【摘要】 探讨了通过航空录像技术获取林木健康信息及手持式GPS地面定位变色树木的方法。结果表明,遥感监测所获取的地面变色的树木数据资料能够较为准确地与地面对应。利用该方法能够对有松材线虫病症状的松林准确、快速定位,从而起到及时监测疫情的作用。更多还原

【Abstract】 The methods to obtain the tree information by aerial remote sensing technique and locate the position of(diseased) trees by portable GPS were studied.The result indicated that the data of(discoloured) trees acquired by remote sensing monitoring could be well used in acurately locating its position.Namely,if the red symptom of pine wood nematode disease on pines appear,we’ll accurately locate the position of the trees and supervise the epidemic situation of the disease in time by remote sensing monitoring.更多还原
