Construction and implementation of RS integrated application information system of China''s coastal zone and offshore

The coastal zone and offshore are clearly of major economic and social importance,in thesame time it causes a series of problems of resources and ecosystem too.The research on and development of integrated application techniques for remote sensing provide not only a microcosmic and dynamic and synchronous technical means to the monitor,but also an integrated technical scheme to harmonically solve the ecological environment problem.The system is designed to focus on the application techniques of multi-sources remote sensing data.By developing remote sensing information extraction module,integrated user platform,and application module objected to the real ocean procedure for China''s coastal zone and offshore,the information system consists of the management of prodigious amount of data,display,analysis,simulation and output will be constructed and implemented.The final objective is to transform the research on ocean remote sensing into application.     

Dynamics of Sea Ice and Spectrum of Ice Force

Spectrum and self-excite characters are the two significant characters of the dynamics of sea ice. The spectrum character of sea ice is mainly shown by the spectrum of ice force. The spectrum character of the sea ice is its intrinsic attributes. When the spectrum of ice force from the dynamic response of ice and structure interaction are evaluated, the effect of dynamic character of the structure must be eliminated. In this paper, the ice force spectrum at Bohai Bay and Liaodong Bay is evaluated from the displacement and strain responses of a single degree and a multi-degree freedom structure. The evaluated ice force spectrum can be used to define the spectrum character of ice in the analysis of ice induced vibration.

Observations and Estimations of Directional Spectrum of Sea Waves

The directional spectrum is one of the basic characteristics of sea waves. The observations of directional spectrum of sea waves were successfully conducted at platform Bohai 8 during 1991 and 1992 using a wave gage array for the first time in China. Based on the field data, the directional spectrum which depends on the wave growth is given in this paper. Before observations, the effects of the type of gage array, the distance between the gages and the platform itself on the measured results and the precision of some methods for estimating the directional spectrum were investigated and compared with the methods of numerical simulations and model tests of multi-direcitonal irregular waves. This ensures the quality of the observations and estimations of the directional spectrum.

Construction and implementation of multisource spatial data management system of China''s coastal zone and offshore

To meet the increasing demand of national spatial database infrastructure construction and application, a concept model of China‘ s coastal zone scientific data platform is established based on the information feature analysis of a compound dataset, consisting of remote sensing data and conventional data. Based on this concept model, the detailed logical database structure and the storage strategy of remote sensing data and their metadata using ArcSDE are designed. The complicated technology of multisources data combination in this research is crucial to the future coastal zone and offshore database construction and practical running, which will provide intelligent information analysis and technological service for coastal zone and offshore investigation, research, development and management.     

Detection and assessment of cloud cover and precipitation parameters using data of scanning radiometers of polar–orbiting and geostationary meteorological satellites

Two multispectral threshold techniques have been developed and tested for the automatic classification of AVHRR/NOAA and SEVIRI/Meteosat-10 data. They provide day-and-night detection and the assessment of cloud-cover parameters, as well as the discrimination of precipitation zones and severe weather phenomena. The validation of output information products, which has been performed with ground-based conventional meteorological observations and radar data, as well as with independent satellite-based estimates of cloud cover and precipitation parameters, confirms the feasibility of developed techniques and reasonable accuracy of output products. Therefore, the technique is concurrent to those implemented in current foreign satellite centers.     

Second sea-entering approach of Changjiang River: Tonglü Canal-planning of control dimensions, analysis of erosion and siltation and selection of outlet

Assume that the Tonglu Canal would be widened and deepened in which a water lock is constructed at the river side, and made open to the sea side.The canal''s planned control dimensions are determined, and the erosion and siltation characteristics along the river (totally 81.8 km) are analyzed by the numerical calculation of one-dimensional unsteady flow and the relative standards.According to the data of the evolution, hydrology and sediment in the Xiaomiaohong Waterway, it is found reasonable to select the channel near the Xingang Gate as the second sea-entering approach.This paper is helpful in planning and designing the approach.
