摘要: <正>以L-V模型为例,对模型高精度参数的确定方法进行了研究。在考虑观测误差和不考虑观测误差的两种情况下,综合优化规则、运算精度、运算时间,以及仿真机器的性能等各方面因素,设计出高精度参数确定的方法。该方法具有计算速度快、参数精度高等优点,可以推广应用到其他模型中。

Abstract: Eight kinds of ecological prevention techniques had been applied to the sloping of Ninghang expressway. The results indicated that net-suspended spray seeding (NSSS), spray seeding (SS), grass-stick technique (GST), liana protection (LP) and grass protection (GP), were the best preventative ways to prevent soil erosion, to renew succession and to form stable ecological communities, which have broad application.
