中文摘要精准农业是21世纪农业科技发展的前沿,是实现农业优质、高产、低耗和环保的有效途径。遥感技术在精准农业中起着重要的作用,它可以为精准农业提供大量的田间时空变化信息,对棉花长势进行动态的监测。运用高光谱处理技术将遥感生理生化信息定量化,及时了解棉花的生长状况,进行各种补救措施,调配水肥供给,保证棉花的正常生长。此外,可以及时掌握天气现象对棉花生长的影响以及病虫害对产量造成的损失等,为农业政策的制定和粮食贸易提供决策依据。本文主要介绍了利用遥感提取棉花种植面积,长势,生理生化参数的方法,并结合具体的实例进行了分析。全文主要分为以下七个部分:第一部分首先介绍了精准农业的基本概念,以及遥感技术与精准农业之间的关系,和国内外的研究进展。第二部分介绍了遥感在精准农业中的应用技术体系,分析了目前在精准农业中常用的一些遥感数据源,介绍了本文中所运用的主要处理方法和技术路线。第三部分详细介绍了利用遥感的手段提取棉花种植面积信息的方法。主要采用以目视解译为主,计算机图像分类,图像运算为辅的遥感分析的方法。第四部分介绍了利用MODIS数据进行棉花长势信息提取的方法。通过NDvi的时间序列来分析棉花长势情况。一些特点,并对不同生育时期、不同水分胁迫、不同氮素胁迫下的棉花光谱迸行了分析。同时介绍了利用高光谱数据对棉花生物物理、生物化字蚕数进仃提取的方法。以实例分析的方式,对农八师棉花种植面积,棉花长势和棉花生物物理、生物化学参数进行了提取,结果表明遥感在棉花精准种植中具有巨大潜力。第七部分对本文的研究工作做出了总结,并结合遥感应用的现状,指出了今后遥感在精准种植应用中的发展方向。Precision agriculture is the front of agricultural science and technology in 21st century, and also is the effective way of high-quality, high yield, agriculture, low consumption and environmental protection., The remote sensing technology plays an very important role in precision agriculture, it can offer a large number of change information of field space-time for precision agriculture, carry on dynamic monitoring to the growing situation of the cotton. Using high spectrum treatment technology take remote sensing physiology biochemical information ration, understand the growth state of the cotton in time, carry on various kinds of remedies and allocate the water and manure to supply, guarantee the normal growth of the cotton. In addition, can master weather phenomenon the influence that the cotton grows and loss that plant diseases and insect pests cause to the output ,etc. correctly in time, offer the decision basis for formulation of the agricultural policy and grain trade. The main introduction to this text utilizes remote sensing to draw the cultivated area of the cotton, growing situation, the biochemical parameter method of the physiology, combine the concrete instance to analyse. This paper is divided into seven following parts mainly: Chapter One At first, introduce the basic conception of precision agriculture, and the relation between remote sensing technology and precision agriculture, with domestic and international research progress. Chapter Two Introduce the application technology system of remote sensing in precision agriculture, analysis some commonly used remote sensing data sources in precision agriculture at present, and introduced a main treatment method and technological route used in the article. Chapter Three Introduce the method of drawing the cultivated area information of the cotton by remote sensing. Adopt mainly manual interpretation, as well as the method of image classification and image operation is complemented in image manipulation Chapter Four Introduce the method of using MODIS data to draw the growing situation information of the cotton and analysis it through the time series of NDVI. Chapter Five Introduce the spectrum character of cotton, and analysis the spectrum in different period, and under water stress and nitrogen stress condition the same time introduce the method of estimating main cultivation physiology parameters of cotton by using hyperspectral remote sensing. Chapter Six Combine the method introduced in front in this paper, give some example of estimating the cultivated area, the growing situation and some physiology parameters of cotton. The result indicates that remote sensing has enormous potentiality in cotton precision agriculture. Chapter Seven Summarize to the research work of this paper, combine the current situation of the remote sensing application, point out the developing direction of remote sensing in precision agriculture in the future.
