摘要
当蝗灾发生时,需要迅速有效地控制灾情,防止灾情扩大,并要找出最经济的治理策略。同时,标本兼治的治理方法一直是农业部门多年关注的重点。考虑到蝗灾的不同种类特点及现有治理蝗灾各种方法的不同侧重点,综合当地的具体情况,运用层次分析法给出衡量各个治理方法的权重指标和对比运算公式,最后根据最近的灾情情况进行验证,并对结果加以分析。
When having a plague of locust, a rapid and effective method is needed to control the condition and to find out the most economical controlling strategy.
