Determining the Extent and Condition of Riparian Zones in Alternative Drinking Water Supply of Xiquanyan Reservoir, China

Abstract:

Riparian buffer zones (RBZ) plays important roles in the quality of surface water, the width and the connection of RBZ are related with the pollution removal effect. This paper evaluates the RBZ conditions in the basin of Xiquanyan reservoir which is an alternative drinking water supply reservoir. Using the software of ENVI to extract the RBZ distribution map from the image of Landsat 8; GIS and Fragstats were used to evaluate the status of RBZ. Divide the basin of Xiquanyan reservoir in to four divisions. The river lengthy, areas, average width of RBZ, SD, AI, and CONTAG were identified in each division. The result shows: (1) The total area of RBZ in the basin of Xiquanyan reservoir is adequate; however, the distribution of RBZ is uneven, part of it is too large, part of it is too small; (2) the connection of RBZ is good in part of the basin, it needs to improve the quality in the fourth division, western part of the Xiquanyan reservoir.
