Xinjiang Cotton Remote Sensing Monitor Recognition Method And Model Study

And unceasingly consummates along with the Xinjiang cotton remote sensing monitor system establishment movement, comprehensive, is fast, the objective monitor cotton sown area and the growing trend, has the vital significance to the Xingjian agricultural management department and the economy control section decision-making, But in this monitor system, regarding cotton's fast accurate recognition also is the foundation and a key link, this research take he northern border Shihezi reclaimed district and east the boundary Hami reclamation area as the research area, has conducted the preliminary study to the cotton remote sensing monitor recognition pattern, the main content includes:1,Has carried on the determination to two research areas staple crop ground spectrum index of reflection2,To two research areas crops spectrum data which determines has carried on the data processing and the analysis, used up the spectrometer to bring tool and so on software and excel to four wave bands indices of reflection which planned to use has carried on the average and has made the corresponding booklet graph3,Initially had determined northern border area cotton remote sensing recognition best when for September in last ten days of the month, good when for June in the last ten days of the month, east the boundary area cotton remote sensing recognition is best when is mid-September, good when for June in last ten days of the month4,To studied in the area remote sensing picture the crops spectrum data to carry on processing and the characteristic analysis5,Finally had determined northern border area cotton remote sensing monitor best when is mid-September, east the boundary area remote sensing monitor is best when for late August6,Carried on to two research areas various crops' various wave bands spectrum characteristic has analyzed and has established based on the spectrum characteristic cotton remote sensing recognition model, and has carried on the precision confirmation to the model The above research institute establishes model precision quite high, has in the certain criterion scope the feasibility, has provided based on the spectrum characteristic method for the next Xinjiang cotton remote sensing monitor recognition further research and the quite important foundational data, because studies the region slightly, the spectrometry time cycle relative is shorter and so on the factor, also waits for to the great criterion scope cotton remote sensing recognition further studies and the confirmation...
