Research On The Application Of 3S Technology In Managing The Pasture Of The Grass

At present, the management of the grassland is at the basic level, most working management still remain at craft stage, lack of the basic data to update, at the same time, the resource of meadow datas are in disorder, the majority use the paper files, and it is inconvenient and inefficiency to upgraded the data. So it is one practical work of value better to utilize materials to serve for new development of pastoral area . In view of this, this paper regards Abaga Banner as studies area, compate three technology of GPS (the technology of satellite location), RS (satellite remote sensing image technology), and GIS (geographical information system) to among the same system, set up the system to manage the information of the grass and pasture in banner and county level, through visual interface to monitor meadow resource and swift the result newly in time for a long time, and offer support for every decision of the administrative department.The information management system of pasture and grass of Abaga Banner based on 3S has carried on the beneficial attempt in some aspects, and apply to animal husbandry's management of grass in Abaga Banner specifically. The application of 3S includes specifically: There is the function of GPS (1) to gather the information of herd; (2) make a reservation to survey yield of the grass; (3) to correct the Image of remote sensing; (4) make a reservation in the pasture and grass to delimit coordinates; (5) makes a reservation of 110 grassland; There is the function of RS (1)to obtain data of land utilizing and desertification; (2)to obtain the vegetation index; (3) to estimate the grass yield of remote sensing.The main function of the system to manage the information of the grass and pasture that integrate 3S technology included (1) to manage user's; (2)to operate the function in map; (3) to manage the function of map layers; (4) to maintain data safe; (5)to manage and inquire the data; (6)to statistic the data; (7)to put the thematic picture; (8)to imbed Google Earth.When the system put into operation, make the change of the quality of grass and pasture of the whole banner, the level of management has attain a new height, and made certain economic benefits and social benefits.
