Abstract:

All land use types in the city are affected by human, but the impact on each type varied enormously, hence vertically forming a certain distribution model. In a flat country, distance is the most important factor that interferences the distribution of land use; and basing on this assumption, Von Thünen and Burgess introduced their famous concentric models. However, the absolute flat country is inexistent, so how does the elevation affect the distribution of urban land use? Would it establish its own unique land use model of distribution in vertical orientation? In this paper, a case study was conducted in Guangzhou City by comparing land use vertical distribution pattern in 1990, 1995, 2000, 2005 and 2009 using remote sensing image interpretation and DEM data. The results showed that: 1) Various types of land use showed different characteristics of distribution changing with elevation. Some types of land use are mainly concentrated in a range of elevation, while other types of land use are relatively scattered. 2) From low elevation to high, the most dominant types of land use vary from farmland, water, urban land, orchard, to woodland in 2009. With the raise of elevation, the advantage of the most dominant type decreases first and then increases quickly. 3)From 1990 to 2009, the overall trend of the magnitude of land use change in vertical orientation are similar: the intensity of land use change decreases with the raise of elevation; and in the progress of land use change, the primary changes of land use are the spread of urban land and orchard and the retreat of farmland and woodland between 1 m to 90 m. 4) Based on the definite landforms and stage of economic development, the corresponding vertical land use hierarchical models of land use will form. From low elevation to high, the vertical land use hierarchical model in Guangzhou is composed of the layers of vertical land use, i.e., mixed layer of farmland, fishpond and shoaly land; mixed layer of water and farmland; mixed layer of urban and farmland; mixed layer of orchard, farmland and agricultural settlements; mixed layer of orchard, woodland and farmland; mixed layer of orchard and woodland; and woodland layer. 5) We discussed the vertical hierarchical model of land use in natural landscape period, agriculture landscape period, rapid-urbanization period, post-urbanization period and complete-urbanization period. And the theory of succession of community in ecology can well explain the evolvement of vertical hierarchical model of urban land use.

Key words: urban land use, vertical hierarchical model, Guangzhou
