| 英文简介 | Taking special water-heat conditions, soil types and physiological ecology nature of plants as the background, using multi-disciplinary theories of geology,hydrogeology, geochemistry, plant physiological ecology and environmental biochemistry and means of multi-technology in desert, Xinjiang, this program studies the formation mechanism of the phytochemical anomalies in metal deposits, establishes the prospecting depth prediction model and selects the prospecting effective indicator plants. The study highlights the four basic issues of distribution, migration-transformation, behavior and migration power of elements, and a core issue of migration-transformation of elements in the matrix-plant system. Among these issues, it is focused on some key technologies, such as the source (depth) of elements in phytochemical anomaly, soil-root interface processes and selection of prospecting effective indicator plants, etc. In theory, the study will profoundly analyze occurrence, causes, conditions, processes and mechanisms of the phytochemical anomalies in special desert landscape. And in practice, it will solve the selection of prospecting effective indicator plant, mineral surveys, delineation of prospecting target and deep exploration using plant media in plants geochemical exploration work in desert. Furthermore, the study achievements will not only have important cutting-edge meaning for the development of plants geochemical exploration in desert areas, but also play an important role in mineral surveys and forecasting of buried deposits for northwest China. |
