Chinese Road Natural Area Based On The Gis-landform And Software System

Along with the rapid development of transportation and computer technology, the traditional highway natural zoning has not been able to reflect the comprehensive and correct relations of the geographical environment and the highway engineering. This topic proposed on this background, with the aid of the natural area and the GIS technology, which produces the system of the highway natural zoning.Based on the concept of Geographic Information System (GIS) and the highway natural zoning,analyzing the insufficiency method of the existing natural zoning. the first portion about the highway landform natural zoning use the ArcGIS spatial analysis function and ArcGIS development language VBA to analyze the various landforms physical features, including the elevation, terrain slope, cutting depth, cutting density, crag soil and vegetation coverage, From this we can obtain landform environment parameter which is the highway engineering difficulties, Simultaneously the author obtains the highway landform natural zoning according to the landform type and the landform shape. The next portion about the geographic information system of the Chinese highway natural zoning, According to demand, detailed analysis of the system structural design, database design, contact surface design, functional design and so on, this system structure uses the union of C/S and B/S, by using the interface to transport the COM objects through the ArcObjects modules, with the VB.Net development language, the author realizes special system's inquiry, browsing, analysis functions and so on..This system make the highway engineering construction use resources effectively, reduces the construction cost, reduced and the control and reduce the bad affects of natural condition to the highway engineering, lengthens the service life and reduce the natural environment changes by the reaction of highway construction to the natural condition. It builds the good foundation for the transportation and the natural environment sustainable development, which has the extremely positive significances.
