| Agricultural tour park roads are important component of agricultural tour park. Their function is to connect the various park tourist attractions, service facilities. They play the important role of organizing transportation, guiding tours and forming landscape.Combined with the specific circumstances of Wolong Villa, the paper has made a unified planning of the road system. Under the premise of striving to reduce the impact on the environment and destruction of the road construction and road itself, it attempted to build a road system of rational layout, beautiful scenery and perfect function, making its ecological benefit and economical benefit and social benefit harmonious. The main research contents are as follows:(1)Data acquisition and sorting based on the situ investigation: First, Arcgis9.2 was to use to get match and digital map. Then the 3D analysis module transformed the key data of contour lines, elevation points and GPS measurements points into TIN vector data, and made terrain analysis. This method could show the topography intuitive, and do a good job for the subsequent distribution of the slope analysis data base to.(2)The main factors analysis of villa road planning: natural geographical conditions, tourism resource distribution, functional partition, ecological protection requirement, tourist psychology, traffic network.(3)Overall planning is made in five aspects of the road, road layout , road classification, the technical indexes and road location. The technical indexes include the width of the road at all levels, linear, slope, superelevation, crossing etc. Road location are as follows: arcgis was used the to slope analysis, and the importance of attractions was calculated, then in combination with other elements proposals was put forward, through comparisons, the final plan was draw.(4)Based on the overall planning , the layout, width, alignment, pavement and other planning of the main pathway ,the minor pathway and the alley were planed.(5)The road ancillary facilities planning includes road marking, roadside barrier, parking, rest facilities and channel planning. Road marking planning aimed at the marking material, quantity, content and distribution. From the standpoint of safety, environmental protection, economy, durable, the guardrail of the main and minor plan pathway were planning. Parking planning based on the ecological protection and tourists convenient. Seat planning research includes material, layout and design key.(6)The entrance area, the main pathway, the minor pathway, alley and parking respectively plant landscape was planned. According to the local climate, soil, vegetation and other natural conditions and following principles of "mainly of native plants, appropriate introducing varieties","respect species mutual generation and restriction"," economy" and "people-oriented", roadside plants were selected, and their configuration were explored.
