摘要:
选择封丘试区内有代表性的7类水体,对其营养状态进行综合评价和聚类分析,初步提出了用于水体营养状态评价的方法和标准。结果表明:各水体营养状态可依其植物组成而明显分成挺水植物、沉水植物和浮游植物型等,而且草型水体的营养指数均高于藻型水体。总的看来,该试区各类水体营养状态较为相似,营养指数均很高,属富营养-重富营养型,渔业发展潜力较大。

Abstract:
Comprehensive evaluation and cluster analysis of trophic state were made on seven representative aquatic systems in the Fengqiu Experimental area.Based on the vegetation, the aquatic systems can be divided into emergent-macrophyte type,submerged-macrophyte type and phytoplankton type.The trophic indices of the macrophyte-type waters were higher than those of the phytoplankton type waters.In general, the trophic states of various aquatic systems were rather similar to each other with high indices.Thus, the waters are eutrophic or even hypereutrophic, possessing great potential for fishery development, A brief account on the standards and methods for the evaluation of trophic state of water bodies is given.
