Abstract
The above ground biomass and annual net productivity of Salix nipponica were estimated by the allometric method in the littoral zone of Parksil-nup wetland, Hapcheon-gun, Gyeongsangnam-do Korea. The density of stems and individuals per hectare were 14,950 and 6,140, respectively and the mean number of stems per individual was 2.43. The proportion of the above ground biomass of stem, branch, and leaf were 59.2%, 28.3% and 12.5%, respectively. The standing crops was 109.7 ton/ha and total phytomass was 926.7 ton in the study area. Annual net production was 25.3 ton/ha estimated from the standing crops and the age structure.
경상남도 합천군 박실늪에서 선버들 자연림의 지상부 현존량과 연순생산력을 상대생장법으로 조사하였다. 선버들의 ha당 개체 밀도는 6,140본이고, 분지된 줄기는 14,950개로서 한 개체당 분지된 줄기는 평균 2.43개였다. 지상부 각 부위별 현존량의 비율은 줄기 59.2%, 가지 28.3%, 잎 12.5%였다. 각 부위의 건중량과
