摘要
对湖库的富营养化评价方法选择的科学性直接影响评价的质量。本文通过建立TPLP模型(T-营养状态指数法,P-主成分分析法,LP-多维偏好线性规划模型)来对营养状态指数法进行修正和优化,结合实例给出TPLP模型的应用原则与步骤,给出该方法的优缺点。TPLP模型在对多组湖库同时进行富营养化评价时,评价结果客观性与科学性更强,更有利于相关部门对富营养化的湖库进行治理。
Different evaluation methods for eutrophication of lake or reservoir will affect on final results,which may be correct or deviation. TPLP model was employed to optimize the tropical status index to improve the weigh of each index,make the weigh of each index more scientific and feasible than emprical value of 26 reservoir statistics. Principle and process were given by practical applicaiton,advantages and disadvantages were discussed,and the TPLP model is more objective and scientific than other models especially for the lakes or reservoirs evaluation,and useful for management of eutrophication of lakes or reservoirs.
