摘　　要：白蚁是热带亚热带生态系统非常重要的分解者,而且对环境变化敏感。全球气候变暖直接影响到生物多样性的变化,已成为世界最为关注的环境问题。为了阐述气象温度变化对白蚁群落的影响,本文利用主成分分析和典型相关分析,对澳门南亚热带城市森林生境约1年的白蚁发生情况与气象温度因素之间的关系进行了分析。研究结果显示,澳门白蚁群落与气象因素之间多不具有相关性,但其中白蚁物种丰富度和培菌性白蚁功能群丰富度与气象温度因素之间存在典型相关性;澳门南亚热带城市森林系统中,培菌性白蚁功能群的丰度与月均气温、月均最高气温、月均最低气温、月均地下10 cm土壤温度和月均最低表层水温负相关。本研究认为培菌性白蚁丰度对于南亚热带城市森林的气象温度具有作为指示生物的潜力。Global warming has become a challenge that can affect the patterns of biodiversity. Termites are particularly important decomposers in tropical and subtropical forest ecosystems. Many studies have indicated that termites are sensitive and can respond to environmental changes,but the study of how termite assemblages respond to changes in the meteorological temperature factors in urban forest ecosystems is lacking. A survey of termite assemblages was conducted in the urban forest remnants in Macao city. Based on Canonical correlation and Pearson correlation analyses,there were no significant correlations between termite data and whole meteorological temperature data in Macao,but the encounters of both termite species and fungus-growing group were closely related to whole meteorological temperatures. This year-round study showed that the number of encounters of termite assemblages, especially the fungus-feeding group,may be more suitable used to indicate meteorological temperature changes. The fungus-feeding group encounters negatively correlated with air temperature (℃),maximum temperature (℃),minimum temperature (℃),soil temperature at 10 cm depth (℃),and minimum surface water temperature (℃) in lower subtropical urban forests in Macao. The study suggested that termite encounters are susceptible to meteorological temperatures in the lower subtropical urban forest ecosystem.
