green area for environmental protection
Examples
- The df of production greenland is small ; the df of shelter forest is large , indicating that production greenland has simplest perimeter pattern , while shelter forest most complex perimeter pattern . 4
生产性绿地的分维数最小，防护绿地的分维数最大，接近于1 . 5 ，说明生产性绿地的边界格局最简单，防护绿地的边界格局最复杂。 - 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 evaluation of green spaces is the base of green space construction . as an important part of urban green space , the green space of industrial district exerts the ecological , social and economic benefits . however , the research on the synthetic benefit of green space and it configuration pattern is still lack
但目前对绿地综合效益所作的评价和配置模式的研究还比较少见，本研究在普查的基础上，选取了办公区绿地、车间防护绿地、厂区游园和生活区绿地共四种功能区的四种典型配置模式样地为研究对象。
