| 英文简介 | The natural euphrates poplar forests is the principal part to protect the desert ecosystem around Tarim river basin, but a large area of euphrates poplar forests die of apocheima cinerarius every year, which worsens the ecological damage.Hyperspectral remote sensing is a kind of effective method to monitor insect pests,however, the research on hyperspectral monitoring mechanism and evaluation model of hazard index through ground experiment is the prerequisite of the specific application.So this project takes apocheima cinerarius which is most serious pest in euphrates poplar forests in the southern arid area of Xinjiang as the research object，takes study on hyperspectral response of physiological changes and biochemical changes of the canopy which pests caused as the breakthrough point through factitious mutagenic experiment of pests and hyperspectral reflectance data, physiological data, biochemical data of the canopy and data on drought. Correlation analysis, principal component analysis, wavelet analysis, regression analysis and discriminant analysis methods will be used to study the changes of the hyperspectral data which pests caused, discuss and find hyperspectral monitoring mechanism of insect pests,reveal the influence law of drought on hyperspectral characteristics of pest monitoring,build hyperspectral feature library of pest monitoring,and establish a model estimating physiological and biochemical parameters and a model evaluating hazard index of pests which are suitable for different drought index in the south of xinjiang.And then,the research results can provide theoretical basis and basic data for the application of hyperspectral remote sensing technology in montoring insect pest in the southern arid area of Xinjiang,provide some guidance for accurate spraying of Aircraft control program about apocheima cinerarius in natural euphrates poplar forests in xinjiang as well. |
