青藏高原是世界中低纬度地区最大的冰川区,受气候变暖的影响,青藏高原大部分地区的冰川普遍加速退缩,冰川相关灾害(如冰崩、冰湖溃决等)增多。然而,青藏高原的冰川变化特征在时空尺度上具有高度异质性,尤其是在高原中部,冰川分布相对稀疏,其对气候变化的响应机制有别于其他区域。因此,对青藏高原中部典型冰川开展长时段、多时相的物质平衡和面积变化综合监测研究,对深入了解该区域冰川变化趋势及其对气候变化响应机制等具...
地学院测绘系18级博士生杨莹莹同学论文‘Fractional evergreen forest cover mapping by MODIS time-series FEVC-CV methods at sub-pixel scales’被一区期刊 ISPRS Journal of Photogrammetry and Remote Sensing接收发表,基于中等分辨率遥感时间序列数据实现了大尺...
应用遥感与地理信息系统技术构建基于GIS模型的蓄滞洪区空间数据库,对蓄滞洪区内的基础地理数据进行存储、管理,并对空间数据进行可视化和空间分析等操作;运用RS技术对蓄滞洪区内的土地利用、生态环境变化等情况进行动态监测,建立蓄滞洪区发展指标体系;探求蓄滞洪区的和谐发展模式,为蓄滞洪区的可持续发展提供科学依据。
Considering that the Philippines is archipelagic in nature and is exposed to disasters accentuated by climate change, water resource monitoring and management has been an important concern in the coun...
Atmospheric MTF(Modulation Transfer Function) takes a critical role in restoration of atmospheric blurred RS(Remote Sensing) images. This MTF can be determined by meteorological data. Among the existi...
The climate changes will be much more significant over the next 100 years and may lead to the heavy rainfall event. The heavy rainfall causes the flood hazard in the lowlands and geologic hazard in th...
Ecological security is an important basis of the entire human security system, the cornerstone for human survival. The assessment of ecological security is crucial for making decisions to avoidecologi...
In this research a three-step method was adopted for evacuation planning. At the first step appropriate safe places for evacuation were identified and extracted using RS and image processing technique...
Based upon the in-depth analysis of the remote sensing image sharing demand and the status of the current research on it, this paper points out the existing Web-based sharing-model did not eliminate "...
With the increasing demand for energy sources, a further development hydropower energy resource will be an inevitable choice for China’s resource strategy. The cascade hydropower station construction ...
To extract rules for detecting edges, it is helpful to have some familiarity with different kinds of edges in order to construct a suitable characterization. Typically, researchers have characterized ...
Forest ecosystem is a complex system having interactions with biotic and abiotic components. It includes not only plant and animal communities but also microorganisms, climate, sunlight, water and so...
