This project since May 17, 2013 execution to May 16, 2014, completed on schedule before the end of the period, the following brief description of the current implementation of the outcome:
This project has been completed Kaoping coastal pollution investigations, gravel pits and dredging works in Li- gang Bridge and the bridge between upstream in Li-ling Bridge, the cable-stayed bridge downstream of the weir downstream Kaoping and Tan Ping Road embankment outside the four rivers bare beach location for major pollution sources Kaoping coast, while Kaoping dry season due to flood obvious during the flood water, rain washes Kaoping low coastal beaches that showed substantial at low water beach naked, in the strong winds will cause rivers dust events.
Air quality information from the calendar year 2005 to the end of March 2014 due to poor air quality events caused rivers dust events occurred a total of 15 stations in total. Overall, the concentration of suspended particles Kaoping coast has been presented since 1966 to improve year by year, the high concentration of suspended particles predilection month still concentrated in 10 to 12 months and the next year between 1 to 3 months per year
Statistics from May 2013 to April 2014 in 150 days of inspections, which were found in four days time river dust events, dated 2013, 7/1, 7/2, 8/6, and 2014 2/6, the dust event major river of dust outside the park Tam Lin Ping Road embankments, trees District weir at the management center and 0.5km downstream weir upstream to the river-stayed bridge, the main impact area for the Dashu Dist, Daliao Dist, sub-to the affected area as Linya Dist,Meinong Dist and Qishan Dist
That comparing with 2013 dust event so special for the river, the year Linya Dist is located outside the Tanping Road in bare ground under similar meteorological conditions observed on site exposed to the dust of their area, dust volume and scope are significantly reduced, PM10 concentrations from another level of dust events, outside the dike north of bare ground measured Daliao stations are also significantly reduced from the current bare-ground station data and determine the cause of this phenomenon the main reason for the current year the lake level road embankment outside the bare ground vegetation grew well, lush vegetation, when a dust event occurs, this river vegetation can effectively suppress dust raised bare ground, and the other along the bare ground Seventh River Management Office applied for the construction method also effectively inhibited exposed to dust raised
In addition to horizontal linkages year Pingtung County Environmental Protection Bureau and river management units Kaoping dust control of consultative meetings, the other two sessions Kaoping river has been handled dust pre-notification drills operations, strengthening the dust after the river incident, Pingtung II county liaison mechanism will help future regulatory effectiveness of river dust.
