发布时间：2019-06-10 07:09
【摘要】：[目的]以新疆各地区为基本单元,对其农业机械化发展水平进行区划,为分类指导全疆各地区农机化发展提供依据。[方法]以2001~2014年统计数据作为数据源建立了农机化发展水平指标体系,并提出了指标标准值。构建了基于指标标准值、熵和变异系数的指标组合赋权法。依据此法,为各指标赋予权重,从而建立新疆2001~2014年14地区农机化发展水平关系数据模型。以各地州2001、2005、2010及2014年的农机化发展水平作为聚类样本,应用系统聚类法对其进行区划分析。[结果]从时间维度上,4个年段新疆各地州农业机械化发展水平在簇间距离阀3.5、4.4、4.8和5.2条件下区划时,各划分区域农机化发展水平呈现出先高低分化,后趋同的态势。从空间维度上昌吉、巴州、塔城、博州和克拉玛依等5个地州农机化发展水平在不同的区划距离阀和时段内均显现为高度相似特征。[结论]以北疆为主的划分区域中相邻地区农机化发展水平聚集效应较明显。同时区划结果也揭示,乌鲁木齐、哈密、吐鲁番和喀什在4个区划年段中农机化发展水平的高度相似特征。其余各地区在研究年段内农机化发展水平聚集效应较弱。为不同地区农机化发展水平区划、农机化管理和服务政策的制定提供了参考。
[Abstract]:[objective] to divide the development level of agricultural mechanization in Xinjiang as the basic unit, and to provide the basis for the classification and guidance of the development of agricultural mechanization in all regions of Xinjiang. [methods] the index system of agricultural mechanization development level was established by using the statistical data of 2001 / 2014 as the data source, and the standard value of the index was put forward. An index combination weighting method based on index standard value, entropy and coefficient of variation is constructed. According to this method, each index is given weight, and the data model of agricultural mechanization development level in 14 areas of Xinjiang from 2001 to 2014 is established. Taking the development level of agricultural mechanization in 2001, 2005, 2010 and 2014 as clustering samples, the regionalization analysis was carried out by using system clustering method. [results] in terms of time dimension, when the development level of agricultural mechanization in various states of Xinjiang was divided under the condition of 3.5, 4.4, 4.8 and 5.2, the development level of agricultural mechanization in each divided region showed the first and high differentiation. The trend of convergence after. From the spatial dimension, the development levels of agricultural mechanization in Changji, Bazhou, Tacheng, Bozhou and Karamay are highly similar in different regionalization distance valves and periods. [conclusion] the accumulation effect of agricultural mechanization development level is obvious in the adjacent areas of northern Xinjiang. At the same time, the results of regionalization also reveal the highly similar characteristics of the development level of agricultural mechanization in Urumqi, Hami, Turpan and Kashgar. The accumulation effect of agricultural mechanization development level was weak in other areas during the study period. It provides a reference for the regionalization of agricultural mechanization development level, agricultural mechanization management and service policy in different areas.
