Shule River project area is located in northwest China\'s Gansu province,Hexi Corridor,which is the largest agricultural crop production base of Gansu province and typically arid and semi-arid areas. There are characteristics such as scarce rainfall,the temporal and spatial distribution inequality,strong evaporation,fragile ecological environment,the limited quantity of surface water. Agriculture,the people\'s living and ecological environment are significantly dependent on the groundwater. Based on the collection and processing of regional hydrological and geological data and the groundwater monitoring data,using the numerical simulation,geostatistics theory and multi-objective evolutionary algorithm,this paper studied the monitoring and evaluation of groundwater resources from the three aspects: groundwater numerical simulation and prediction,groundwater spatial variability and distribution and optimization modeling and sloving of groundwater monitoring network. The main work and research lies:(1) Using Yumen-Tashi basin,Anxi-Dunhuang basin and Huahai basin as study area,this paper used modflow model to simulate groundwater flow of three areas.

The results show that the dynamic change of water resources in the Heihe River Basin is mainly reflected by three aspects, i.e., the formation, utilization and disappearance of runoff respectively, the runoff formation area accounting only for 10% of total area of the Heihe River Basin plays a dominant role in the dynamic change of water resources in the whole basin and affects the capabilities of take-in and send-out, conservation, evapotranspiration and conversion of water resources.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.
