其他摘要The recession and revitalization of old industrial cities concerns urban industrial evolution and its characteristics. Based on the theory of evolutionary resilience, we developed an analytical framework for the industrial structure evolution of old industrial cities, and applied the framework to a case study in Shenyang. The following conclusions are drawn. First, since 1978, Shenyang's industrial growth capacity has shown fluctuation between 'contraction-expansion'. As the secondary industry has a much stronger expansionary and contractionary capacity for growth, this results in lacking stability leading to industrial structure transformation. Second, since 1999, the orientation towards a high-end manufacturing industry in Shenyang has weakened, and the evolution of the new and old growth path is characterized by low-end orientation. Third, since 2007, Shenyang's industrial innovation output capacity has dropped sharply which has been significantly affected by scientific and technological personnel and enterprise-owed science and technology institutions and to a less extent by R&D expenditure. We applied the resilience theory to study the industrial evolution of an old industrial city, explored new study perspectives on industrial evolution and verified the applicability of the resilience theory. This paper provides a scientific reference for understanding the recent deceleration in economic growth in the Northeast old industrial base, and for exploring new paths toward revitalization. Ferrihydrite (Fh) and calcite were used as reactive capping layers for a eutrophic lake. The effectiveness of Fh and/or calcite capping for demobilizing phosphorus (P) in the sediment from the overlying water was tested, and the responses of carbon (C), nitrogen (N), and iron (Fe) to different capping treatments were analyzed as well. Twelve sediment cores were collected randomly using polycarbonate tubes from Ornamental Lake in the Royal Botanic Gardens of Melbourne, Australia. Four groups with three replicates were separated randomly and labeled as the control (no capping), calcite (capped with 1-cm-deep calcite), Fh (capped with 1-cm-deep synthesized Fh powder), and calcite + Fh (CaFh, capped with 0.5-cm-deep Fh powder first and then with 0.5-cm-deep calcite). Gentle bubbling was employed to prevent anoxic conditions in the sediments and stimulate vascular plant ventilation during a 15-day static incubation. The overlying water sample mixed by a small magnetic stirrer was withdrawn 1, 3, 7, 11, and 15 days after capping for the analyses of filterable reactive phosphorus (FRP), filterable N, and Fe species. The results showed that CaFh had a greater effect on the FRP removal in the overlying water than Fh alone. No significant Fe release was observed for Fh and CaFh compared to the control and calcite. The introduction of Fh increased the release of ammonium and total N. After incubation, no significant differences were observed among total P, total N, and organic carbon in the upper sediments, except for total Fe.
