克里雅河流域土壤盐分光谱定量分析

本文对克里雅河流域进行野外调查、采集土壤样品及其光谱反射特性的测量,通过比较不同光谱预处理的方法建立偏最小二乘回归(PLSR)模型,并利用决定系数(R2)、均方根误差(RMSEP)、残留预测偏差(RPD)对模型的稳定性和预测能力进行检验。结果表明:反射率一阶微分是预测土壤样本盐分含量的最佳光谱指标。PLSR模型在建立土壤光谱与盐分含量关系时较为适用,R2、RMSE和RPD分别为0.77、0.25和1.88。利用反射光谱估算土壤中盐分含量,通过各种光谱预处理方法可以提高估算精度,可以为该区土壤盐渍化评价和生态环境调查提供依据。

利用新疆奇台县荒漠-绿洲交错带的75个土壤样本,选取土壤可见光-近红外光谱的反射率（R）、光谱反射率倒数之对数（lg（1/R））、光谱反射率一阶导数（FDR）和光谱波段深度（Depth）4个指标,分析了其与土壤N、P、K元素含量的关系,分别建立了反演模型并对其精度进行了检验。结果表明：可见光-近红外反射光谱快速估算荒漠-绿洲交错带土壤N、P、K元素含量的潜力大,其预测精度由高到低的排列顺序为：N>P>K。不同光谱指标反演模型的精度各异,指标Depth和FDR的预测效果明显优于lg（1/R）和R,对N和P元素的拟合效果为：lg（1/R）相似文献   

若尔盖湿地土壤重金属元素含量的遥感反演

土壤中的重金属元素对植物和动物具有一定的毒害作用,测量湿地土壤重金属元素含量,对评估湿地生态系统健康具有重要意义。以光谱分辨率的优势,高光谱遥感可以获取地物的连续光谱信息,可应用于土壤研究。以四川若尔盖国际重要湿地为研究区,在研究区中采集土样,测定土样的5种重金属元素含量;利用偏最小二乘回归(partial least squares regression,PLSR)方法,分析了环境一号卫星上搭载的超光谱成像仪(hyperspectral imaging radiometer,HSI)的地表反射率数据与实测的土壤重金属元素含量的关系;利用原始地表反射率及原始地表反射率曲线的一阶微分值和倒数的对数值,分别建立了预测土壤中5种重金属含量的3个回归模型。结果表明,土壤锌含量的平均值(62.83 mg/kg)最高,镉含量的平均值(0.18 mg/kg)最小;土壤锌含量与铅、铬含量显著相关,土壤铬含量与铜、铅含量显著相关;在3个回归模型中,利用一阶微分值所建立的模型的预测效果最好,土壤5种重金属含量的实测值与预测值都显著相关,其次是利用原始反射率所建立的模型,而利用倒数的对数值所建立的模型的预测结果相对最差,尽管如此,除了镉和铅含量外,其它重金属元素含量的实测值与预测值也都显著相关。利用高光谱遥感技术反演土壤某些重金属元素含量具有可行性,有利于实时掌握湿地土壤重金属含量及其对湿地生态系统健康的影响。     

水分胁迫条件下棉花生理变化及其高光谱响应分析

利用ASD地物光谱仪,测定水分胁迫条件下棉花不同生育时期内叶片的光谱反射率,应用微分技术处理棉花的反射光谱,并结合棉花叶面积指数(LAI)、叶绿素(a b)含量(Chlt)、叶片全氮(TN)含量等生物参数进行分析,研究棉花水分胁迫情况下的高光谱特征,结果表明,一阶微分光谱720nm波段的数值与LAI的正相关(R=0．7656);750nm处一阶微分值与叶绿素含量呈显著正相关关系(R=0．7774);微分光谱690nm～740nm数值积分面积与TN含量呈正相关(R=0．7669),采用比值反射率对反射光谱1300nm～1500nm波段范围内最小值与棉花叶片的含水量作相关分析,达到极显著水平(R^2=0．8298),验证了一阶微分光谱数据与棉花的生理参数有很好的相关性,可见光和近红外波段光谱反射率能够反映出棉花生长发育的动态特征;证明了棉花的花铃期是高光谱遥感对棉花长势和生理参数定量诊断的最佳时期。本研究通过建立一系列线性光谱模型对棉花生理参数进行估测,为基于高光谱数据的棉花生长模型和棉花长势的遥感监测提供了理论依据。

土壤光谱反射特性的研究是土壤遥感的物理基础,土壤氧化铁含量影响土壤反射率。对采集的174个土样350~2 500 nm谱段的光谱数据进行分析,着重探讨下述3类光谱变量,寻找对土壤氧化铁含量敏感的光谱特征。1)原始光谱反射率及其各种变换形式;2)基于光谱吸收峰特征的变量,因为已知三价铁在870 nm附近有吸收峰存在,提取该吸收峰的面积、宽度、深度等变量;3)基于植被指数的变量,构建土壤氧化铁指数。研究结果表明,各类变量中土壤氧化铁指数对土壤氧化铁含量最敏感,建立相应的回归预测模型,模型拟合度R2为0.534。     

基于离子光谱特征波段反射率的土壤碱化指标反演模型

以新疆奇台地区碱化土壤为研究对象,通过分析碱化土壤实测光谱反射率曲线与八大离子、pH、碱化指标相互间的相关关系,建立基于离子光谱特征波段反射率的各碱化指标一元及多元光谱反演模型,并对其精度进行验证。结果显示:Na^+、CO_3^2-、HCO_3^-含量与光谱反射率正相关,最高点的相关系数分别为0.710、0.798、0.749,而Ca²⁺、Mg²⁺含量与光谱反射率负相关,相关系数最高均不超过-0.370,反映出前3类离子含量与光谱反射率关系更为密切。SAR(钠吸附比)和ESP(碱化度)与Na+相关系数同为0.954,TA(总碱度)、RSC(残余碳酸钠)、pH与CO_3^2-的相关系数分别为0.946、0.949和0.953,总体上Na^+和CO_3^2-含量对各碱化指标的影响更大。各碱化指标与土壤光谱反射率的相关性TA>RSC>ESP>pH>SAR;其中TA与光谱反射率的相关系数达到0.863。碱化指标TA的离子光谱特征波段反射率反演模型精度最好,其R^2为0.703,比利用实测光谱反射率建立的pH反演模型的R^2高约14%,说明前者精度更高,能更好地反映研究区内土壤的碱化程度。利用离子光谱特征波段反射率实现对土壤碱化的预测会成为今后研究的重点。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.

THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.
