Correlation Between Water Quality and Land Use Change in Ciliwung Watershed

摘要

Due to the change of land use, Ciliwung watershed suffered from physical degradation. Considering the increasing land use change along the Ciliwung watershed, it was necessary to perform a research on land use change and its impact on the river water quality (BOD, COD, DO). The land-use forms were divided into six categories: waterbody, bareland, forest, built-up area, agriculture and paddy field. The level of correlation was measured by Pearson correlation. The change of land use of waterbody, bareland, forest, built-up area and dry land agriculture influenced the river water quality. Waterbody had positive effect on water quality, while bareland and built-up area had a negative effect on water quality.
