    Abstract: A commercial drone was used to acquire a series of images in an area in the Venezuelan Andes characterized by the deformation of a regional strike-slip fault. The digital model obtained by processing the images has allowed to obtain quantitative measurements of the fault displacement and to test geological concepts related to the structure evolutio...

    Abstract: The evolution of urban functional land is the spatial reflection of urban functional agglomeration and diffusion, it can profoundly reveal the internal characteristics of urban expansion. This paper applies spatial analysis tools of GIS to explore the spatial-temporal evolution characteristics of residential land, industrial land and public service... Show More

    Abstract: We are all dependent on water. We need it every day, in so many ways. We need it to stay healthy; we need it for growing food, for transportation, irrigation and industry. Under the existing trend of climatic change, serious problems will occur accompanying the intensive migratory processes of the population living in the arid regions. The main goa... Show More

    Abstract: An old-field chronosequence in the subalpine region of the Tibetan Plateau were used as a model system to test a hypothesis that forbs drive pathways of successional trajectories in earlier stages of succession and grasses drive the development of vegetation in later successional stages. All old fields were dominated by forbs, which accounted for 6... Show More

    Abstract: The satellite magnetic anomalies are used to calculate the Curie point depth of the Southeast Tibet by spectral analysis method in the study. The relationship between the Curie point depth and the regional faults or heat flow will be discussed. The results show that the Curie point depth of the study area ranges from 15 km to 36 km and the average ... Show More
