摘要：By research on wetland water quality and nutrient distribution in sediments of Xixi Wetland,which is the first national wetland park in China,the results indicated that the water quality had been improved especially in Wuchang Creek and Deep Pond after sediment dredging.The other inspecting points were still bad and belonged to V or worse than V standard of water quality,which would not be qualified for the tourism.The total nitrogen and phosphorus contents were low in the surface sediments(0-20 cm) of wetland.The average contents of total nitrogen and phosphorus were 1.79 g·kg-1 and 0.80 g·kg-1 respectively.Spatially,the total nitrogen and phosphorus contents were lower in center wetland than that in outside.And it was the same situation in sediment dredging creeks.The distribution of nitrogen and phosphorus in sediments profiles indicated that the accumulation of nutrients had been reduced in center wetland,while it was improved in outside creeks which were disturbed by human activities more frequently.The total nitrogen and phosphorus contents in sediments of Xixi Wetland were lower than that in other wetland.However, the results of primarily assessment remind us of paying more attention to nutrient contents in sediments of Xixi Wetland,which had reached the environmental criterions.All the conclusions above would provide useful information for the farther reclamations of Xixi Wetland.
By research on wetland water quality and nutrient distribution in sediments of Xixi Wetland, WnlCn is me first national wetland park in China, the results indicated that the water quality had been improved especially in Wuchang Creek and Deep Pond after sediment dredging. The other inspecting points were still bad and belonged to V or worse than V standard of water quality, which would not be qualified for the tourism. The total nitrogen and phosphorus contents were low in the surface sediments （0 -20 cm ） of wetland. The average contents of total nitrogen and phosphorus were 1.79 g· kg^-1 and 0.80 g·kg^-1 respectively. Spatially, the total nitrogen and phosphorus contents were lower in center wetland than that in outside. And it was the same situation in sediment dredging creeks . The distribution of nitrogen and phosphorus in sediments profiles indicated that the accumulation of nutrients had been reduced in center wetland, while it was improved in outside creeks which were disturbed by human activities more frequently. The total nitrogen and phosphorus contents in sediments of Xixi Wetland were lower than that in other wetland. However, the results of primarily assessment remind us of paying more attention to nutrient contents in sediments of Xixi Wetland, which had reached the environmental criterions. All the conclusions above would provide useful information for the farther reclamations of Xixi Wetland.
