Urban Dynamics

In the context of rapid urbanization, it remains unclear how urban landscape patterns shift under different urban dynamics, in particular taking different influencing factors of urban dynamics into consideration. In the present study, three key influencing factors were considered, namely, housing demand, spatial structure, and growth form. On this basis, multiple urban dynamic scenarios were constructed and then calculated using either an autologistic regression–Markov chain–based cellular automata model or an integer programming-based urban green space optimization model. A battery of landscape metrics was employed to characterize and quantitatively assess the landscape pattern changes, among which the redundancy was pre-tested and reduced using principal component analysis. The case study of the Munich region, a fast-growing urban region in southern Germany, demonstrated that the changes of the patch complexity index and the landscape aggregation index were largely similar at sub- and regional scales. Specifically, low housing demand, monocentric and compact growth scenarios showed higher levels of patch complexity but lower levels of landscape aggregation, compared to high housing demand, polycentric and sprawl growth scenarios, respectively. In contrast, the changes in the landscape diversity index under different scenarios showed contrasting trends between different sub-regional zones. The findings of this study provide planners and policymakers with a more in-depth understanding of urban landscape pattern changes under different urban planning strategies and its implications for landscape functions and services.

With the acceleration of the process of building a national-level central city in Wuhan, the landscape pattern of the city has undergone tremendous changes. In this paper, remote images are classified through the neural network classification method, based on texture extraction, and the evolution of landscape patterns was quantitatively analyzed, based on the method of moving windows, landscape metrics and urban density calculation, in order to accurately extract landscape types and perform quantitative analyses. Wuhan City is taken as an example. The surface coverage of Wuhan City from 1989 to 2016 is divided into four types: agricultural landscape clusters, forest landscape clusters, water landscape clusters, and urban landscape clusters. It was concluded that, during the study period, the landscape heterogeneity of the entire area in Wuhan has increased, but the central urban area in Wuhan has decreased. The development of urban areas has compacted inwards but expanded outwards. In addition, the western part of Wuhan City developed better than the eastern part.

The City

The quality of urban environment has increasingly been regarded as an important matter, being analysed from different points of view (quality of life, economic trends, accessibility to major facilities etc.). In this study case, we use Iași Municipality for analysing city-wide relationships betwen anthtropogenic factors (landuse, connectivity, population density, occurence of urban facilities) and natural ones (topographic features transformed into landslide susceptability). The indicators taken into consideration, appended into an factorial analyses are predictors for changing environment in a dynamic context. Connectivity is the most influent factor, having the capability to reshape the structure of density of population or occurence of facilities whence they modify the shape of the entire city. The landscape patterns of Iași city reveal a different image upon landuse of the city, creating an integral display upon the urban area analysed.

The author’s observation on the new urban form of Ankang city grounded on the landscape pattern by analyzing and evaluating the present conditions of land resources, historic cultural attractions, and natural landscape from ecological perspective, finding out the problems in the current construction of urban landscape environment with consideration on local special landscape theme. Besides, the authors emphasized and constructed the landscape patterns at master planning level by layout of city green corridor, preservation of the wetland as the urban corn and improvement of the urban green space system in combination of history, culture and natural environment, urban space and urban spirit, as well as history and future construction.
