摘　　要：随着城市化步伐的加快以及大量水利工程的建设,在人为因素的影响下河流生态系统呈现退化趋势。通过遥感解译、调研采样及文献资料收集等方式,建立了太子河流域生态系统退化综合评价体系,并针对评价结果对太子河进行了生态退化的时空分布讨论。从退化标准上看,太子河生态系统退化DI为0.609分,尚处于轻度退化状态,生态系统比较合理,格局尚完善,受人类干扰较少,自身恢复能力较强,功能较为完善;目前存在趋于中度退化的趋势,其中地貌生境特征和水文水资源特征退化较明显,得分为53.5及40.67。该指标体系可为其他地区河流的生态退化评价研究工作提供一定的借鉴,可以有力支撑河湖管理部门制定相关决策。With the acceleration of urbanization and the construction of a large number of water conservancy projects,the river ecosystem presents a degradation trend under the influence of human factors.Through remote sensing interpretation,investigation and sampling and literature collection,a comprehensive evaluation system of ecosystem degradation in Taizi River Basin is established.The temporal and spatial distribution of ecological degradation in Taizi River is discussed according to the evaluation results.In terms of degradation standard,the degradation Di of Taizi river ecosystem is 0.609,which is still in the state of slight degradation.The ecosystem is relatively reasonable,the pattern is still perfect,less disturbed by human beings,strong self restoration ability and perfect function.At present,there is a trend of moderate degradation,in which the degradation of geomorphic habitat characteristics and hydrological and water resources characteristics is more obvious,with scores of 53.5 and 40.67 respectively.The index system can provide some reference for the ecological degradation evaluation of rivers in other areas,and can effectively support the river and lake management departments to make relevant decisions.
