摘要
在探讨河口生态系统特征和健康内涵的基础上,从生态系统健康的完整性出发寻求河口生态系统健康评价的适宜指标。根据河口生态系统健康评价指标体系构建原则,在充分考虑黄河河口区生态特征的基础上,基于"压力-状态-响应(pressure-state-response,PSR)"模型,从黄河河口区的生物生态、环境质量、社会经济、管理措施和人类健康等方面筛选出50个评价指标,并对每个指标的获取方式和计算方法进行了详细说明,构建了黄河河口区生态系统健康评价指标体系。该指标体系是一个由目标层、子系统、准则层、指标层构成的4层递阶层次指标体系结构。
Based on the discussion over the characteristic and health connotation of estuary ecosystem, the appropriate indices for estuary ecosystem health evaluation from the view of ecosystem integrity were created. With comprehensive consideration of the actual status of the Yellow River estuary ecosystem, on the basis of the PSR (pressure-state-response) model, 50 indices were selected from the evaluation indices including biological ecology, environmental quality, social economy, management measures and human health of the study area, according to the principle of building estuary ecosystem health evaluation indicator system. In addition, the acquisition ways and calculation methods were detailed explained for these indices, then an index system appropriate for the evaluation of Yellow River estuary ecosystem health was established. This system is a four-layer hierarchy-structured index system involving the target layer, the subsystem layer, criterion layer and the evaluation index layer.
