| According to the theory of digital city and digital earth, the total frame, contents,method and key technique to construct digital Yangling have been discussed and thedatabase models of spatial basic information system have been supposed. Assisted by modern survey instruments of GPS and Total Station, mapGIS-basedspatial basic information system of Yangling has been constructed under the support ofMap2002. On this basis, development trend of landscape and gardening green land andtraffic roads status of Yangling have been analyzed. The main results of this study areshown as following: 1. Preliminary spatial basic information systems including landscape informationsystem, gardening information system and traffic ways information system of Yanglinghave been constructed in this paper. Firstly, through constructing land use and landscapeinformation systems of Litai village of Yangling in 1996 and 2002 respectively, spatialdatabase of landuse, traffic road web, district boundary, topography and other relevantproperty and map database have been designed. Secondly, through constructing gardeninggreen land information system of south campus of northwest sci-tech university ofagriculture and forestry, spatial database of gardening green land, boulevard, roadside trees,free growing trees and relevant property and map database have been designed. Thirdly,through constructing traffic road information system of Yangling, spatial database of roads,topography, traffic ways, station and relevant property have been designed. All thesubsystems have functions of data adopting/updating, information inquiring, spatialanalysis and monographic maps outputting etc. They have also functions of enlarge/reduce,storied display, map/document integration and so on. 2. Development and Status of Land use of Litai village, gardening green land andurbantrafficinYangling have been analyzed. Main results include: (1) MapGIS-based analysis on the landscape development acquaints us with theamount, distribution and utilization of land in Litai village of Yangling. It shows thatcropland had a great decrement during the period 1996～2002, which amounted to30.8458 hm2 and took a percentage of 17% of the total land and decreasing rate of 2.8%annually. Other land types except for rural inhabited land had increased in area differently,in particular of enterprises/factories and traffic ways occupied lands. According to theanalysis, enterprises/factories occupied land had increased 16.2707 hm2, which took 9.02%of the total land. Traffic ways occupied land had increased 6.526 hm2 , 3.62% of the totalland. Whereas, rural inhabited land had decreased during this period, which was mainlydue to the decrement of mausoleums occupied land. In addition, the degree of landscapefragmentation was increased during this period of 6 years. Except for rural inhabited land,other land types had increased in amount of patches but decreased in average area. According to dimension analysis, the dimension from 1996 to 2002 had conservedstable relatively, which was among 1.02～1.44. This result shows that the land patches hadtaken simple geometric shapes in Litai village. Besides, the diversity, fragmentation andsuperiority of landscape in Litai had increased. This means that the landscape structure inLitai is developing in the direction of more and more different. (2) Assisted by modern survey instruments of GPS and Total Station, the gardeninggreen land status of Yangling has been analyzed. Through analysis, it shows that the area ofgardening in Yangling was 142.02 hm2 in total and it took 27.73 % of the whole land. Thiswas a little higher than the average level of whole China (25.53%), but much lower thanthe average of 12 gardening cities in China (36.07%). The average gardening land percapita in Yangling was 21.1 m2, which mostly belonged to the institutions and very few tothe public. It also showed that, in respect of function, the gardening in Yangling took the...
