近23 a气候变化对东平湖水位及TN、TP的影响
Effect of Climate Change on Water Level and TN and TP in Dongping Lake in the Past 23 Years
摘要
Abstract
Based on the meteorological,water level and water quality data in Dongping Lake in the past 23 years,the author analyzed the dynamic variation of water level and water quality and the correlation with meteorological elements under the conditions of global warming. The results show that the annual average temperature is increased,but the annual precipitation has a significant decline in the past 23 years;Mann-Kendall mutation test shows that the abrupt change of average annual temperature and annual average precipitation occur in 1997 and 1995;the annual mean water level of Dongping lake is 42. 72 m from 1990 to 2012 and it generally has been non-significant increasing;phosphorus is the main restriction for eutrophication of Dongping lake;the annual average temperature and annual precipitation have little impact on water level;the annual average precipitation has a significant impact on TN and TP,showing positive correlation.关键词
