The area of no danger, light danger, medium danger, severe danger and extreme severe danger regions respectively are 278 000, 288 000, 217 000, 127 000, 15 000 km^2. Furthermore, the counties in the UYRW are classified into four classes based on the hazards degrees in each county. The number of severe danger, medium danger, light danger and no danger counties respectively are 49, 82, 77 and 105. The assessment results will be provided for the hazards forecasting and mitigation in the UYRW and ongoing regionalization of Main Function Regions in China as data and technique framework.展开更多

According to these comments, UCP valued technologies and tools exces- sively （＂task＂）, and did not pay much attention to methodology （＂discipline＂）. Actually, both ＂task＂ and ＂discipline＂ are geographical wings, especially in the time of ＂big science＂. Enlightenment from UCP and its comments is the strategic direction that should be balanced between ＂task＂ and ＂discipline＂, GS should be a three-dimensional construct of a disciplinary system, methodology, and technologies and tools, and this system should be scientific hu- manism based on scientific spirit and directed by humanism. During the last 60 years, Chi- nese geographers devoted themselves to GS, including practice and theory. Obviously pro- gress and outlook are proposed as interdisciplinary GS, Earth Surface Sciences （ESS） and Geographical Construction （GC）. The disciplinary system of GS is very complex, and is composed of such human knowledge domains as sciences, technologies, engineering, and philosophy. The main mission is to research the open, complex, and macro earth system （not only scientifically, but also humanistically）, and one significant methodology is ＂comprehen- sive integration of qualitative and quantitative means＂ （CIQQM）. At the same time, another changing direction in Chinese geography is Human-Economic Geography （HEG）.展开更多

Together with other branches of information geography, it seeks the balance between universality and particularity of geographical laws by combining methods from neighboring disciplines(such as big data and artificial intelligence) with the special nature of geographical spaces. Meanwhile, at the core position of the geography discipline, GIScience makes geography stronger from two directions: "strengthening the theoretical foundation" and "improving technology and promoting the practical applications".展开更多
