英文摘要 | Previous studies on saline-alkali soil management mostly followed an instrumental "prediction and control" approach dominated by technical end-of-pipe solutions. However, those "integrated" instrumental solutions frequently perished due to the growing social & economic uncertainties in financial support, legal insurance, expertise service and other factors. This investigation summarizes the 30-year period of saline-alkali soil management - the social and economic and ecological (SEE) management innovation - its adoption, diffusion, adaptation and transformation in Manasi River watershed of northern Xinjiang. This area was experiencing three distinct SEE management stages from pure instrumental desalination techniques to integrated desalination technique system following the SEE supporting system. The results of GIS analysis (Fragatats 3.3) and historical documents provide data evidence for above three transition stages. The total area of saline and alkali land was increased by 32.7%, 47.6% during the first two decades but decreased by 11.9% in the recent decade. The numbers of saline land patches were 116, 129 and 121 in 1989, 2000 and 2007 respectively, a similar trend to the changes of total area. However, both perimeter-area fractal dimension (PAFD) and splitting index (SI) continued to increase, with values of 1.265, 1.272 and 1.279 for PAFD and 259.29, 269.68, 272.92 for SI in 1989, 2000 and 2007, respectively. It suggests that saline and alkaline land distribution had been fragmented, and sequestrated into salt micro-catchments within whole oasis ecosystems. This case is largely associated with effective adoption of integrated engineering and biological desalination programs as a result of local SEE saline-alkali soil management innovation. |
