With the acceleration of China's modernization, soil erosion caused by illegal activities in production and construction projects is becoming serious. Timely and effective monitoring and supervision is necessary. Traditional monitoring methods have many shortcomings, such as long period, limited precision, limited terrain. So it can't demonstrate the real situation of the project construction area...
Remote sensing is an important technology in the field of drought monitoring. Most traditional methods by remote sensing construct relationship between image features and land real data. Usually the models are complicated and the parameters are difficult to confirm. The surface water directly influence the irrigation and drinking, so monitoring water area changing can reflect drought situation. In...
The drought monitoring by remote sensing technology has advantages than traditional ground monitoring. Up to now, most researches on drought monitoring are focused on constructing the relationship between parameters of remote sensing and land surface. Most current models are complex and indirect, instead, the water area directly reflects drought situation especially in the region where the irrigation...
South-to-North Water Transfer Project is the strategic move to implement the water resource allocation of China. The east line of the project is carrying out which would bring with it a lot of water environmental and ecological problems because of the wide range, long time and complex environment problems facing as well as some uncertainty the environment and ecology themselves have. In this paper,...
In sensor networks concerning about data, data management and representation have become a crucial issue. In this paper, sensor networks deployed to monitor wetland are built with the visualization of their data and topology. The environmental data, such as temperature, humidity, both in atmosphere and soil, illumination intensity and PH around the wetland are sent by the wireless sensor networks...
The Yellow River is well-known for its highest sediment contents of all rivers in the world. Due to the huge sediment to the coast, the Yellow river delta is the youngest land of China, and still in a state of continuous dynamic change. The evolution of the coastline of Yellow River delta is closely related to the environment change of the flow and sediment in the Yellow River estuary. In recent 10...
