摘　　要：为探讨气象及生态气象质量与湿地生态系统内鸟类变化的关系,文章以香港米埔湿地为例,利用米铺湿地1979—2009年留鸟人工观测数据、香港天文台公布气象数据和以2000—2009年4期等时间间距研究区的景观变化数据,分析湿地内留鸟数量对研究区气象及生态气象质量变化的响应。结果表明:(1)湿地留鸟数量与温度和最低能见度时数相关性显著,与降水量和月均日照时数变化相关性较小;(2)5种生态气象评价指数(EMI)与同期鸟类数量的相关性分析表明,留鸟与综合生态评价指数(ECAI)呈正相关。其中与水体指数(WDI)正相关系数最大,与土地利用退化指数(LDI)负相关系数最大,相关系数分别为0.88和-0.85;而与湿润指数(HI)和植被指数(VDI)相关性较小。研究表明,保护生态环境,调节气候变化幅度,对保护留鸟的生存空间,延续生物的生态平衡具有重要意义。This study investigates responses of resident birds to meteorological conditions and ecological quality in Mai Po Wetland using in situ observations of resident birds,meteorological data from HongKong Observatory,and four landscape change patterns from 2000 through 2009.The results show that：（1） the resident birds number in Mai Po Wetland has significant relations with tem-perature and minimum visibility time,while having no significant relations with precipitation and monthly average sunshine time;（2）the resident birds number has positive correlation with integrated Ecological Comprehensive Assessment Index（ECAI）,among which the resident bird number has a significant positive（0.88） and negative（-0.85） relationship with Water Density Index（WDI） and Land Degeneration Index（LDI）,respectively,but having smaller correlation with Vegetation Coverage Index（VDI） and Humid-ity Index（HI）..This study indicates it is important to protect the ecological environment and to adjust the fluctuation amplitude of meteorological conditions for conserving the living space of resident birds and for maintaining the ecological balance.
