| 摘 要： | 通过机械取样和典型抽样相结合的调查方法对浙中城市森林主要群落进行了分析及优化研究。以浙中淳安、富阳、诸暨、余姚、舟山等5个城市为研究区，对城市森林树种应用状况及群落类型作了系统调研和梳理，在群落评价选优的基础上，分地区分类型获得了城市森林树种的重要值排序结果。结果表明:①本次调查共获得植物250种，分属于85科170属；种类不算多，但科属类型丰富，说明浙中城市森林绿化对物种的利用还不够。②4类型城市森林中植物种类数排序为城周背景林 > 城市公园片林 > 水岸林 > 道路林，5个城市植物种类数排序为淳安 > 舟山 > 余姚 > 富阳 > 诸暨。③从全域来看，城周背景林与城市人工林组成树种有明显差别；城周背景林各地差异较大，与各地气候、地形等立地条件耦合较好；人工林的地方差异相对较小，同质化倾向较明显。④对比城市森林树种重要值和频数排序直方图，发现重要值对于衡量树种应用状况及其在群落中的地位更为全面，但频数研究简单易行，可作为粗略分析手段。⑤根据重要值指标计算结果，归纳群落量化组合模式并提炼出4种群落类型。图1表4参33

| Abstract: | Through the research of the important values of the tree species in the community, we can fully excavate the relationship information among the tree species, so as to optimize the structure of urban forests. The main community of urban forests in central Zhejiang was analyzed and then optimized by means of mechanical sampling and representative sampling. Each sample size is 10 m×10 m. On this basis, application status of tree species and community types in these urban forests were systematically determined. Based on evaluation and selection of communities, results of urban forest tree species were sorted by importance values and divided by types and areas. Results showed that there were 250 species of plants belonging to 170 genera and 85 families. The number of genera and families were abundant, but species were not. The rank order of four urban forest types based on the number of plant species was urban background forest > urban park > waterfront forest > roadside forest with the five cities ranked Zhoushan > Yuyao > Fuyang > Zhuji > Chun'an. Considering tree species composition for all areas, great differences were found between urban background forests and urban plantations(urban park, waterfront forest and roadside forest). Urban background forests could be divided by regional differences and fit well with climatic and topographical conditions in the distributed region. Urban plantations had small differences among regions. Comparing the importance values of urban forest tree species and using a frequency ranking histogram and importance values to measure the status of tree species and their status in the community was found to be more comprehensive. Results indicated a limited utilization of urban forest greening species in central Zhejiang, but by using importance values and a quantitative combination mode, four community types for central Zhejiang were identified.Ch, 1 fig. 4 tab. 33 ref.] |
