The stable infiltration rates in the different DLU were also lower
than those in the OLU, ranging from 0.45 to 2.89 mm/min. The
soil stable infiltration rates in the DLU displayed the following
order: DSA3 (2.89 mm/min) NSGB (2.65 mm/min)NDSA2
(1.89 mm/min)NDSA1(1.64 mm/min)NCR (0.45 mm/min),
which indicated that the runoff regulating capacity of DSA3was
the strongest, while that of CR was the weakest. Among the
various OLU, the soil stable infiltration rates ranged from
2.83 to 6.22 mm/min, with NFL exhibiting the highest rate
(6.22 mm/min). Thisfinding showed that NFL had the most pro-found effect on the water retention function among the original
landforms in the project area. Hence, the destruction of large
areas of forest ecosystems should be avoided during the
construction process, particularly in a National Nature Reserve
in whichnon-essential land disturbance and construction should
be completely avoided
