| 中文摘要: |
| 2010年4月至9月以巢湖富磷地质区池塘为实验对象，测定了叶绿素a与不同形态磷的浓度以及藻类的数量和组成，分析了沉积物藻类可利用性磷（AAP）含量与磷平衡浓度，提取并用分子生物学方法鉴定了沉积物无机磷细菌的主要种类。结果表明：沉积物AAP含量、溶解总磷和叶绿素a浓度均显著正相关。沉积物磷在吸附和释放趋势上基本对应于藻类随季节消长的模式。藻的种类较丰富，沉积物无机磷细菌的主要种类包括微单胞菌（Micromonospora sp.R1、Micromonospora chokoriensis）和链霉菌（ Streptomyces neyagawaensis、Streptomyces torulosus）。微生物驱动的富磷地质区沉积物磷的溶解可为藻类的生长提供生物可利用的磷营养。 |
| 英文摘要: |
| Chlorophyll a and various phosphorus forms concentration、the abundance and composition of Algal、Algae Available Phosphorus(AAP) and equilibrium phosphorus concentration(EPC0) were addressed systematically from April to September in 2010, targeting phosphate mine region of Lake Chaohu. Extract and identified the main types of sediment inorganic phosphate-solubilizing bacteria using molecular methods. The results indicated that Chlorophyll a and Dissolved Total Phosphorus(DTP)，Algae Available Phosphorus(AAP) were significant positive correlation. The tendency of sediment phosphorus adsorption and release basically corresponds to the pattern of seasonal fluctuation of the algae. This region was abundant in types of algae. The main types of sediment inorganic phosphate-solubilizing bacteria including Micromonospora sp.R1、 Micromonospora chokoriensis、Streptomyces neyagawaensis、Streptomyces torulosus. The microbial-driven phosphorus release in phosphorus-rich geological region can supply bioavailable phosphorus for the growth of algae |
