通过对余姚城区11个公园绿地74种林木的的调查,按叶片受损、枝桠受损、植株受损分类,在2013年7-8月高温期间,大量林木受到高温危害。大树移植和一些不合理的种植方式加剧高温危害。人工浇水和恰当的模式搭配可适当缓解高温危害。适地适树和高温期间开展选择性养护是缓解高温危害的有效途径。
Through the investigation of 74 species of trees in 11 parks and green parks in Yuyao urban area, a large number of trees were endangered by high temperature during the high temperature period from July to August in 2013 according to the damaged leaves, the damaged branches and the damaged plants. Big tree transplantation and some unreasonable planting methods exacerbate the danger of high temperature. Artificial watering and the appropriate model can be properly mitigated with high temperature hazards. Appropriate conservation trees and high temperature during the selective conservation is an effective way to alleviate the high temperature hazards.
