Abstract

The water quality of the inlets and outlets of Dianshan Lake was monitored annually. Likewise, a field experiment was conducted near Dianshan Lake to study the variations of nutrients in the surface water of experimental plots for various fertilizer treatments. The results indicated that the average contents of NH$_{3}$-Nandtotal P (TP) of the water in Dianshan Lake were 0.47 and 0.13 mg/L, respectively, which only met the Class Ⅴ level specified by the China Surface Water Environmental Quality Standard. The water quality of the inlets of Dianshan Lake varied from site to site and was generally worse than the water quality of the outlets. Further study found close correlations between the annual variations of nutrients in Dianshan Lake and the variations in the surface water of the rice fields. This suggests that the water quality of the lake was strongly influenced by diffuse agricultural pollution from the rice fields surrounding the lake. Therefore, to improve the water quality of Dianshan Lake further, it is highly important to reduce and control the diffuse agricultural pollution.

Key words： Dianshan Lake; NH$_{3}$-N; P; paddy field; diffuse agricultural pollution
