| 1 | Groundwater System Division and Description of Asia显示文摘Based on landform, climate, river system, geological structure and hydrogeological structure and from the perspective of systematology, the groundwater system of Asia can be divided into 36 secondary groundwater systems under 11 primary ones by the intercontinental scale. This forms part of the work of the groundwater series map of Asia, which is compiled according to groundwater system division and evaluation of the total amount and types of aquifer, reflecting the large-scale features of groundwater resources in Asia. Systematic profiling of groundwater in this way provides a scientific basis for groundwater exploitation planning and management in Asia, and avoiding disputes over groundwater resources and the environment among Asian countries. | ZHANG Fawang YI Qing CHENG Yanpei YUE Chen DONG Hua | 2016 | Acta Geologica Sinica(English Edition)2016，90，4： | 1 |
| 2 | Study on Ecological Environment and Sustainable Land Use Based on Satellite Remote Sensing显示文摘GIS and RS techniques have been applied to interpret satellite data in 1992, 2000 and 2010. Further, the ecological environment factors of these three periods and the data for various types of land use have been obtained. LUDI in the Amur River Basin from 1992 to 2010 has been quantitatively analyzed by using the land use dynamic(LUDI) model and of land use transfer matrix model. The results indicated that from 1992 to 2010 the LUDI of land desertification is greatest, and is the most dramatic change. The comprehensive land use dynamic in the study area is 15.25, hence the land type is characterized by rapid change. In addition the area of woodland and farmland continues to increase, which has been mainly transformed from the mixture of forestland and grassland, marsh and wetland, this is an outcome of the production of shelter-forest plantation in North China, Northeast China and Northwest China. In the ten years period of the study, the area of desertified land has increased, changing mainly from a mixture of woodland and grassland. This study can rovide data for eco-geological environment management. | Jiankang Zhang Yanpei Cheng Hua Dong Qingshi Guo Kun Liu Fawang Zhang | 2013 | Journal of Groundwater Science and Engineering2013，1，1： | 1 |
| 3 | Analysis of Water Resource Demands:Based on the Hydrological Unit显示文摘It is important to take into account land use when considering water resource demands.The Hydrological unit is defined as the assimilation of land use and soil properties into a lumped element,spatially separate area which exhibits a typical hydrological reaction.Using physically based equations,water balance can be calculated and compared for different hydrological units and thus water resources can be assessed.The Huanghua City in Hebei province is taken as an example to analyze the hydrological elements of water resources supply and demand for different land use types.Huanghua City is located in the alluvial plains,which is flat,and geologically uniform.The altitude is generally in 2.5-5 m above sea level.The geomorphology consists of an ancient river course,depressions,shallow depressions,ancient shell dikes and lagoons,typical characteristics of a coastal plain. | Cheng Yanpei Ma Renhui | 2013 | Journal of Groundwater Science and Engineering2013，1，2： | 0 |
