Abstract: |
Logistic model is used to indicate the growth of the model. Taking Yiwu city, Zhejiang as the example, this paper applies the calculation of K value and E value in logistic model to the limited value and the development degree of urban landscape evolution. According to the landscape types data in four stages, fourpoint scheme was used for analyzing the results of K value and E value with logistic model, it can be concluded that the landscape development is the first for traffic landscape (71.10%), the second for the public establishment landscape (65.37%), the third for industrial landscape (63.76%), the next for commerce & service landscape (27.65%), and the last not the least for greenbelt landscape (27.59%). According to the calculated E value of 2020, it indicates that the evolution degree of traffic landscape, industrial landscape, and public establishment landscape are exceed 97%, these are very close to K value. E value of urban residential landscape is 89.23%, which indicates that the development space will be limited. While commerce & service landscape, greenbelt landscape, and professional market landscape have about 30% development space comparatively. The results show that K and E value could reflect completely the evolution trend, development degree and development capacity of urban landscape.
