| 摘 要： | 利用压力-状态-响应 (PSR)模型,根据湿地生态系统的特点,建立了包含压力、状态、响应3大类共11个指标的生态系统健康评价指标体系.以遥感数据及统计监测数据为基础,对大沽河口湿地区进行单因子和综合评价,分析了其所处状态、面临的压力及对压力的响应.研究结果表明:(1)大沽河口湿地生态系统健康综合评价指数(CEI)为0.4994,生态系统健康相对较差,人类干扰指数和水文调解指数是影响该河口湿地生态系统健康的最主要因素.(2)研究区湿地呈现出一种斑块破碎的景观,其生态系统结构组织的合理性以及抵抗外界干扰的能力均呈下降趋势.研究结果对于大沽河口湿地的管理、规划和保护具有参考意义,为制定湿地生态系统保护和恢复的对策提供依据.

| Abstract: | A set of assessment indicator system of the wetland ecosystem was established based on the characters of the wetland ecosystem,the theories and approaches of the ecosystem and the pressure-state-response(PSR) model.The main assessing factors are consists of the press,state and response,which were classified into three types with eleven assessing factors.The data used are including the remote sensor and statistic data.The estuary area was an assessment cell.Based on the indicator system established and data,... |
