Quantification of non-point sources phosphorus pollution in key protection area of Taihu Lake

Abstract

Abstract: The distribution of various kinds of non-point sources phosphorus pollution in Xueyan Town,Wujin city,Taihu area was researched through field experiments and local investigation during rice growth season. The results showed that of all kinds of phosphorus pollution,about 56.2% (1313 kg P) abstract was from farmland,22.2% (518 kg P) abstract was from town residents,18.9% (442 kg P) abstract was from village residents,and 2.7%(62 kg P) abstractwas from livestock. Besides the strict control of the phosphorus pollution from farmland,attention should also be paid on the control of domestic water pollution from towns and villages.

Key words: Taihu Lake, Non-point sources pollution, Phosphorus, Quantification
