The results showed TN, TP load reached the maximum around 30 to 45 days at the same level of straw into Dianchi Lake, which flower strow significantly higher t han the vegetable st row in the werter TN, TP the total release . Linear regression amalysis of di fferent inputs levels of straw indicated that, Dianchi Lake TN, TP concentration and 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 百• kgT ; the TN Pol lution 1 oad of vegetable straw is 41. 16 g • kg~l, TP pollution load is g
