摘 要：
通过对陕北靖边县海子梁村荒漠化草原长爪沙鼠的危害状况调查研究,结果表明:平均相对鼠密度645.93有效洞口/hm2,平均经济损失228.69元/hm2,鼠密度与牧草减产量及其经济损失量之间呈正相关关系,R=0.938,有效洞口数(X)与草地植物减产量(M)的线性回归方程为:M=0.836 X-32.10。用溴敌隆进行大面积防治,测得在防治成本42.75元/hm2、防效为73.34%时,防治收益为167.72元/hm2,投入产出比1∶3.92;经济允许损失率8.00%,约为实际损失率(31.42%)的1/4;经济损害水平193.46有效洞口/hm2,最佳防治指标115.00有效洞口/hm2,符合"得>失"的防治原则。

摘 要：
The economic loss level caused by Meriones unguiculatus and its control index were studied in the desert steppe in Haziliang Village of Dingbian County,Shaanxi Province.The results showed that the population density of M.unguiculatus was positively related with forage yield and economic loss(R=0.938),and the average relative population density was 645.93 effective holes/ha,and the average economic loss was 228.69 yuan/ha.The linear regression equation between the number of effective holes(X)and hay yield loss(M)was:M=0.836 X-32.10.Bromadiolone was used to control at large scale and cost was 42.75yuan/ha,the control effect was 73.34%,control benefit was 167.72 yuan/ha,and the input-output ratio was 1:3.92,the allowed economic loss rate was 8%,which accounts for about one quarter of the actual economic loss(31.42%).The best control index was 115 effective holes/ha,and the economic loss level was 193.46 effective holes/ha.
