基于TOPSIS法的直干大叶相思种子园优良家系评价

The Assessment Of Superior Family in Seed Orchard of Acacia auriculiformis Based on TOPSIS Method

利用topsis法对直干大叶相思种子园28个家系进行综合评价,将参试家系分为不同类群,结果表明:5、6、7、9、10、21、25号6个家系为胸径、冠幅较大,树高、枝下高较小的第I类理想家系;1、2、13、14、17、20、22号7个家系为胸径、冠幅中上,树高、枝下高中下的第II类家系;3、15、18、19、23、24、28号7个家系为胸径、冠幅最大,树高最大、枝下高较大的第III类家系;4、8、11、12、16、26、27号7个家系为胸径、冠幅、树高最小,枝下高最大的第IV类家系。由综合评价可知,I、II类家系是种子园重点保留高产家系,III、IV类家系可考虑适时疏伐。

Application Topsis, to dry leaf, into a large seed and family evaluation, can greatly enhance the scientific, efficiency and accuracy. Through analysis for topsis and the facts contrast, 25 family is the best family, 16 family is the bed family. In addition, due to DBH and crown width more better than others, height and height under branch more smaller than others, No.5, No.6, No.7, No.9, No. 10, No21 and No25 as the first ideal superior family. Following ranking, the second ideal family is No. 1, No2, No. 13, No.14, No17, No.20, No.22, the third ideal family is No.3, No.15, No. 18, No. 19, No.23, No.24, No.28, the fourth ideal family is No.4, No.8, No. 11, No. 12, No. 16, No.26, No.27.
