1. Myung-woo Lee, Jong-young Park, Mu- sup Beon Landscape Planning, Fish Biology, Landscape Ecology, Jeonbuk National University Post evaluation on the stream corridor Restoration, Jeonjucheon stream South Korea 2007. 6. 8.

2. I.Introduction + This is about monitoring and post evaluation on the stream restoration works for establishing guidelines of restoration planning and design + The site is the jeonjucheon jeollabukdo, which is well known as the samplary stream restoration works. + We analized the last 4 year ecological changes about fisheries, stream plants and human activity structures in the stream corridor

3. Figure1. study site, Jeonjucheon length 10 km

4. II. Existing corridor features 1. Upstream features: It has high naturality. There are various activities – water front recreation by the elder and residents around the stream

5. 2. Midstream features: It has low naturality. There are parking lots and traditinal market from which pollution emitted. It ’ s connected to urban forest, Daga park. This site might have the potentials for restoration habitat.

6. 3. Downstream features: It has high naturality. There are various activities – water front recreation by the elder and residents around the stream

7. 1.Data collection –Source: ME monthly quality data yr 1999~2005 –Pollution item: BOD, COD, SS, TN, TP –Simulation method: ME, 2004, technical guidelines for total water pollution managenet in watershed III. Water quality evaluation 2. Quality Simulation

8. 3. Water quality evaluation to established criteria upstream, HanbyeokruMidstream, seosingyo 1999200619992006 DO ( ㎎ /L) 1a1a+1a1a+ BOD ( ㎎ /L) 1b1a41b SS ( ㎎ /L) 1111 총대장균군수 ( 수 /100 ㎖ ) 33+63 TN ( ㎎ /L) 66+6 TP ( ㎎ /L) 3266+ 기준시점과 평가시점이 동일한 수질등급으로 평가된 경우 연평균값과 등급별 비율을 바탕으로 상대적으로 수질오염도가 낮은 값에 “+” 를 이용한 평가를 추가함

9. IV. Fish species and its environment 1. Number of fish species every surveying station (2002-2005)

10. 2. evaluation of fish habitat + fish species diversity + fish channel and small dam + stream form, stream bed,

11. 3. evaluation of river plants + existing vegtetation status + designed plants list + guidelines for maintenance

12. V. Human using recreation structure evaluation 1.Surveying method: observation and counting number of user ㆍ date: Sep. 22,Sep. 23, Nov. 4, Nov.26 2006. Number of surveying: 348 persons ㆍ time: AM 6-8, AM 12-PM 2, PM 4-6 ㆍ surveying station: pavilion at Hanbeokbo, basket ball playground at Jeonjugyo, gate ball playground at Dagagyo, etc. Fig. Design layout at upper area in stream corridors

13. 2. questionare analysis: 70 persons ▶ use the site once a day: 68.6%, ▶ use any season: 82.7%, use any day: 80%, walking access: 87.7%, ▶ use during 1-2 hours: 64.3%, use lonely: 44.3%, exercising purpose- 86.4%, ▶ use frequency of sports and resting structures: 2-4 times: 35.7%, ▶ much usefulness of human using structure: 58.6% No use of human using structure: 27.1% ▶ total preference degree: moderate: 42.9%, satisfactory:34.3%

14. 3. counting the user numbers - counting a quarter time ( the most counts happened during AM 6:15- 6:30: 37persons - mainly walking activity

15. 4. Human using structure evaluation + types of structure: path, stepping stone, access road, sports facilities, resting facilities, etc + evaluation A, B, C to the results from surveying 구 분 항 목 상류 중류 하류 한벽정자 전주교 농구장 다가교 농 구장 다가교 게 이트볼장 쌍다리 배후습지 백제교 야외무대 친 수 공 간 친 수 공 간 길 보행로 / 자전거도로 B B A C B B 징검다리 A B A B B B 접근로 B C B C A C 면적인 인공시설물 운동시설 A A A C C B 휴게시설 A A A A B A 생태학습공간 B C B B A C 천변로 및 가로수 천변로 및 가로수 C C A C C C
