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。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
