水体污染遥感监测的可行性分析

地面水体污染监测技术向空间遥感监测方向的拓展，在常规的监测技术基础上增添了新的观察角度，同时也反映出在应用现代遥感新技术的过程中，面临着需要不断加强改进和提高遥感监测精确度的处理方法。虽然遥感技术可以较大程度地改善常规性区域跨度和时效性方面的不足，但是现阶段通过遥感技术所能够采集到的水质信息及其图像判读，无论是在硬件技术上还是在软件技术上，都仍然存在较大的潜力空间有待于进一步开拓，从实际应用的可操作性程度分析，遥感技术对水体污染监测在精度方面仍然难以完全替代地面人工的局部监测过程。遥感探测过程和图像处理判读等有关的研究成果表明，即使是对水污染特征值显像比较突出的水质项目，目前在地面监测与遥感空间探测之间仍然需要通过相互对照验证和互相补充，才能更精确地全面调查地表水体污染状况，因此客观认识遥感过程及其可应用范围，对于切实地分析水体污染遥感监测的具体问题具有重要的现实意义。

FEASIBILITY IN THE USE OF REMOTE SENSING FOR WATER POLLUTION ANALYSIS

With the techniques of remote sensing (RS) applied in the observation of the water pollution from the surface of the earth to space,the research method of normal water quality has got a new point of view beyond routinization,and it indicates that the modern technique should have the importance of the precision improved and enhanced while the process is outspreading. On the other hand,RS can improve the limited conditions of the normal scale span and time efficiency while techniques of RS are applied in observation of the water quality,it also exists a large potential technical space to be improved for the water pollution information collected from RS and image translation at the present stage,not only for hardware techniques but also for software techniques,and RS can not fill entirely in status of the normal surface water pollution monitoring because of the error based on grade analysis of the practicality operation. Many studies about the RS process and image translation indicate that the results from remote sensing should be validated and reinforced by surface complementarities,even for the extrusive water pollution items which appeared in the image strongly,the conditions of the water quality will be investigated fully and accurately. Therefore the authors described the RS presentation and discussed the techniques of RS process. It is important and useful to analyze items applied in water pollution research with impersonal cognition and detail scale range in the application practically.
