景观格局对流域水文影响研究指标的分析

Analysis of the Studied Indicators for the Influence of Landscape Pattern on the Hydrology of River Basin

通过对景观格局与水文关系研究过程中所选择的指标进行分析,建议研究中水文指标选择径流系数、年径流深变差系数、洪水特征参数,水质指标选择TN、TP、SS、CODMn,景观指数选择斑块面积、景观破碎度、聚集度等。

Through the analysis of the selected indicators in the process of the studies on the relationship between landscape pattern and hydrology,it is suggested that,in the research,hydrological indicators select runoff coefficient,annual runoff variation coefficient,flood feature parameter,that water quality indicators select total nitrogen,total phosphorus,suspended solids,and chemical oxygen demand [Mn],and that landscape indicators choose vegetation patch area,landscape fragmentation degree,agglomeration degree and so on.
