森林鼠害工程治理区区划方法的研究

Study on forest rodent control area division method

森林鼠害治理工程是一项系统的生物工程,它是对森林害鼠种群管理的最根本措施。无论是采取以经济允许水平为出发点的IPM策略,还是采取以控制种群到最低、甚至消灭为出发点的TPM策略和APM策略,都离不开见效快、成本低的实用控制技术。这就要求我们有确切的针对性,搞好治理区的区划是解决当前问题的重点。根据坡度级、林分类型、树种、郁闭度、林龄、林木前期被害率、前期鼠害频率(间隔年)、春季夹日捕获率、秋季夹日捕获率等与森林害鼠生境相关的因子进行剖析,总结出治理区区划的依据,以利于整个工程的顺利实施。

The treatment engineering of forest rat is a system of biological engineering, It is the most fundamental measure of forest rodent population management. Whether to take the economic injury level as the starting point of the IPM strategy, Or take to control the population to a minimum, even eliminates as the starting point TPM strategy and the APM strategy, All cannot do without practical quick, low cost control technology. This requests us to have accurately pointed, does well the government area the regionalization is the solution current problem key point, in the article according to the slope level, the Judeich type, the tree seed, the shade density, the age of forest, the forest preliminary percentage of injury, the preliminary rat damage frequency （gap year）, the spring clamps Japan the capture ratio, the autumn clamps Japan the capture ratio and so on to harm the mouse habitat correlation with the forest the factor to carry on the analysis, summarizes the government area regionalization basis, favors the entire project the smooth implementation.
