摘要： 以太浦河为例，基于PSR模型构建针对水体和河岸带的多指标评价体系，运用熵权法计算指标权重，通过PSR模型和物元可拓模型对太浦河进行分段分类分级评价.结果表明：上游江苏吴江段分类结果为“高压力-较好状态-低响应能力”类型；中游浙江嘉善段为“低压力-中等状态-低响应能力”类型；下游上海青浦段为“低压力-中等状态-高响应能力”类型.吴江段河流健康状况评估结果为Ⅲ级（差），嘉善段和青浦段均为Ⅱ级（一般），且倾向于Ⅰ级（好），表明虽然河流目前的健康状态一般，但由于制定的政策在一定程度上有效，可通过进一步加大保护水源地力度逐步实现水源地健康状况恢复.研究结果可为太浦河分区治理和河岸带生态化建设提供决策支持.

Abstract: Taking Taipu River as an example, a multi-index assessment system for the water body and riparian zone is constructed based on the PSR model. Index weights are calculated with the entropy weight method, and the Taipu River is evaluated using the PSR and matter-element extension models. The results show that the Wujiang segment is classified as “high pressure-good state-low response ability”, the Jiashan segment is classified as “low pressure-medium state-low response ability”, and Qingpu segment is classified as “low pressure-medium state-high response ability”. The result of the health assessment of Wujiang is Grade Ⅲ (poor). Meanwhile, Jiashan and Qingpu are both Grade Ⅱ (medium), but leaning towards Grade I (good); this indicates that although the current health status of the river is medium, the health status of the water source area could be gradually restored by further increasing protection of the water source given that the policy is to some extent already effective. The results can provide decision support for river management and ecological construction of the riparian zone in Taipu River.
