Study on the Factors and Effects of Stress of Ecosystem Health in Chongqing Metropolis

重庆市是中国最大的内陆山区城市,人类活动强烈,生态系统脆弱;又位于长江三峡水库的库尾,生态地位十分重要,开展重庆都市圈生态系统健康研究具有特殊的意义。在详细阐述都市圈生态系统健康受胁迫现状的基础上,从地质地貌结构、河谷型气候、土壤性状、植被与生物多样性、人类活动等方面分析了都市圈生态系统健康受胁迫因子及影响机理、影响途径,并探讨了生态系统健康受损对都市圈环境、气候变化、人体健康等的胁迫效应及趋势,为制定都市圈生态系统健康规划与管理提供参考依据。

Chongqing is one of the largest inland mountainous cities, where the activities of human beings are intense and the ecosystem is fragile. It lies in tail area of Three-Gorges reservoir, the important ecological status makes it necessary to investigate the ecosystem health of Chongqing metropolis. On the basis of demonstrating the stressed situation, the factors of stress, its influencing mechanism and influencing approach of ecosystem health in Chongqing metropolis are analysed from geomorphological structure, river valley climate, soil properties, vegetation and biodiversity, human activities. In addition, the effects of stress and its trend of metropolitan environment, climate changes, human health are discussed due to ecosystem health^s being damaged, in order to put forward to references for setting out the programming and management.
