Abstract
During recent 30 years, the international hot spots of Geomorphology have been focusing landform evolution histories based upon sedimentation, fluvial landforms and disaster occurrences due to sediments transportation and land surface erosion, landform evolution mechanism based upon modeling simulations. The main achievements of Geomorphology in China include long time scale landform evolution under tectonic and sedimentary controls; engineering landform studies relating with reservoirs, ports and soil and water conservations; past climatic changes based upon sediments’ proxies; loess, karst and other types of landform with China regional features; and landform evolution mechanisms by modeling simulations. In the future, the basic theories, crossing and anastomosing, model simulations are required to be paid more attentions. Keywords
Geomorphology development
A total of 38,092 SCI/SSCI-indexed articles are analyzed in the research field of geomorphology. Articles were identified from 39 international journals from 2000 to 2014. The number of journals that have published more than 15 of the relevant articles is 39 (Appendix N). The search query is as follows: “geomorphology” OR “landform*” OR “weathering” OR “slope” OR “landslide” OR “debris flow” OR “sediment*” OR “deposit*” OR “fluvial” OR “river” OR “glacier*” OR “periglacial” OR “permafrost” OR “karst” OR “loess” OR “coast” OR “delta” OR “tectonic” OR “desert*”.

Overview Development of Research Questions
Geomorphology, the scientific study of the origin and evolution of land surface processes and morphology, seeks to understand the migration of materials and energy transforming/dissipating processes at the interfaces of the

atmosphere, lithosphere and hydrosphere. Geomorphology is an important branch of physical geography that takes the land surface of the earth as the object of research. The first theory of geomorphology was arguably devised by the Chinese scientist and statesman Shen Kuo (1031– 1095 AD). He observed marine fossil shells in a geological stratum of mountain hundreds of miles from the Pacific Ocean. Noticing bivalve shells running in a horizontal span along the cut section of a cliff side, he theorized that the cliff was once the pre-historic location of a sea shore that had shifted hundreds of miles over the centuries. He theorized that the land had been reshaped and formed by soil erosion of the mountains and by deposition of silt, after observing strange natural erosions of the Taihang Mountains and the Yandang Mountain near Wenzhou (Sivin 1995; Needham 1959). In the late 19th century, F. Richthofen systematized knowledge of land surface structure and landform genesis and attempted to construct a classification for landforms. In the books River Evolution Cycle and Geomorphic Cycle, American scientist W.M. Davis proposed some theories, in
