| 1 | 中国主要土壤高光谱反射特性分类与有机质光谱预测模型显示文摘土壤可见-近红外漫反射光谱是当前对地遥感观察和土壤近地传感器研究的重要方向,同时也被认为是土壤数字制图、精确农业和土壤资源调查等方面最重要的数据获取技术. 从中国西藏、新疆、黑龙江、海南等地采集16种土类的1581个土壤样本,经干燥过筛后统一采用 ASD光谱仪测量了其室内可见-近红外反射光谱(350-2500 nm). 对所有的土壤光谱数据采用Savitzky-Golay平滑加一阶微分进行转换,来减少大样本数据受到实验室光学测试环境条件差异的影响,然后对数据进行主成分变换降维处理. 引入模糊k-means方法进行大样本光谱数据的最佳分类数目计算,并将中国土壤光谱数据分成五类,各自代表了不同的土壤矿物和有机组分,主要类型与国际同行类似成果有可比性. 最后提出了采用土壤光谱分类方法结合偏最小二乘回归法(PLSR)方法建立土壤有机质的光谱分类-局部预测模型,结果比未分类直接采用PLSR方法的一阶微分-全局预测模型的精度有了显著提高,其预测模型的R2和RPD两个指数分别从0.697和1.817提高到0.899和3.158. | 史舟 王乾龙 彭杰 纪文君 刘焕军 李曦 Raphael A VISCARRA ROSSEL | 2014 | 中国科学:地球科学2014，44，5： | 100 |
| 2 | Development of a national VNIR soil-spectral library for soil classification and prediction of organic matter concentrations显示文摘Soil visible-near infrared diffuse reflectance spectroscopy(vis-NIR DRS)has become an important area of research in the fields of remote and proximal soil sensing.The technique is considered to be particularly useful for acquiring data for soil digital mapping,precision agriculture and soil survey.In this study,1581 soil samples were collected from 14 provinces in China,including Tibet,Xinjiang,Heilongjiang,and Hainan.The samples represent 16 soil groups of the Genetic Soil Classification of China.After air-drying and sieving,the diffuse reflectance spectra of the samples were measured under laboratory conditions in the range between 350 and 2500 nm using a portable vis-NIR spectrometer.All the soil spectra were smoothed using the Savitzky-Golay method with first derivatives before performing multivariate data analyses.The spectra were compressed using principal components analysis and the fuzzy k-means method was used to calculate the optimal soil spectral classification.The scores of the principal component analyses were classified into five clusters that describe the mineral and organic composition of the soils.The results on the classification of the spectra are comparable to the results of other similar research.Spectroscopic predictions of soil organic matter concentrations used a combination of the soil spectral classification with multivariate calibration using partial least squares regression(PLSR).This combination significantly improved the predictions of soil organic matter(R2=0.899;RPD=3.158)compared with using PLSR alone(R2=0.697;RPD=1.817). | SHI Zhou WANG QianLong PENG Jie JI WenJun LIU HuanJun LI Xi Raphael A VISCARRA ROSSEL | 2014 | Science China Earth Sciences2014，57，7： | 32 |
