对虾养殖池沉积环境中TOC_TP_TN和pH及质量评价模型

１９９５年冬季，研究了青岛地区即墨市丰城、王村、城阳区上马、流亭等乡镇的对虾养殖区８０个虾池沉积物中有机碳（ＴＯＣ）、总氮（ＴＮ）、总磷（ＴＰ）和ｐＨ与池龄的关系。结果表明，沉积物中ＴＯＣ随年代而积累，除即墨丰城泥沙质虾池外，与池龄成正线性相关，相关系数（γ）为０．７４２２￣０．８３３０（Ｐ＜０．０５）；沉积物中ＴＮ亦随年代而积累，所有调查区沉积物中ＴＮ与池龄成正线性相关，相关系数（γ）为０．４６０３￣０．８５７４（Ｐ＜０．０５）；沉积物中ＴＰ随年代而降低，与池龄成负线性相关，城阳流亭养殖区的相关系统（γ）为０．４２６１（０．１＞Ｐ＞０．０５），其它养殖区（γ）为０．４９５６￣０．９０６０（Ｐ＜０．０５）。沉积物的ｐＨ与池龄的关系无规律可循。提出了虾池底质环境质量的评价模型。

TOC, TP, TN and pH in sediment environment of shrimp culture and quality assessment module

In order to explore the relationship between environment quality and virus disease, in winter of 1995, the concentrat ion of total organic carbon ( TOC) , total nitrogen ( TN) , total phosphorus ( TP) and pH in bottom sediments of 80 shrimp culture ponds in Qingdao of China were determined, and the correlation between TOC, TP, TN and pH and pond age was analyzed. The results showed that TOC , TN were positive linear correlation w ith pond age, the correlation coeff icient ( ..) for TOC was 0. 742 2- 0. 833 0 ( P < 0. 05) , the correlation coefficient ( ..) for TN was 0. 460 3- 0. 857 4 ( P< 0. 05) ; TP was negative linear correlation with pond age in Liuting areas of Chengyang with correlation coeff icient ( ..) of 0. 4261 ( P > 0. 05) , and was positive linear correlation in other area with correlation coef ficient ( ..) of 0. 495 6- 0. 906 0( P < 0. 05) . The relationship between pH and pond age was not regular. We suggested that the concentrat ion of TN as an index of pond soil quality. A assessment module was established for environmental quality of shrimp pond bottom.
