摘要
为了研究河西走廊地区农民土地价值观的空间依赖性与异质性,在大样本实证调查资料的支持下,通过李克特量表的模糊综合评判,采用基于Geoda软件平台的探索性空间数据分析方法(ESDA),探讨了河西走廊地区农民土地价值观的空间相关性。结果显示:1)河西走廊地区农民土地价值观总体上具负的空间自相关性,表现为空间不均衡性,但不剧烈。2)农民土地价值观局域空间差异显著,呈极化或逆极化状态。H-L区和L-H区占空间单元的一半以上。3)农民土地价值观维度特征不均衡,土地情感价值、财富价值、权利价值总体上具负的空间自相关性;保障价值总体上具正的空间自相关性;权利价值县域间差异较大,保障价值差异性较小,达到空间相对均衡状态。农民土地价值观的空间差异格局是群体差异的空间表现形式,通过农民土地价值观对土地利用行为的导向作用,为寻求土地利用新空间提供一个全新的视角。
In order to study the spatial dependence and heterogeneity of the land values of farmers in Hexi Corridor region of Gansu Province, this paper discussed the spatial correlation of the land values of farmers by using the fuzzy comprehensive evaluation of Likert scale and the exploratory spatial data analysis(ESDA) based on the Geoda software platform and large empirical survey sample data. The results showed that: 1) Land values of farmers showed a negative spatial autocorrelation with spatial imbalance, but were not intense in Hexi Corridor region of Gansu Province. 2) Land values of farmers had significant local spatial differences, which presented a polarization or reverse polarization state.H-L and L-H areas took more than half of the space units. 3) Dimension feature of land values of farmers was imbalanced. The land emotional value, wealth value and property rights value had negative spatial autocorrelations as a whole. Land security value had a positive spatial correlation as a whole. The differences among the counties were rather big in right value and were small in security value, which led to a spatial relative equilibrium state. The variability in spatial pattern of land values of farmers was the spatial expression form of group differences. The guiding role in land values of farmers provided a new perspective for seeking a new land use aspect.
