摘要/Abstract

摘要： 于2017年期间，每日间隔1 h自动监测1次，同步测定广州南沙湿地与珠海淇澳红树林林内、林外旷地的气温及大气相对湿度，比较研究不同地点红树林生境的生态效应。结果表明，两地红树林林内气温一直低于林外旷地，相对湿度则高于旷地。南沙红树林日降温最大值6.832 ℃，平均降温0.733 ℃，平均降温率3.092%；日增湿最大值23.416%，平均增湿5.528%，平均增湿率6.345%。淇澳红树林日降温最大值6.607 ℃，平均降温1.722 ℃，平均降温率7.011%；日增湿度最大值45.044%，平均增湿1.681%，平均增湿率1.942%。两地红树林林内气温年均值比较，南沙比淇澳高0.126 ℃，林外旷地气温年均值淇澳比南沙高0.862 ℃；红树林林内湿度年均值南沙比淇澳高4.427%，林外旷地湿度年均值南沙比淇澳高0.581%。总体上，两地红树林的降温、增湿效应均明显，其中淇澳红树林降温效应更明显，而南沙红树林增湿效应更明显。

Abstract: In 2017, the temperature and air relative humidity of open spaces within and around mangrove at Nansha wetland, Guangzhou, and Qi’ao Island, Zhuhai, Guangdong Province were automatic investigated simultaneously every hour for everyday to estimate the ecological effects of mangrove at different habitats. During the whole year, the temperature within the mangrove both at Nansha and Qi’ao were lower than that around it, but the humidity was higher. Within the mangrove at Nansha, the daily maximum decreased temperature was 6.832 ℃ with the mean value of 0.733 ℃ in the average percentage of 3.092%, while the daily maximum increasing humidity was 23.416% with the mean value of 5.528% in the average percentage of 6.345%. Within the mangrove at Qi’ao, the daily maximum decreased temperature was 6.607 ℃ with the mean value of 1.722 ℃ in the average percentage of 7.011%, while the daily maximum increasing humidity was 45.044% with the mean value of 1.681% in the average percentage of 1.942%. For annual mean air temperature within mangrove, there was 0.126 ℃ higher at Nansha than that at Qi’ao, but for open spaces there was 0.862 ℃ higher at Qi’ao than that at Nansha. For annual mean humidity within mangrove, there was 4.427% higher at Nansha than that at Qi’ao, and for open spaces there was 0.581% higher at Nansha than that at Qi’ao. In total, the effects of decreased air temperature and increasing humidity were relative obvious, and much apparent at Qi’ao for decreasing temperature, while much apparent at Nansha for increasing humidity.
