【摘要】 对广东省惠州市4个区县已建成的绿化景观林带进行调查,分别选取5种生境的19种景观树种,进行7次周期性样方调查、记录和分析。通过Duncan多重比较分析得出,凤凰木、黄槐、红花羊蹄甲、美丽异木棉等景观树种的胸径生长状况因生境类型的不同而表现出显著差异,树种的成活率受到气候、病虫害和立地条件等多方面影响。结合调查数据统计分析和树种的生物学特性,推荐5种生境条件下的景观林树种配置模式。更多还原

【Abstract】 Nineteen tree species were investigated,recorded and analyzed seven periodic times in five habitat plots of green landscape belt in 4 districts in Huizhou City,Guangdong Province. According to the analysis by the Duncan multiple comparison analysis,the growth condition of diameter at breast height of landscape tree species showed significant differences by different habitat types of Delonix regia,Cassia surattensis Bauhinia blakeana and Chorisia speciosa. The survival rate is also affected by the climate,plant diseases and insect pests,and site conditions,etc. Combined with the survey data statistical analysis and biological characteristics of species,5kinds of habitat landscape forest tree species under the condition of configuration mode are recommend.更多还原
