摘　　要：为评价洱海湿地昆虫生态发展现状,运用复杂网络理论,以昆虫种群为网络节点,相关性为边,构建了昆虫生态网络的拓扑结构模型。通过模型特征参数分析,得出昆虫生态网络符合小世界和无标度网络特征,节点度分布服从幂律分布。运用拓扑结构破坏方法仿真了网络生态的动态演化过程,研究发现网络中重要物种和濒危物种消失对网络稳定性将造成指数级影响,结果表明:昆虫生态网络演变具有自然普适规律,维持网络稳定性是昆虫生态保护的关键策略。In order to evaluate the current state of insect ecological development in Erhai wetland, complex network theory is used to construct a topological structure model of insect ecological network with insect populations as network nodes and correlations as edges. By analyzing the characteristic parameters of the model, it is concluded that the insect ecological network conforms to the characteristics of small world and scale-free network, and the node degree distribution obeys the power law distribution. The method of destroying the topology is used to simulate the dynamic evolution of the network ecology. The study shows that the disappearance of important species and endangered species have an exponential impact on the stability of the network. The evolution of insect ecological network adapts to the natural universal law, and the maintaining network stability is the key strategy in the insect ecological protection.
