The main reasons caused theses problems are as follows: beyond marine carrying capacity and environment capability by predatory and extensive manners, over-exploitation of bioresources resulted in the disturbance of marine ecosystem and the obstruction of matter and energy circulation. Marine environment pollution and unreasonable oceanographic engineering caused serious damage of marine entironments, weakness of marine eco-functions, and degradation of marine ecosystems. The population explosion as well as the trend of population towards coast inflicted tremendous pressure on marine resources and environment. The weakness of marine laws system and the infirmness of macroscopical control by government policies relulted in unreasonable utilization, inefficient management, and insufficient protection of marine bioresources.

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.
