| 内容記述 | This study aimed to elucidate the relationship between the water quality of irrigation ponds and land use ratio of the catchment of ponds in Tsukuba City located in the suburban region of Tokyo. The land use for the catchment was shown as the paddy ratio, the dry field ratio, the housing ratio and the forest ratio. The numerical values of a correlation matrix were used to examine the relationship between water quality and land use of the irrigation pond catchments. During fine weather, positive correlations were significant at a 1% probability for the density of inorganic nitrogen (Inorg-N) in the dry field ratio and the housing ratio. The correlation was significantly negative at a 1% probability for the density of Inorg-N in the forest ratio. However, the correlation between the dry field ratio and Inorg-N was not significant the day before rainfall. Therefore, the land use ratio as related to Inorg-N was examined by multiple linear regression analysis. Results revealed the dry field ratio was the most important factor during fine weather and the housing ratio the most important during rainy weather. | |||||||||||
