| 摘 要： | 农户是农业用地的直接支配者,其对农业土地利用的决策直接影响农业景观格局.分析影响农户土地利用决策的因素,可为指导农业用地合理利用提供科学依据.以陕西省米脂县孟岔村为例,在地块尺度上,通过构建相似度框架,定量分析相邻关系、血缘关系和社会经济条件对农户土地利用决策(将地块种植作物视为农户土地利用决策)的影响,阐明微观土地利用变化的驱动机制.结果表明:①相邻关系(居住位置相邻)与农户土地利用决策具有微弱关系,不存在农户决策相似性随距离衰减的情况；②血缘关系中以兄弟关系数量最多,68.92％的兄弟关系中农户决策倾向于相似和偏相似,兄弟关系对农户土地利用决策具有较为显著的影响；③农户社会经济条件与农户土地利用决策关系密切,表现为随社会经济条件相似度的增加,农户决策相似度呈现出先增加后减小特征.以2008年数据对研究结果进行验证,表明了结果的一致性. |

| Abstract: | Farmers living in rural China are the direct users of agricultural land and their decision-making affects the agricultural landscape. Decision-making of farmers is an important aspect of farmer land use behavior at the micro-scale,and provide new pathways to explore at the macro-scale. We selected Mengcha village (Mizhi County,Shaanxi) in northwest China as an example in this study. We conducted several investigations of farmer decision-making and family structure,income,consumption,parcel information including location and planting corps,house location and relationship between farmers from 2007 to 2010. We selected neighborhoods,kinship networks and farmer socioeconomic conditions as key factors,and parcel-level crop planted as the independent factor. For understanding how decision-making of farmers is influenced by neighborhood,kinship and socioeconomic condition,similarity was introduced to calculate neighborhood similarity (NBSLY),kinship similarity (KSSLY),socioeconomic similarity (SESLY),and parcel-level crop planted similarity (PCSLY). On the basis of the similarity values and two-dimensional tables,we analyzed the relationship between PCSLY-NBSLY,PCSLYKSSLY and PCSLY-SESLY and found that the frequency of similarity and partial similarly of decision-making in neighboring farmers was 58.97% ,and 67.12% dissimilarity and partial dissimilarity in the non-neighboring farmers. The similarity proportion of decision-making between farmer houses with the longest distance was bigger than the closet distance. Similarity of farmer decision-making did not diminish with distance between neighboring houses in the small village. For KSSLY,the relationship between father-son and uncle-nephew was less than brotherhood, which led to difficulty in determining the interaction between these relationships and farmer decision-making. However,brotherhood accounted for a considerable proportion in KSSLY, 68.92%. Brotherhood in KSSLY reflected considerable influence on farmer decision-making. Farmer decision-making was correlated with SESLY and as SESLY increased from 0 to 0.75, PCSLY showed an increasing tendency,but decreased when SESLY exceeded 0.75. We used 2008 data and were able to verify our results. |
