牧草地流转价格空间分异格局及形成机制分析——以内蒙古西乌珠穆沁旗为例

以内蒙古西乌珠穆沁旗（西乌旗）为例,分析牧草地流转价格的空间结构及其形成机制。首先运用克里金插值法研究其空间分异特征,然后利用相关分析和空间计量模型揭示牧草地流转价格空间格局的形成机制。结果显示：西乌旗牧草地流转价格由旗北部、东南部向外围逐渐递减,并呈现出东高西低的趋势;牧草地流转价格空间自相关特征显著且呈空间集聚格局,但也存在由于少量空间异质性而呈现的局部离散格局;流转价格受草地用途、草地产草量、是否签订合同的影响最显著,牧户年牧业纯收入和个人承包面积对牧草地流转价格影响次之。研究结果为宏观把控该地区牧草地流转价格的总体情况,以及完善不同区域草地流转市场提供了参考信息。

Spatial Differentiation Pattern and Formation Mechanism Analysis of Transfer Prices of Grazed Grassland--Taking West Ujimqin Banner of Inner Mongolia as an Example

The objective of this study were to characterize the spatial distribution pattern of transfer prices of grazed grassland in West Ujimqin Banner of Inner Mongolia,and to reveal its corresponding formation mechanism.The Kriging interpolation method was used to assess the spatial differentiation pattern of transfer prices of grazed grassland in this region,and then correlation analysis and spatial measurement model were employed to reveal its formation mechanism.The results showed that the transfer prices of grazed grassland in West Ujimqin Banner gradually decreases from the northern and southeastern areas to the periphery,and presented a trend of high in the eastern area and low in the western area.Significant spatial autocorrelation characteristics and an obvious spatial agglomeration pattern of the transfer prices of grazed grassland was observed,but there was also a pattern of local dispersion due to a small amount of spatial heterogeneity.The use purpose and grass yield of the transferred grazed grassland as well as signing contract or not during the transferring process had the most significant impacts on the transfer prices,followed by the annual net animal husbandry income of herdsmen and contracted grazed grassland area of herdsmen.Our results provide a reference information for macro-controlling the overall situation of transfer prices of grazed grassland in West Ujimqin Banner and improving the grassland transfer market in different regions.
