澳门松山公园树木健康评估

Evaluation of Tree Health in Songshan Park, Macao

摘要:

通过调查样带中树木病虫危害和藤本植物危害等指标，对澳门松山公园树木健康状况进行了评估。结果表明，本次调查的6个样带中，2/3的样带处于生长较差状态；所调查的900株树木中，不健康树木涉及20科23属32种，占所调查树木的18.9%。这说明整个松山公园的树木生长较差。提出维护树木健康的建议：(1)尽快研究找出树木病虫害发病机制，切断病害传播途径，彻底消除病虫害；(2)加紧对入侵植物和土著危害藤本的防治；(3)加强景观改造和植被恢复的力度，构建健康的森林群落结构；(4)建立松山公园树木健康预警机制，对树木健康动态进行长期监控。

The results showed that two thirds of the transects and about 18.9% trees were under unhealthy status. The 32 unhealthy species belong to 20 families, 23 genus. It indicated that the trees in this Park were in relatively lower healthy status. Some suggestions were given, including find out pathogenesis of tree pests, cut off the diffusion route; control invasive plants and native harmful plants; reconstruct landscape and restore vegetation to build the healthy community; establish the warning mechanism for long-term monitor of tree health dynamics.
