利用遥感抽样技术进行腾冲林地调查

Forest land inventory of Tengchong with remote sensing sampling

    摘要
  • 摘要: 当前我们所而临的严重问题之一是生态环境的恶化仍在继续发展。因此,除协调土地利用,争取更集约化的经营之外,由于森林资源是生态平衡的杠杆,所以森林资源的现状就必须更为精确地加以测定。

     

    Abstract: An experiment of the forest land inventory was made by means of the air photographs and LANDSAT remotely sensed images with unequal probability sampling in Tengchong county,Yunnan province.The unequal probability sampling is designed in variable probability,i.c.,sampling with probability proportional to size.The land area is calculated from the statistical model:A=1/n ??? ai/pi Here,n is the sample size.pi is the probability.ai is the sample datum.The techaique is available in practice for the experiment is successful.
