| 摘 要： | 在田间试验和网室内系统测定的基础上，对稻萍鱼螺生态系统的群落结构和食物链行为进行了数学模拟．用插值法解析了稻萍群落模型；并在此基础上用差方方程Q_(t 1)=Q_te~-J_t表达了群落中的萍鱼食物链关系．所得的数学模型通过计算机运行后，得出了优化的群落食物链结构并成功地应用于实践．

| Abstract: | Through three years systematic observation on field and wire netting protected experiments,a set of mathematics model about the community status and food chain actions in rice-azolla-fish-mudsnail system was obtained.The rice-azolla community status was expressed in interpolation equations.Adifference equation:which was based on the interpolation equations,was used to express the food chain actions.Through a system simulation derived from the mathematics model,an optimized structure of the rice-azolla-fish-mudsnail ecosystem was odtained and successfully applied in field production. |
