【摘要】：[目的]以新疆各地區(qū)為基本單元,對其農(nóng)業(yè)機械化發(fā)展水平進行區(qū)劃,為分類指導(dǎo)全疆各地區(qū)農(nóng)機化發(fā)展提供依據(jù)。[方法]以2001~2014年統(tǒng)計數(shù)據(jù)作為數(shù)據(jù)源建立了農(nóng)機化發(fā)展水平指標體系,并提出了指標標準值。構(gòu)建了基于指標標準值、熵和變異系數(shù)的指標組合賦權(quán)法。依據(jù)此法,為各指標賦予權(quán)重,從而建立新疆2001~2014年14地區(qū)農(nóng)機化發(fā)展水平關(guān)系數(shù)據(jù)模型。以各地州2001、2005、2010及2014年的農(nóng)機化發(fā)展水平作為聚類樣本,應(yīng)用系統(tǒng)聚類法對其進行區(qū)劃分析。[結(jié)果]從時間維度上,4個年段新疆各地州農(nóng)業(yè)機械化發(fā)展水平在簇間距離閥3.5、4.4、4.8和5.2條件下區(qū)劃時,各劃分區(qū)域農(nóng)機化發(fā)展水平呈現(xiàn)出先高低分化,后趨同的態(tài)勢。從空間維度上昌吉、巴州、塔城、博州和克拉瑪依等5個地州農(nóng)機化發(fā)展水平在不同的區(qū)劃距離閥和時段內(nèi)均顯現(xiàn)為高度相似特征。[結(jié)論]以北疆為主的劃分區(qū)域中相鄰地區(qū)農(nóng)機化發(fā)展水平聚集效應(yīng)較明顯。同時區(qū)劃結(jié)果也揭示,烏魯木齊、哈密、吐魯番和喀什在4個區(qū)劃年段中農(nóng)機化發(fā)展水平的高度相似特征。其余各地區(qū)在研究年段內(nèi)農(nóng)機化發(fā)展水平聚集效應(yīng)較弱。為不同地區(qū)農(nóng)機化發(fā)展水平區(qū)劃、農(nóng)機化管理和服務(wù)政策的制定提供了參考。
[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.
