The straw of rural solid Waste are potential sources of water pollution in Dianchi Lake, six representative straws of rural solid Waste were selected to scientific estimate the TN, TP pollution load of Dianchi Lake Basin straw of rural solid Waste and study impact on water quality of Dianchi Lake. The resuIts showed that TN, TP load reached the maximum around 30 to 45 days at the same level of straw into Dianchi Lake, which flower strow significdntly higher than the vegetable strow in the water TN, TP the total release . Linear regression analysis of different inputs levels of straw indicated that, Dianchi Lake TN, TP concentration dnd inputs levels of straw is a significant positive correlation. The biggest potential pollution load of the straws of flower and vegetable into the Dianchi Lake are as follows: the TN Pollution load of flower straw is g • kg-1, TP pollution load is 23. 19 g • kg-1; the TN Pollution load of vegetable straw is 41. 16 g • kg-1, TP pollution load is 13. 56 g • kg-1.
