农田害鼠的生态控制及其预测预报技术进展

1983年以来，我国已建成90个农田鼠情测报点，形成测报网络亦开展常年系统监测；进行了鼠种分布调查，基本查清了当地的鼠种及其分布、危害，并绘出地理分布区划图。对小型鼠种以臼齿磨损程度作为划分种群五个年龄组的相对指标，简便可靠。防治对策由单纯化学防治，逐步走向以生态控制为主的综合防治。近年来通过环境、农业措施（包括天敌）控制，以抑制鼠害发生的生态学途径已普遍受到重视，并已取得成效。

THE ADVANCE OF ECOLOGICAL CONTROL AND FORECAST OF THE DAMAGE BY RODENT IN FIELD

Since 1983, 90 forecasting regional stations for rodent population survey have been established. As a forecasting system, a series of supervision of rodent demage is carried on in ordinary year. The taxanomy, and distribution or damage of rodent, have been surveyed in these regional stations, and they have obtained a lot of results. A geographical distribution map for zoning has been drawn, The abrasion degree of small rodent molar is the moderate target for classification of rodent species community in 5 different age groups. Ecological control, instead of chemical control, will be the most important measure of an integrated management for rodent damage. In recent years, the ecological control (including environmental improvement, protection of natural enemy, and other agricultural practices) has been proved very effective in eliminating the rodent damage.
