采用5株优势木对比法，以胸径、树高、材积为生长指标，同时结合枝下高、通直度、尖削度、枝叶浓密度和侧枝粗等形质指标，在广东省汕头潮阳西环山、潮州饶平石壁山和仙春村、惠州西湖公园宝塔山等9个地点开展了台湾相思的优树调查研究。总共筛选了43株候选优树和215株优势木进行统计分析，并归纳总结出了广东省台湾相思优树选择的技术标准，即优树树高＞5株优势木平均树高，胸径≥5株优势木平均胸径的1.17倍,单株材积≥5株优势木平均单株材积的1.52倍，形质指标0.33A（尖削度得分）+0.32B（通直度得分）+0.35C（浓密度得分）＞2，最终入选的台湾相思优树有19株，入选率为44.2%。
採用5株優勢木對比法，以胸徑、樹高、材積為生長指標，同時結閤枝下高、通直度、尖削度、枝葉濃密度和側枝粗等形質指標，在廣東省汕頭潮暘西環山、潮州饒平石壁山和仙春村、惠州西湖公園寶塔山等9箇地點開展瞭檯灣相思的優樹調查研究。總共篩選瞭43株候選優樹和215株優勢木進行統計分析，併歸納總結齣瞭廣東省檯灣相思優樹選擇的技術標準，即優樹樹高＞5株優勢木平均樹高，胸徑≥5株優勢木平均胸徑的1.17倍,單株材積≥5株優勢木平均單株材積的1.52倍，形質指標0.33A（尖削度得分）+0.32B（通直度得分）+0.35C（濃密度得分）＞2，最終入選的檯灣相思優樹有19株，入選率為44.2%。

Based on quantity indexes (DBH, tree height and individual volume), in combination with quality indexes (under-branch height, stem straightness, tapering grade, canopy density and branch size), the selection criterion of Acacia confusa superior trees was established by using method of ifve-dominant-trees contrast. The investigations on A. confusa plus trees selection were carried out by using the designed superior tree selection criteria in nine test sites of Guangdong province, such as Shantou Xihuan Mountain, Chaozhou Gubi Mountain and Xianchun Village, Huizhou Xihu Park Baota Mountain and so on. The 43 candidate trees and 215 contrast trees were ifltered out for statistical analysis. According to the results, a set of technical standards of A. confusa superior trees selection for Guangdong province were summarized as follows:the selected excellent tree’s tree height should be greater than that of 5 average dominant tree, the selected excellent tree’s DBH should be greater than or equal to 5 1.17 times of the average DBH of 5 average dominant tree, the selected excellent tree’s single tree timber volume should be greater than or equal to 1.52 times of that of 5 average dominant tree per tree, and the tree form quality index 0.33A (tapering grade score)+0.32B (stem straightness score)+0.35C (canopy density score) should be greater than 2. Lastly, nineteen superior trees in 43 candidate trees were selected according this criterion and the selected ratio was 44.2%.
