The Strategic Significance of Bilingual Teaching in Higher Education Reform and Development in China

Chinese higher education is facing a serious crisis. Bilingual Education plays an important role in Chinese Higher Education Reform. This paper expound the background and essence of bilingual teaching and learning, then discusses the purposes of strategic objectives about the bilingual teaching in Chinese higher education, namely: cure ills of higher education and the promotion of higher education development; make China into the world, let the world understand China; the world personnel training, and promoting world harmony and progress. This paper suggests China should strive to develop bilingual teaching, and make higher education reform and development in the strategic core.

Monitoring and analysis of chlorophyll a concentrations variation information in Dongping lake based on HJ-A/B image

It is significant for its water pollution control and estimation of wet land biomass to fast acquire space-time variation information of Dongping lake. This paper mainly researches the relative technologies of monitoring information on the variation of chlorophyll a concentrations using HJ-1A/1B image, such as, massive data auto- filter, image automatic preprocessing, chlorophyll a concentrations variable information monitoring etc. A processing flow of monitoring variation information of chlorophyll a concentrations, which applies to HJ image, is introduced. From the surveying result in 2009, using this processing flow could expeditiously discover the spatial-temporal variation regularity of chlorophyll a concentrations. The monitoring results could provide reliable data for the system of water quality pre-warning and estimating wetland biomass in Dongping lake.
