It demonstrated that there were two Chl. a pinnacle at spring and autumn in two years in five ponds,and two low Chl. a "valley" at hot summer and winter. Thewinter’ s "valley" was lower than summer’s. The average Chl. a and its pinnacle in 1989were higher than that in 1988. The seasonal aspect changings of Chl. a were obviously different among 5 ponds. Using relation—regression analysison Chl. a and water emperature, Chl. a and phosphorus of various state, we found that either water temperature or phosphorus had different influence on algal growth among 5 ponds,and phosphorus had served as a limit or control factor to algal growth in No. 5 pond. 复合氧化塘 叶绿素a 季相变化 相关回归分析 complex oxidation pond chlorophyll — a seasonal aspect changing relation — regression analysis Q89;X171 国家“七五”科技攻关项目基金 1993-03-01 2021-04-01 3
