Differeht rocks in Duobaoshan area have their respective characteristic spectra,which are very helpful to the explanation of remote sensing data and the search for copper deposits by remote sensing technology. Reflective spectrum characteristics of rocks in the area were studied with the field spectometer RS-II (or IRIS)。The paper points out that the reflectivity (p) of rocks in Duo-baoshan area decreases in order of Hercynian magmatic rocks, Paleozojc strata,and Hercynian volcanic rocks.The analysis of the reflective spectrum charac-teristics shows that the reflectivity of Hercynian inagmatic rocks is related to their alteration and Cu content. The magmatite alteration related to the ore-forming process of the Duobaoshan copper deposit is noted for the characteristic spectrum of 0.70μm band. The paulopost alteration caused by thermal fluid in magmatic rocks has distinct soectra at 1.4μm,1.9μm and 2.2μm respectively.The reflectivity of volcanic rocks is directly proportional to their SiO_2 and Cu content. The paper holds that 0.76-0.9μm,1. 55-1.95μm and 2.08-2. 35μm are better bands in search for volcanic rocks.The reflectivity of paleozoic strata in the area is inversely proportional to C content and number of characteristic spectra. The Ca content and CO radicals are directly proportional to number and intensity of characteristic spectra.The authors have discussed the application of reflective spectra of rocks in Duobaoshan, and point out that the study of reflective spectrum features of rocks can be used to select the best band and the best ratio band for proc-essing Landsat image. The present paper has indicated that the stacking of ground spectra is one of the best methods to define the band for processing TM image.

黑龙江多宝山地区岩石反射波谱研究表明,海西期岩浆岩反射率(ρ)最高,古生代地层次之,火山熔岩最小,岩浆岩中ρ值大则蚀变作用强,ρ值变化大则蚀变类型多,0.70μm谱是岩浆岩蚀变作用显著与否的标志,岩石经热流体后期改造作用后产生强的1.40、1.90和2.20μm特征谱。火山熔岩ρ值与SiO_2含量呈正相关,其铜含量高、蚀变作用强则ρ值变化大,ρ值在NIR区差异最大并形成三个优选窗口。古生代地层ρ值与碳含量、特征谱数呈负相关,Ca含量、基团与特征谱数、强度呈正相关。据岩石波谱数据及其计算值,文章演绎出地面波谱叠合法并综合其他方法确定了区内TM图像处理的最佳波段组合。

Some models for estimating chlorophyll concentration are developed in this study by taking Daya Bay as an experimental site and Landsat-5 TM (Thematic Mapper) data as information resources, and combining the survey data of chlorophyll concentration in the surface coastal water. On the base of studying the spectral characteristics of chlorophyll and the mechanism of surveying chlorophyll concentration using remote sensing data, taking 75 band compositions of TM1-TM4 bands as the subfactors and the chlorophyll concentration as the mother factor, factor analysis was carried out by using the Grey System Theory. According to the results of the factor analysis, 5 band compositions, which have greater correlative degree to the mother factor, are selected for modeling. The error analysis shows that these models have high accuracy with the mean absolute relative error less than 11. 2% and relative standard error less than 6. 7%. Unlike the general way taking the ratio of TM2 or TM3 to TM1 as the best band compositions, this study shows that (TM3×TM4) is the best band composition for estimating chlorophyll concentration of the surface layer of coastal water, and the estimated accuracy can not be advanced by using the ratio of (TM3×TM4) to TM1 or TM2 or In(TM1+TM2) or In(TM1×TM2).

本研究以大亚湾为实验区,以陆地卫星TM数据为信息源,结合表层海水叶绿素浓度实测资料建立模型。在对叶绿素光谱特征及遥感估算叶绿素浓度机理研究基础上,选取了TMI—TM4波段的75种波段组合为子因素,以叶绿素浓度为母因素,利用灰色系统理论,分析各波段组合与叶绿素浓度之间的关联度。将关联度最大的5种波段组合分别建模,得到5个估算表层海水叶绿素浓度的反演模型。误差分析表明,各模型的最大相对误差在19%以下,平均绝对相对误差在11.2%以下,相对标准误差在6.7%以下,模型精度较高。研究表明:(TM3×TM4)是估算沿岸海水表层叶绿素浓度的最佳波段组合,采用(TM3×TM4)与TM1、TM2或ln(TM十TM2)、In(TM1×TM2)之比值并不能改善估算精度。
