| Abstract: | Proposing and determining p degrees of the early-warning indexes about Harbin water resources sustainable utilization.A feedback therapy is used to determine the p limit of the warning indexes,and warning effectiveness is tested by two-time test.Warning lights system is designed to monitor and warn Harbin water resources sustainable utilization;Warning index is predicted by SVM,and trend warning about Harbin water resources sustainable utilization is tested,including single index trend warning and multi-index trend warning, and the result of the trend warning is got. |
