The landforms of China and the Karst ecological environment in Guizhou;

This paper introduces the fundamental concept, basic functions, mathematical models, analyzing methods and applications of a landforms information system developed by Beijing University taking the geographical information system (GIS) as its basic platform.

Compared with the change of landforms, the existing survey drawing of city and mountain areas renew slowly so we have no exact drawing for reference.

Developing characteristics on the modern tidal-flat geomorphology in Wanggang area, Jiangsu province;

The spatial distribution patterns of digital geomorphology in Xinjiang

Changes of salt accumulation in soil layers with different landforms in Manas River Valley in Xinjiang Region of China;

Formation model and geomorphic evolution of loess hilly landforms;

Study on the Landform of Manas River Valley;

The correlation between topography and near surface structure and its implications to refraction statics in Hangjinqi area.;

Pre-failure topography reconstruction for loess landslide;

According to the topography,land type suitability and human activity,the urban area of Shenyang City was regionalized into four landscape functional regions,i.

The geologic structure, stratum, geomorphy and the features of geologic settlement of quaternary period in Macao District were briefly introduced in the paper and the significance of studying and analyzsing the geological condition of coastal engineering for sea reclamation were pointed out in it.

According to a general theory of conceptual watershed geomorphy concentration model, using the conceptual element of Muskingum reach to simulate the concentration action of each orderingunit channel, a watershed geomorphy concentration model in which the parameters are a flood-wavevelocity and a diffusion coefficient is developed.

According to a general theory of conceptual watershed geomorphy concentration model, using the conceptual element of diffusion analogy reach to simulate the concentration action of each ordering unit channel, this paper developes a diffusion analogy type watershed geomorphy concentration model in which the parameters are flood wave velocity and diffusion coefficient.
