中国城市森林生物灾害的发生现状及控制展望

城市林业对城市生态系统的平衡具有重要的作用,都市环境的非自然化及其环境胁迫的日趋严重,导致城市林木灾害的成因复杂,严重威胁城市景观和人居环境的安全.同时,城市作为物流的主要集散地,有害生物入侵的风险非常高.本文从城市林业的特点、功能出发,依据生态学原理阐述了生物灾害在城市环境植物中的发生特点、原因及其影响.从城市森林生物灾害的防治现状出发,指出防治中存在的问题,提出了合理预防、监测、治理的对策,并对城市森林健康的管理及研究方向作了展望,以促进城市林业的健康发展,从而使城市生态系统稳定发挥其重要的作用.

Occurrence and Control of Urban Forest Biological Disaster in China

Urban forestry plays an important role in maintaining the balance of urban ecosystem. With the heavier urban environmental and natural environmental stress, the causes of urban forest pests became more complicated, which threatened the urban landscape and habitat security. As logistics sites, cities are of higher risk of harmful biological invasion. From the viewpoints of the characters and functions of urban forestry, the authors explained the occurrence, causes and implications of biological disasters in urban plant environment based on ecological principles. According to the present situation of urban biological disaster prevention and control, the problems existed were pointed out and the countermeasures in preventing, monitoring and controlling these disasters were suggested. The management and research on urban forest health were prospected so as to promoting the sound development of urban forestry and making full play of the urban ecosystem.
