| 总结: | The impact of land use changes on the riverine environment ofthe
Liwagu-Labuk River Basin has been studied. Intensification of several
land use activities such as agricultural, tourism, industrial and
settlements have led to competition for water and land resources among
the stated sectors. Deterioration of the river water quality has been
affirmed through declining water quality index (WOI) or river class
category and increased suspended sediment loading. For most of the
monitoring stations} water quality parameters are within the DOE
specified range for Class II river though occasionally deteriorated to
Class III for those located at the downstream. The suspended sediment
loading in the river has increased significantly, from 215.4 mg/L (in
1971-1980) to 434.6 mg/L (in 1993-2000), which is approximately twice
of the earlier record. Literature search, interview, ground survey, river
classification and comparison between previous and current land uses
have been employed for this study_ Briefly, it is apparent that the
effects of unplanned development activities would be the degradation of
the environment} as for this study is the declining river water quality
caused by total suspended solids (TSS). |
