摘要
以上海嘉定新城绿地为例,采用随机均衡样方法对24种常见园林树种的病虫害进行调查,将绿地分为街旁绿地、居住区绿地、道路绿地3种类别。结果发现,树木受害主要有3个方面原因:受气候变暖影响的病虫危害;土壤结构导致的生理性病害;种植过密导致植株受害,其中受气候变暖影响的病虫对园林树木的危害是最主要的原因。垂柳、合欢、杜鹃和香樟受害最严重。该研究为新建绿地病虫危害原因寻求积极有效的解决途径,以期实现以点带面,为上海其他新建绿地树木种植及养护起到较好的借鉴作用。
The random equilibrium method was adopted for the green space of core area of Jiading.In the field survey of 24 common landscape trees, it was found that there are three main reasons for tree damage:pests and diseases affected by climate warming,physiological diseases caused by soil structure, and planting damage caused by high-density planting, among these climate warming was the most important factor to cause pests and diseases. Salix babylonica, Albizia julibrissin, Rhododendron simsii, Cinnamomum camphora were seriously damaged in this survey and whose comprehensive assessment was the least.The proactived and effective solutions to reduce the pests and diseases in new green land,in order to achieve a better suggestion for the construction and maintenance of other newly-built greenland trees in Shanghai.
