摘要
[目的]探讨基于元胞自动机模型模拟洱海水体演化的可行性.[方法]以洱海水体为例,根据入湖河流的径流量和入湖口的地理位置,进行聚类分析,构建入湖河流模型;基于元胞自动机模型构建洱海水体的演化模型,模拟对洱海水体TN、TP的净化能力.[结果]春末到秋初,对洱海水体TN、TP的净化能力较强;秋末到春初,对洱海水体TN、TP的净化能力较弱;对洱海水体TN、TP的全年净化总量分别为1 158.76、287.73 t,净化效率分别为79.94％和93.63％.[结论]元胞自动机模型对洱海水体TN、TP的净化效果良好,且对洱海自身的水质改善、水资源保护和利用具有积极作用.
Abstract
[Objective] To research the purifying capacity of Erhai water body to TN and TP,and to discuss the feasibility of simulating Erhai water body evolution based on cellular automata model.[Method] Erhai water body was used as the research material.According to the runoff volume of inflowing rivers and the geographical position of lake inlet,cluster analysis was carried out,so as to establish the model of inflowing rivers.Evolution model of Erhai water body was established based on cellular automata model.Purifying capacity of Erhai water body to TN and TP was researched.[Result] From late spring to early autumn,Erhai water body had relatively strong purifying capacity to TN and TP.From late autumn and early spring,Erhai water body had relatively weak purifying capacity to TN and TP.The total purifying quantities of Erhai water body to TN and TP were 1158.76 and 287.73 t,respectively.Their purification efficiencies were 79.94％ and 93.63％,respectively.[Conclusion] The model has relatively good overall purifying capacity of Erhai water body to TN and TP,and has positive action to the water quality improvement and water resource protection of Erhai.
