摘要:

利用2006年4月6~7日在甘肃省庆阳市境内环江、柔远河和马莲河实测的石油类污染水体波谱数据,以及石油类污染测定数据,采用Fisher判别分析方法,建立了基于地面实测光谱数据并适用于本研究区域的水环境石油类污染遥感识别模式,并利用2006年10月15~17日重复观测的数据进行精度验证,结果表明精度可达89%;将该模式应用于2005年10月16日和2006年4月10日过境的两景Landsat/TM图像;根据遥感模式反演结果图,对该区域水环境石油类污染的时空变化进行了分析。水环境石油类污染遥感模式的建立为从遥感影像上快速、大面积获取石油类污染信息提供了一种技术手段。

Abstract:

This work was to give an identification mode of petroleum pollution concentration within water body using remotely sensing technique. For this purpose the field data, including the spectral data of water body and the petroleum pollution concentration within water, were collected at Huanjiang river, Rouyuan river and Malian river in Qingyang city, Gansu province from April 6 to April 7,2006 and from October 15 to October 17,2006. The samples collected in the first field were employed to establish the identification mode of petroleum pollution concentration according to Fisher multiclass discriminant rule. By the actual status and the national standard, the petroleum concentration were classed three level. The field spectral
data were processed as corresponding bands of Landsat/TM. And the petroleum concentration can be identified as the following equations
class1=-132.003TM1+1088.964TM2-613.444TM3+113.629TM4 (1)class2=-108.2TM1+1135.458TM2-645.701TM3+87.264TM4 (2)class3=9.369TM1+1018.522TM2-619.677TM3+89.38283TM4 (3)Where TM1, TM2, TM3, TM4 are respectively the corresponding band of Landsat/TM, and class1,class2, class3 represent three level of petroleum concentration. The accuracy reaches 89% with the validation of the samples collected in the secondary field. Further, the model was applied to the two Landsat/TM images collected on Oct. 16, 2005 and Apr. 10, 2006 in order to obtain the distributing image of petroleum pollution concentration in the rivers. By mean of the image the temporal change and spatial distribute of the petroleum concentration within the three rivers were analyzed. The result shows that the establishment of identification mode based on remotely sensing provides an effective means to obtain rapidly and low-cost the concentration of petroleum pollution concentration in water environment.

Key words: Petroleum concentration    Water spectra    Fisher multiclass discriminant rule    Remotely sensing identification mode
