In order to certain the landscape pattern and ecological security in Zhangjiagang, the landscape characteristics of urbanization phase and suburbanization phase were analyzed, using remotely sensed imageries between 1991-2006, land use maps and GIS technology, combined with urban-suburban-rural gradient research. Based on the landscape changing and its driving force analysis, the regional Cultivated...
Morphological visualization is one of the key technologies for constructing virtual plant. The three-dimensional organ maps of rice are constructed by OpenGL, combining the characteristics of short development cycle and easy operation and maintenance of C#, and the design methods of object-oriented are used to construct the maps. Each rice organ is abstracted into different classes by using C#, and...
In order to fit socialization and marketization of peasants' production and life, countryside comprehensive service system comes into being gradually. Information service platform of new countryside includes five function modules, such as “developed production”, “richness life”, “civilized fashion”, “tidy village” and “democratic management”. To complete this project, the underlying database was well...
In order to solve the problem of nitrogen over-use in high yield direct seeding rice after cultivating wheat, the research explored different nitro-saving cultivation method from 2008 to 2009, by increasing the rice planting density to enhance yield on wheat stubble. This study set up a test of different direct seeding density in 2 years continuously with 150 kg nitrogen application dose per hectare...
In this paper, a five-parameter statistic model of spectral Bidirectional Reflectance Distribution Function (BRDF), which contains both of specular and diffuse reflection factors, is introduced for space target surface material. The optimal five parameters of the model at different wavelength are independently retrieved by using simulated annealing algorithm (SAA). An absolute measurement method of...
