【作业】第一章 生态学导论 生态学导论

1、 问题:根据我国东海优势浮游植物种群季节性演替的特征，回答为什么会出现这样的演替现象？演替可能与哪些环境或生物因素有关。
评分规则: 【 我国浮游植物的演替特征是春季（4月左右）硅藻（Skeletonema，骨条藻）是优势种群，能够快速的利用上升流带来的营养物质（10分），在春季适宜的温度下，大量增长繁殖，当营养消耗完时，种群快速消亡（硅藻是典型的r-选择生物，10分）。随后甲藻（凯伦藻和原甲藻）占据优势，利用被释放出的营养物质（10分），且由于甲藻的营养方式多样（光合和异养），具有较稳定的生存方式（是K-选择生物，10分），在6-9月长期占据优势。待温度降低或环境条件改变巨大时，生物量降低（10分）。因此，演替可能相关的环境因素包括温度（5分）、光照（5分）、降水（5分）、盐度（5分）、营养物质（5分）、水动力（5分）等；生物因素包括：主要当地优势种群（5分）、摄食关系（5分）、共生关系（5分）、竞争关系（5分）等。

【作业】第二章 海洋生态环境和主要生物生态类群 海洋生态环境和主要生物生态类群

1、 问题:请查阅文献，简述海洋中哪些海域的海洋环境最稳定，哪些海域的海洋生物资源最丰富，并说明原因。
评分规则: 【 海洋的底层海域。
海洋的洋流流动相对缓慢，温跃层出现在中层，而底层的环境平稳而单一。
大陆架海域生物多样性最高。
食物和阳光充足，营养丰富，食物链完善，生物资源高
