摘要
基于天津、辽宁、河北因美国白蛾入侵而造成的非经济损失案例研究,评估2004年美国白蛾造成的全国非经济损失总量,合计为140.35亿元,平均为11.99万元/hm2,并利用CLIMEX软件进行分析推算,得到了美国白蛾在我国的可能生存区为29省(市、区)346县(市),潜在的非经济损失将达到139 280亿元。
On the basis of cases studies on non - economic loss evaluation in Tianjin, Liaoning and Hebei, the paper further estimates that the national total loss for Hyphantria cunea (Drury) in the year of 2004 is RMB 14035 million, and the average is RMB 119 956.87 per hm^2. At the same time, it points out that the potential non- economic loss caused by Hyphantria cunea is RMB 13 928 000 million, covering 29 provinces/cities and 346 counties, according to Lin Wei (1991) by means of CLIMEX statistic software.
