【摘要】：借助TOPSIS模型、空间探索性数据分析和地理加权回归模型等方法,系统分析河北省县域农业机械化水平的空间特征、关联水平及其影响因素,以期为因地制宜地推进农业机械化发展提供支撑。结果表明:1)2013年河北省县域农业机械化水平在空间上呈现明显的方向性和地形分布差异:中南部偏东平原地区的农业机械化水平较高,北部偏西地区次之,西部丘陵区发展滞后;2)县域农业机械化发展水平存在较强的空间自相关特性,区域趋同性比较明显,河北南部以高高集聚(HH)类型居多,北部以低低集聚(LL)类型居多;3)与OLS模型相比,GWR模型在揭示农业机械化水平空间非平稳性方面具有优势。在研究所选的自变量中,地形因子对县域农业机械化的影响较大且均为正向,耕地经营规模和种植结构对农业机械化水平的影响有正有负,但整体上为正。建议在高原县域采取适度增加耕地经营规模,调整作物种植比例等措施提升农业机械化发展水平,在平原县域通过改变其他经济因素来提高发展水平。
[Abstract]:With the help of TOPSIS model, spatial exploratory data analysis and geographical weighted regression model, this paper systematically analyzes the spatial characteristics, correlation level and influencing factors of county agricultural mechanization level in Hebei Province. With a view to local conditions to promote the development of agricultural mechanization to provide support. The results showed that: 1) in 2013, the level of agricultural mechanization in county area of Hebei Province showed obvious spatial directionality and topographic distribution difference: the level of agricultural mechanization was higher in the south-central east plain region, followed by the north and west region. The development of agricultural mechanization in the western region lags behind. 2) the development level of agricultural mechanization in the county area has strong spatial autocorrelation characteristics, the regional convergence is obvious, and the high concentration of (HH) is the main type in the south of Hebei Province. Compared with the OLS model, the GWR model has advantages in revealing the non-stationary spatial characteristics of agricultural mechanization. Among the independent variables selected in the study, topographic factors have great and positive effects on agricultural mechanization at county level. The effects of cultivated land management scale and planting structure on the level of agricultural mechanization are positive and negative, but on the whole are positive. It is suggested that appropriate measures should be taken to improve the development level of agricultural mechanization in plateau counties, such as increasing the scale of cultivated land management and adjusting the proportion of crop planting, and improving the level of development in plain counties by changing other economic factors.
