摘要
选取了湘西猕猴桃的6个生态指标及富硒的特色生长指标共7项统计指标,并在地域方面随机抽选20个县市样本.分别用最长距离法、类平均法、重心法、最短距离法四种常见的系统聚类方法对样本进行聚类分析.通过SPSS软件进行统计分析,将20个样本县市分为六类.最后对比分析四种聚类结果,详细探讨了湘西猕猴桃异地推广种植的可行性,并结合当地经济社会情况为20个县市样本是否引入种植猕猴桃提供了有效的建议.
This paper selects seven statistical indexes of Xiangxi kiwifruit to investigate,they are six necessary ecological indexes and a special selenium-rich index.Twenty counties and cities are randomly selected as samples to consider,and these samples are analyzed by four common systematic cluster analysis methods,which are namely the longest distance,the shortest distance,the average distance and the gravity distance methods.By using of SPSS,the twenty samples are classified into six groups through statistical analysis.Finally,the feasibility of planting Xiangxi kiwifruit in other regions is discussed in detail after the comparison of the four cluster analysis results,and several effective suggestions are also be offered,which concerns on whether kiwifruits should be introduced into a specific region according to local economic and social conditions.
