• The results is showed as following : ( 1 ) within the four typical configuration patterns of the green spaces in front of office buildings , the small arbor + shrub + ground layer pattern has the best ecological benefits , with the evaluation result of 0 . 6847 while shrub pattern has the worst ecological benefits , with the evaluation result of 0 . 5385 ; small arbor + small shrub + ground layer pattern has the best aesthetic benefits with the evaluation result of 0 . 9691 while the tall arbor pattern is the worst , with the result of 0 . 6893 ; shrub pattern has the lowest investment with the highest evaluation result of 1 . 000 while small arbor + small shrub + ground layer pattern has the highest investment of construction and maintenance with the lowest economic evolution result of 0 . 301 ; small arbor + small shrub + ground layer pattern has the best comprehensive benefit with the evaluation result of 0 . 7961 while tall arbor pattern has the worst comprehensive benefits with the result of 0 . 6698
  在配置模式上，以小乔+小灌+地被为佳。乔木层的盖度应控制在40左右，且选择树姿挺拔，树型高大的种类，灌木层盖度以30 40为宜，且姿态优美，观赏性强。 ( 2 )车间防护绿地的四种典型配置模式以大乔+灌木模式的生态效益最好，结果为0 . 8257 ，草坪的生态效益最差，结果为0 . 3265 ；美学效益以小乔+小灌木模式最好，结果为0 . 8448 ，草坪模式最差，结果为0 . 7304 ；经济投入以小乔+小灌最低，评价值最高，达到1 . 000 ，草坪模式最高，评价值最低，仅达到0 . 2310 ；综合效益以大乔+灌木最好，结果为0 . 8111 ，草坪最低，评价结果为0 . 5035 。
• The appliance range of traditional tree - gauge arithmetic is narrow . this paper provide a new method of the choice of the tree . this method is based on the matrix and the finite element equation , so it can be called matrix method . this mathod adopts 1 range number of the matrix as the condition to choose branches of the tree , it is theoretically optimal , the analyses of calculation also shows that this arithmetic is excelled traditional method
  本文提出了一种新的树规范选择算法。这种算法是建立在对系数矩阵与有限元方程进行分析的基础上的，所以被称为矩阵法。由于采用了向量的1范数作为选择树支的条件，所以这种算法在理论上是最优的，实际的算例的分析也表明这种算法优于传统算法。
