| Abstract: | A fixed site observation of Picea crassifolia forest communityin Sidalong forest zone in Qilian Mountain(north slope)was conducted.The contents of nutrient elements in overstorey,understorey(ground veget-ation), litter and soil were measured respectively.The contents and varia-tion laws of 9 elements in different organs of the trees were also analy-zed and illustrated respectively,These results will greatly contribute to abetter understanding of the forest ecosystem structure and function, and theforest management. |
