一种狩猎者为有限食饵而具自竞争的生态方程及其应用

AN ECOSYSTEM EQUATION OF THE HUNTER SELF-COMPETITION BY LIMIT TO FOOD AND ITS APPLICATION

赤眼蜂和螟虫之间的生态系统是一种典型的狩猎者为有限食饵而具有自竞争的生态系统。根据这种系统的生物学特点,构造出一个生态模式,并对其作了定性分析和计算机数值模拟。结果表明,本文模式较之Volterra-Lolka生态模式,在描述天敌治虫规律上,更为切合实践并具有一定的理论意义。

The applied example of ecosystem of between trichogramma and moth's larva,to be a typical ecosystem of hunter self-competition by timit to food. Based on biological characteritics of the ecosystem,to made up bioecological model, and toke it to make qualitative analysis and numerical simulated test on computer.The test results were indications that the model of this text, it described the law of natural enemy eliminate insect pest, was conform to reality, more than the bioecological model of Voterra-Lotka and have some theoretical significance.
