The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.

摘 要：2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查，结果表明，投礁后礁区海域游泳生物的资源密度明显比投礁前高，增加了25.63倍；礁区海域各类资源种类均比投礁前丰富，总种数由投礁前的23种增加至41种，比投礁前增加了0.78倍，其中，蟹类种数增加最多，增加了1.75倍；在本底调查中没有出现的经济种类龙头鱼 Harpodon nehereus 和红星梭子蟹 Portunus sanguinolentus 在跟踪调查中已成为主要优势种；Shannon-Wienver多样性指数在礁区和对比区均比投礁前有所增加。

At present the mechanism of endangered species mostly confined to the morphology point of view, few physiological point of view of ecology, the lotus leaf fern Adiantum growth conditions of the study also stay in more qualitative analysis, there are few quantitative analysis of its optimum growth environment , The experimental use of morphological and physiological ecology of the idea and will use the components of the research methods, to be a long time to further explore their own independent development of plant taxonomy, morphology, physiology, ecology and other subjects the intrinsic link between , With a view to a new high on the survival of endangered species, adaptation and evolutionary mechanism.

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。
