摘要本论文通过对公园绿地和附属绿地抽样调查和对道路绿地全面普查的方法, 对铜山新区的树种应用情况作出研究。通过调查分析可知,铜山新区共有有园林 绿化树种 178 种,分属于 59 科,111 属。常绿树(包括竹类)与落叶树之比为 1:1.62;乔木、灌木与藤本之间的比例为 7:6:1。在乔木中,常绿与落叶的比例 是 1:3.09,常绿灌木与落叶灌木的比例为 1:0.87。通过整理数据得出,铜山新 区共有乡土树种 84 种,外来树种 94 种,两者的比例为 1:1.12。经过实际调查 可知,外来树种的使用数量远大于乡土树种。应该增加铜山新区的落叶乔木和乡 土树种的使用量,适当引入外来树种,达到生态园林城市的建设要求。69093
