摘要：指出了目前各省市都在风景园林工程中投入了大量的人力物力,随着科技的发展,对于城市生态风景园林建设的要求也逐步提高。植物配置是园林设计中的重要组成部分,直接影响到生态风景园林的综合效益,而植物的生态效益在植物配置中又起着决定性作用。从园林植物的生态功能、园林植物的配置原则和植物配置的生态效益的研究进展等角度进行了探讨,提出了相应的建议,以期为相关研究提供参考。

摘要：This paper studies the growth law of 23-year-old Castanopsis fissa planta- tion in Haiming forest farm （Pingguo County, Baise City, Guangxi Province） with the method of stem analysis. The results show that the average DBH, tree height and volume of the 23-year-old C. fissa plantation are 19.4 cm, 20.4 m and 0.326 1 m3 respectively. The fast growing periods of DBH, tree height and volume are the 2^nd- 8^th, 6^th-11^th, 6^th-23^nd year. Annual increment curve and average increment curve of volume haven＇t intersected in the 23 years, which means the 23-year-old C. fissais plantation has not reached the quantitative mature age. The growth equations of DBH, tree height and volume are D=1.713 3T-0.050 6T2＋0.000 7T2-1.942 2, H= 1.925 7T-0.039 8T2-2.489 0, V=-0.010 4T-0.002 4T2-4.084 8e^-0.005 T2＋0.012 7. Ac- cording to the volume regression equation of Castanopsis fissa, it will reach quanti- tative maturity in the 24~ year.
