통일신라시대 월지(月池) 입·출수 체계의 원형과 구조

Abstract

This research explored the relationship between the water quality issue of Wolji Pond (Anapji Pond) with themaintenance of the channel flow circulation system. The water supply and drainage system closely related to thecirculation system of pond has been reviewed, rather than the existing water supply and drainage system that hasbeen analyzed in previous studies. As a result of reviewing the water supply system, it has been learned that the water supply system on thesoutheastern shore of Wolji Pond, being the current water supply hole, has been connected to the east side gardenfacility (landscaping stone, curved waterway, storage facility of water) between the north and south fence and thewaterway. This separate facility group seems to have been a subject of the investigation of the eastern side of WoljiPond, with the landscaping stones having been identified in the 1920’s survey drawings. The water supply facility on the southeastern shore, being the suspected water supply hole, seems to have someconnection with the granite waterway remaining on the building site of Imhaejeon (臨海殿) on the southern side ofWolji Pond. It is inferred that it provides clean water, seeing that the slope towards the southwestern shore of WoljiPond becomes lower, the landscaping stones have been placed in the filter area, and it is present in the 1920’s surveydrawings and the water supply hole survey drawing of 1975. The water drainage facility on the northern shore is composed of five stages. The functions of the woodenwaterway and the rectangular stone water catchment facility seem not to be only for the water drainage of WoljiPond. In light of the points that there are wood plugs in the wooden waterway and that there is a water catchmentfacility in the final stage, it is judged that the water of Balcheon Stream (撥川) may be charged in reverse accordingto this setup. Namely, the water could enter and exit in either direction in the water drainage facility on the northernshore It also seems that the supply to the wooden waterway could be opened and shut through the water catchmentfacility of rectangular stone group as well. The water drainage facility on the western shore is very similar to the water drainage facility on the northernshore, so it is difficult to avoid the belief that it existed during the Silla Dynasty, or it has been produced by imitatingthe water drainage facility on the northern shore at some future point in time. It seems to have functioned as the water drainage facility for the supply of agricultural water during the Joseon Dynasty. The water supply and drainage facilities in Wolji Pond have been understood as a systematized distributionnetwork that has been intertwined organically with the facility of Donggung Palace, which was the center of the Sillacapital. Water has been supplied to each facility group, including Wolji Pond, through this structure; it includes thedrainage system connecting to the Namcheon River (南川) through the Balcheon Stream, which was an importantcanal of the capital center.
