近十几年来,在害虫种群的研究方面,不论从生态学特性,还是研究方法均有显著进展,尤其对种群与环境的关系认识不断深入,并引进了“系统”的概念。在计算数学方面,电子计算机日益广泛应用。在数学方面,许多数学分支学科相继渗入害虫测报这个领域。因此,害虫测报工作近年来进展很快。不仅提高了单项对象预测的质量,而且正向着最优化的预测和控制、综合管理方面前进。 今将自己看到的部分文献,综合介绍如下: 一、害虫测报的概况 害虫测报是数学生态学的一个分支学科,它用数学的理论和方法来表达与分析生物的生态过程或系统的行为动态的定量关系。因此,要作好害虫的测报工作,必须既 In recent ten years, there has been notable progress in pest population research both in terms of ecological characteristics and research methods. In particular, the understanding of the relationship between population and environment has been deepened and the concept of “system” has been introduced. In computational mathematics, electronic computers are increasingly used. In mathematics, many branches of mathematics one after another into the pest forecasting in this area. Therefore, pest forecasting work has progressed rapidly in recent years. Not only does it improve the quality of single-object predictions, but it is also moving forward with optimal forecasting and control and integrated management. Now some of the documents I have seen are summarized as follows: I. General Situation of Pest Forecasting Pest forecasting is a branch of mathematical ecology that uses mathematical theory and method to express and analyze the biological process or behavior of the system The quantitative relationship. Therefore, we must make the measurement of pests, we must both
