 0.01589；Fn = -0.00325）。
