查询词典 value of assessment

Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

Four items of water quality has been collected in field surveys, including PH value, dissolve oxygen, electric conductivity level and turbidity level. Furthermore, 19 species of freshwater fish have been found, of which 10 species are local strains, 4 species are foreign strains, and 1 species is a hybrid strain. The results of calculating and analyzing the water quality index and Index of Biotic Integrity indicate that WQI is estimated from excellent to fair, while IBI is estimated from fair to poor. It has been illustrated that two indexes show different assessment results. Of those WQI index is more reliable than the IBI. IBI index need further modification for the use of water quality assessment in the Tou-Bien-Ken Creek.

After analyzing the impacting factors of natural vulnerability along the Pearl River mouth, the paper divides the coastline of approximately 412km into 25 15-minute gird cells. For assessment purposes, the six variables including geography, relative sea-level change, average tide range, regional slope, shoreline erosion or accretion rates and tropic cyclone impacting frequency are selected as assessed variables. Once each section of coastline is assigned a risk value for each specific data variable, the costal vulnerability index can be useto calculate the natural vulnerability of the areas along the Pearl River mouth. After that, the paper develops a database for assessment of coastal vulnerability to sea-level rises and protracts a 1:2,000,000 vectors CVI map of the coastlines along the Pearl River mouth.
