地理科学专业人才培养方案与课程体系比较研究

文章选取从北到南4所高校为样本,对各校地理科学专业人才培养目标、课程设置、毕业总学分与修业年限要求等方面进行比较研究。发现学校发展的历史背景及办学积累、区域社会文化环境、师资资源等几个方面会影响地理科学专业高校课程体系设置。我国高校地理科学专业在人才培养方案与课程体系建设上应该更加重视公共选修课程体系建设、加大专业选修课程比例、加强突出课程特色的区域地理课程构建、重视小班研讨课程。

Impacts of Land Use and Cover Change on Land Surface Temperature in the Zhujiang Delta

Remote sensing and geographic information systems (GIS) technologies were used to detect land use/cover changes (LUCC) and to assess their impacts on land surface temperature (LST) in the Zhujiang Delta. Multi-temporal Landsat TM and Landsat ETM+ data were employed to identify patterns of LUCC as well as to quantify urban expansion and the associated decrease of vegetation cover. The thermal infrared bands of the data were used to retrieve LST. The results revealed a strong and uneven urban growth,which caused LST to raise 4.56℃in the newly urbanized part of the study area. Overall, remote sensing and GIS technologies were effective approaches for monitoring and analyzing urban growth patterns and evaluating their impacts on LST.
