| 摘 要： | 将航天遥感技术运用于森林病虫害调查区划中。应用松毛虫大发生时的资源卫星照片,开展了外业调查,建立了地面判读特征。用同一地区松毛虫发生前后的资源、气象卫星资料和林相图、地形图等作为区划时参考,并研究和建立了落叶松毛虫发生与立地条件相关的数学模型,在以上基础上对100万hm~2的地域进行了松毛虫不同程度危害面积的区划,精度达到90％。

| Abstract: | The space remote sensing technology is applied to the investigate division of forest pests in the study. The natural resources satellite photographs are got when a vast amount of Dendrolimus superans butler happened are applied to do outside investigate and establish ground explanatory translate mark. The natural sources, the meteorological satellite material sources, the forest map and the topographic map before and after Dendrolimus Superans Butler happened on the same area are consulted to divide. The mathematics model that is bearing to happen Dendrolimus Superans Butler with site condition are studied and established. On the above base, the division of Dendrolimus Superans Butler harm degree and area are taken million hectares areas. The precision is ninty per cent. |
