The landslide disaster has become the second largest natural disaster. To analyze the landslide disaster caused by the rainfall, this paper collected and analyzed the data about disaster and rainfall of nearly eight years in Lanzhou, and studied the spatiotemporal coupling early Warning model for the landslide disaster. Then, on the platform of MapGIS IGServer, it utilized the new RIA technology Silverlight and the coupling with Web Service to establish the meteorological Warning system for geological disaster in Lanzhou by the process-oriented mode and in a network with asynchronous response. The test indicates that this model could provide more accurate and timely information for the development of disaster prevention countermeasures. © Sila Science. All Rights Reserved.

Drought is one of the principal pertubations in Poyang Lake Ecological Economic Zone(PLEEZ). It is important to investigate the mechanism of droughts in order to evaluate potential losses of droughts and provide a scientific basis for policymaking. We selected fourteen indicators representing exposure, sensitivity and adaptive capacity to droughts respectively. The weights of the indicators were calculated by analytic hierarchy process. Then using the composite index approach these indicators were combined into a drought vulnerability index of agricultural system by a linear aggregation. Maps of drought vulnerability and its elements in PLEEZ were drawn by applying the software of ArcGIS9.3. The results showed that the drought vulnerability of the agricultural system in PLEEZ were mainly at middle rank. Spatial differentiation of the drought vulnerablity existed that the rank of the drought vulnerability in the northern areas of PLEEZ were higher than that in the south. On the basis of the relationship between the drought vulnerability and exposure, sensitivity and adaptive capability, some suggestions for the drought hazard management in the future were proposed.

ENVISAT ASAR data's ability of penetrating through cloud and rain belt is stronger. It is an important data source to extract water coverage during cloudy rainy weather conditions on the flood reason of Poyang Lake. This paper used ENVISAT ASAR data, monitored the variations of Poyang Lake water area in 2009 by the partition threshold method. Finally get Poyang Lake water coverage's area and spatial distribution. Through the construction of sharing service platform achieve real-time information sharing of Poyang Lake water coverage thematic maps, make users at all levels can obtain real-time, rapid, low cost monitoring information of Poyang Lake, and provide the flood disaster quasi real-time monitoring and warning service, which provide a reliable and important data support for Poyang Lake water allocation, flood and drought disaster reduction, disaster assessment and post-disaster compensation. © 2011 Springer-Verlag.
