초록
In recent years, the drying of the water spider habitat has been progressing rapidly. This is the primary cause of extreme climatic events in 2014/2015 with overall reduction in annual precipitation, but impermeable clayey layer formed in the superficial formation also plays an important role. The clayey layer is a critical factor in the formation of wetlands on a well-drained lava plateau, but paradoxically, it restricts the connection with ground water, increasing the instability of the water balance and making it precipitation-dependent structure. In addition, construction of roads/drainways has also caused drying of wetlands by blocking or rapidly spilling surface water/sheet flow. Therefore, to keep the wetlands sustainable, it should increase the flow into the wetlands by removing the road/drainways and floodgates installed to reduce the outflow.
Abstract
In recent years, the drying of the water spider habitat has been progressing rapidly. This is the primary cause of extreme climatic events in 2014/2015 with overall reduction in annual precipitation, but impermeable clayey layer formed in the superficial formation also plays an important role. The clayey layer is a critical factor in the formation of wetlands on a well-drained lava plateau, but paradoxically, it restricts the connection with ground water, increasing the instability of the water balance and making it precipitation-dependent structure. In addition, construction of roads/drainways has also caused drying of wetlands by blocking or rapidly spilling surface water/sheet flow. Therefore, to keep the wetlands sustainable, it should increase the flow into the wetlands by removing the road/drainways and floodgates installed to reduce the outflow.
