    摘要:

    河流的健康状况与人类社会的兴衰息息相关。通过河流自然性评价,才能掌握河流的健康状况。以汤河为例,在划分河段的基础上,运用层次分析法(AHP),利用由22个定量、定性指标组成的河流自然性评价体系,从地貌、生态、水文特征3个方面对汤河进行了自然性评价。将评价结果分为4个等级:自然型、近自然型、退化型和人工型,其综合评价结果与聚类分析检验结果基本一致。研究数据表明,汤河总体上处于近自然状态,但个别区段已退化十分严重。该文建立的河流自然性评价体系可作为京郊河流评价的参考,其评价结果可作为汤河未来生态建设的依据。

    Abstract:

    River health has great influences on the rise and decline of human society.The assessment of river naturalness can easily tell us whether a river is healthy or not.By taking Tanghe River as an example,the river naturalness was assessed from geographic,ecological and hydrological aspects by using analytical hierarchy process(AHP).The naturalness assessment is made based on the division of the river channel by establishing a river naturalness assessment system composed of 22 qualitative and quantitative indicators.By the final assessment result,the naturalness can be classified as four grades: natural state,near-natural state,degraded state,and artificial state,which coincide with the result from clustering analysis.Analysis of the data indicates that Tanghe River is in the near-natural state on the whole,but some portions of the watershed have been seriously degraded.The naturalness assessment system established in the study may serve as a reference for the assessment of rivers in Beijing suburb and the result from the assessment may provide a basis for future ecological construction of Tanghe River.
