China Aero Geophysical Survey and Remote Sensing Center for Land and Resources,Beijing 100083,ChinaIt is a difficult task for shadow and feculent water area processing when extracting water body from remote sensing image by traditional methods.Light Laser Detection and Ranging is robust to gain point cloudy data from shadow and feculent water as it has less affection from that area.However,the point cloudy data is always with low resolution which results to contour line with low accuracy.

从遥感影像中提取水体的传统方法在阴影处和水体浑浊处存在一定局限；机载激光雷达获取点云数据时水体受阴影和浑浊的影响小，因此使用点云数据提取水体比使用影像数据更加稳健；但点云数据的分辨率低，所提取的轮廓线精度不高。

The results showed that at the anaerobic phase, the PHB concentration in the cell and orthophosphate concentration of the anaerobic effluent obviously increased, the poly-P concentration in the cell decreased, and the cucci and bacilli with a size of 1.0~1.5 μm were dominant and formed grapy cellular cluster. At the anoxic phase, the PHB concentration and orthophosphate concentration decreased significantly, the amount of poly-P increased, and the elliptical cucci of 0.5~1 μm and spheral bacilli of 1.0~1.5 μm were dominant. At the aerobic phase, the PHB and orthophosphate concentration almost reduced to zero, the poly-P increased significantly, cucci appeared single or in pair, and the contour of sphere was blur and almost disappeared.

试验结果表明，在厌氧阶段，微生物细胞内PHB的量大幅提高，上清液中磷酸盐的含量上升，聚磷酸盐含量明显下降，粒径为1～1.5 μm、呈球状和棒状的菌群构成的葡萄状细胞簇占居优势；在缺氧阶段，微生物细胞内PHB的量下降，上清液中磷酸盐含量下降，聚磷酸盐含量上升，粒径为0.5～1 μm的椭球菌与1.0～1.5 μm的球杆菌占优势；在好氧阶段，微生物细胞内PHB的量较低或接近零，上清液中磷酸盐的含量接近零，聚磷酸盐含量明显上升，此时粒径1.0～1.5 μm的球菌以单个或成对出现，球菌不再饱满，呈现接近消失的状态。
