Monitoring Water Resource in Taiyuan, China Using HJ-1B Imagery

Abstract

Remote sensing technology can be used to quickly extract macro information of the study area, and its advantages in monitoring water resources have become increasingly evident. In this study, Fenhe 2nd reservoir and Jinyang Lake in Taiyuan，Shanxi Province were examined using the remote sensing data obtained from HJ-1B on May 6, 2010. Water area of Fenhe 2nd reservoir was extracted using NDWI and improved segmentation threshold. The distribution of eutrophication and phytoplankton in Jinyang Lake were analyzed using NDPI and a profile map of phytoplankton was produced. Results show that spatial and spectral resolution of HJ-1B can meet the requirements of water resources monitoring well, which are conducive for further promotion and application of HJ-1B remote sensing data.

Development Status and Trends of Mass Finishing Processes

“…The solution consists of a liquid or dry powder that is diluted in water and primarily acts to reduce friction between media, flush soil and debris from the bowl, and to form a rust inhibiting layer on finished part surfaces [6]. Development of media and compound primarily depends on experiments, effects of surface roughness and material removal with different media parameters have been done to practical application [2,46,[49][50]. Some compounds are based on organic substances, which are almost completely biodegradable [39].…”

Leveraging a New Base Belief Function for Conflict Data Management and Decision Support

“…Despite the wide use of the D-S theory, scholars observed that classical D-S theory unable to produce reasonable outcome in case of paradoxes (because of complication of realistic environment and probable conflicts of sources of evidence) [32]. Therefore DCR is improved previously before its application in this paper.…”
