本研究旨在评估沙巴亚庇市中心主要树木的健康状况。本研究采用树木目测法或视觉树木评价法（VTA）制定了主要的评价标准。本研究旨在通过观察树木的根、茎、枝和叶来确定损伤或缺陷对树木的影响。研究区域有五个区域，即从KK Lama和Mackelton Point（1区）到Pasar Besar。树木健康参数从病虫害的存在、树木健康、树叶颜色、树木的生长速度、树木的感染和树根的潜在失效进行评估。本研究共观察到白蚁、真菌、蚜虫、蘑菇、真菌、寄生虫、蚂蚁、杂草和粉虱等9种树木病原和病虫害。结果表明，在研究区688株乔木中，共有23种。研究发现，该州平均树叶颜色正常，生长速度适中，树木的感染仍在控制之中。树根的潜在失效也处于较低水平。总括而言，树木的整体健康状况处于良好和中等水平。本研究旨在为香港大会堂管理层进行树木健康检测提供参考，同时也为大学生进行树木健康评估提供参考。
This study aimed to assess the health of main tree in the Kota Kinabalu City Centre, Sabah. In this study, principal evaluation standards were made by using visual observation of trees or Visual Tree Assessment (VTA). This study was conducted to identify any effect of damage or defect on trees via the observation of trees at their roots, stems, branches and leaves. There were five zones in the study area, namely from KK Lama and Jesselton Point (Zone 1) to Pasar Besar. The tree health parameters were evaluated from the presence of pests and diseases, trees health, foliage colour, the growth rate of trees, infections of the trees and potential failure of tree roots. In this study, nine of pathogens, pests and diseases of trees were observed, which were termites, fungi, aphid, mushrooms, epiphytes, parasites, ants, weeds and Whiteflies. This study showed that there were 23 species from the 688 stand of trees in the study area. The study found that the state average foliage colour was normal, a moderate growth rate and infection of the tree was still under controlled. The potential failure of tree root was found in low level as well. In a nutshell, the overall health of trees was found to be in good and moderate levels. This study was conducted as a reference in health detection of tree for The City Hall management (DBKK) and also as a reference for University students in conducting tree health assessment.
