Characteristics of Temporal and Spatial Distribution of Water Quality in the Ponds of Lv-Tang-River National Urban Wetland Park, China

Abstract:

Based on the data collected in January, March,July and October in 2013, the characteristics of water quality in temporally and spatially in the ponds of Lv-Tang-River national urban wetland park were investigated. The results show that the main pollutants of Lv-Tang-River wetland are chemical oxygen demand, total nitrogen and ammonia nitrogen. Their average concentrations are worse than the national quality standards for Class V. The characteristics of water quality in spatially are significantly correlated with the plant configuration in the wetland. The water quality in reed pond is the best. Secondly is in natural pond. The worst is in lotus pond. The average of single parameter pollution index (S_j) of reed pond, natural pond and lotus pond is 1.72, 1.82 and 1.96. The water quality in the three ponds belongs to light pollution area. The water quality in July and October is better than that in January and March. In July and October, the water quality belongs to light pollution area and S_j is 1.12 and 1.35 respectively. In January and March, the water quality belongs to moderate pollution area and Sj is 2.17 and 2.71, respectively. In order to improve the water quality in Lv-Tang-River national urban wetland park and protect the ecological environment of Zhanjiang city, the valid measure is to strengthen the management of artificial ponds in winter and spring.
