基于共词分析的甘肃省种植业热点领域分析

Hot area of planting field in Gansu Province based on co-word analysis

从研究学科领域发展的特点出发,根据文献计量学原理,采用共词矩阵挖掘工具分析系统——书目共现分析系统(BICOMB),对2006～2011年甘肃省种植业领域科技论文的高频关键词进行共现处理,并利用SPSS软件和平均距离法进行关键词聚类.结果表明:2006～2011年期间甘肃省种植业领域的科技论文产出整体呈上升态势;研究的热点主要包括新品种选育、引进和试验推广,灌溉方式及施肥对春小麦水分利用效率、产量的影响,栽培模式、播种方式对作物产量、品质的影响,以及瓜果蔬菜的病虫害防治和无公害栽培等8个方面,其中以马铃薯、小麦、玉米、番茄、苹果、葡萄、辣椒的栽培技术、种植模式、病害防治的报道最多,栽培技术中以地膜覆盖、套种和温室无害化栽培的研究为主.

Starting from the characteristics of research disciphnes development, accorclmg to me princi- ple of literature metrology, and use the analysis system of co-word matrix mining tools -Bibliographic Item Co-Occurrence Matrix Builder （BICOMB）, and the high frequency keywords of planting scientific papers during 2006-2011 in Gansu province co-occurrence processing, and key words clustering by SPSS software and the average distance method, and the results show that the number of planting scientific papers during 2006-2011, as a whole on the rise; the hot topics research mainly includes new varieties breeding, introduc- tion and promotion test, the influence on spring wheat water use efficiency and yield under irrigation and fertilization, effect of cultivation mode and sowing methods on crop yield and quality, and pest control and pollution-free cultivation of fruits and vegetables etc. eight aspects, the most of the reported is about pest control, planted model and pollution-free cultivation on potatoes, wheat, corn, tomato, apple, grape, the main research of cultivation technique are about film mulching, the interplanting and greenhouse harmless cultiration.
