Paper Abstract

Nansihu lakes are important water conservancy hinge on the east line project of Translating South Water to North. In this paper, associating with the environment investigation and estimation on the south west of Shandong, we have a dynamic detection on their water quality and water areas with remote sensing covering more than 1300 kilometers. Using the data getting at low water time (Mar.28.2001 CBERS-CCD) as well as at abundant water time (Sep.6.1994 TM), combining with sampling test data on the spot and other remote sensing information, we have an iterative classification on images getting at different time. The result shows that the difference of regional water areas above the Second Level Dams of Nansihu lakes is about 169 square kilometers between low water time and abundant water time. From the images, three classes of water can be separated, including great area wet land. The area of the first class water is 13.3 square kilometers, the second class is 102.7 square kilometers, and the third class is 345.5 square kilometers. All these classes have an obvious relativity with the chemical indexes of water pollution, such as Biology Oxygen Demand (BOD) and Dissolved Oxygen (DO) and Suspended Substance (SS), etc.
