standing crops
stock on hand
Examples
- The results showed that microzoop1ankton could controi the quantity of phytoplankton in xiamen west harbor , preventing the formation of algae bloom
57 ，摄食浮游植物现存量的22 45 ，对浮游植物有一定的控制作用。 - Standing crop the total weight of all the living organisms present in an ecosystem at a given moment , usually expressed as dry weight per unit area
现存量：某一给定时刻，生态系统中所有活的有机体的总重量。通常的表述是单位区域的干重。 - Taxonomic groups of zoobenthos were significantly correlated with biomass of submersed aquatic macrophytes , depths , secchi disk transparencies , total phosphorus and total nitrogen contents
底栖动物各个类群的现存量与水草生物量、水深、透明度、总磷和总氮的关系均较密切。 - For the relationships between zoobenthos and environmental factors , results showed that zoobenthic standing crops were positively correlated with submersed aquatic macrophytes , total phosphorus and total nitrogen contents but were negatively correlated with depths and secchi disk transparencies
环境分析表明底栖动物总的现存量与水草生物量、总磷总氮含量均正相关，与水深、透明度均负相关。 - But the gut evacuation rates did not vary with the experimental temperature and body size . copepods usually performed feeding rhythms with maximum level at midnight and their feeding activities changed with the tide rhythms at the estuary area . in the laizhou bay , the daily grazing rate of the copepod population on phytoplankton was 20 . 81 ? 98 . 35 % of the primary production and 2 . 53 ? 6 . 36 % of the phytoplankton standing stock in summer
现场测得的桡足类摄食率结果表明，在莱州湾，夏季桡足类群体的日摄食量占初级生产力的20 . 81 ? 98 . 35 % ，占浮游植物现存量的2 . 53 ? 6 . 36 % ，潍河口，河口外浮游动物优势种群体的日摄食量占初级生产力的32 . 28 % ，占浮游植物现存量的14 . 12 % ，河口内对初级生产力的摄食压力< 3 % ，日摄食量小于浮游植物现存量的1 % 。
