Character Exploration for River Ecology Condition Based on Factor Analysis

Abstract:

The basis of analysis of the ecological health of the river is taken into account, including water quantity, water quality, riparian zone, the physical structure of organisms and other elements to explore a new method based on factor analysis of river ecosystem health. 21 typical reaches along villages of Tang River in Beijing are measured using the method of 17 indexes system to analyze the index relevance for Tang River ecosystem health. The results showed that midstream of Tang River ecological health relevant factors are riverbed, water and biological effects, water quality, water-soil interaction, the downstream river bank only have slope factor, and significantly related reaches are distributed in water and biological effects, heart beach shape, river curvature, slope degree more. The evaluation results raised the indexes and reach affecting river ecological condition, to provide scientific guidance for the ecological restoration of Tang River (Beijing Reach).
