摘要
对小窑湾双壳贝类筏式养殖海区叶绿素a、海洋初级生产力的调查时认为:贝类养殖密度对叶绿素a值影响较大,从调查站位上看,养殖密度越大,其叶绿素a值相对较低,从养殖海区的季节变化上来看,叶绿素a值与海区双壳贝类的现存量密切有关;而初级生产力除与叶绿素有关外,还与该海区养殖品种收获时的人为扰动有关。
The fact that chlorophylla level and primary production were determined in shellfish raft cultivation area in Xiaoyao Bay in Dalian indicated that there was significant effect of shellfish cultivation on chlorophylla-a levels and primary production,that is ,chlorophylla-a levels reduced as shellfish density(biomass)increased.
