We used the Moran’s I to reveal the spatial agglomeration pattern of the China’s agricultural drought disaster. Some of the important conclusions derived are given below: We analyzed the spatial-temporal evolution of China’s agricultural drought disaster based on the Moran’s I at the national...
The spatial correlation pattern of economic resilience is an important proposition for China’s sustainable economic development. This paper measures the economic resilience of 31 provinces in China from 2012 to 2020, and explores the spatial correlation
Table 1. Definition of place-based values used in PPGIS mapping. Adapted from Brown and Reed (2000) to the Norwegian context. Place-based valuesDescription Biological diversity Areas are important because they provide a variety of plants, wildlife and habitat Clean water/air Areas are important be...
Fuzzy pattern recognition 1 Fuzzy risk modeling 1 Gray relational analysis 1 Total 214 Next, we analyzed different methods used in the 145 application using probability theory. As shown in Table 2, general probability theory, Bayesian probability, and probability map are most commonly used in GIS....
However, the increase in human activities, intensity, and disturbance inevitably brought a series of ecological and environmental problems, so the gradually increasing social and human factors of coercion should be addressed. Figure 6. Spatial pattern of ecological functions in the Yangtze River Delta ...
The spatial pattern of these number sequences, called contextual numbers, summarizes the variations of geographic locations in high-dimensional space in a single contextual map (Figure 8b). Like other dimensionality reduction methods in Section 4.1.3, such a feature (with the advantage of being a...
Such fixes delimit the main spatial and temporal31The following definition differs from that offered by D. Harvey,The Limits to Capital,Oxford: Blackwell Publishing, 1982; for an explanation, see B. Jessop,“Spatial Fixes, TemporalFixes, and Spatio-Temporal Fixes”, in: N. Castree and D. ...
A general definition of support is “the largest time interval [T], area [L2] or volume [L3] for which the property of interest is considered homogeneous” [57]. The spatial resolution of an observation can be equated with its spatial support, and its temporal resolution with its temporal ...
Taking this theory of economic geography one step further is Christaller's central place theory of 1933. Christaller demon- strated how, under certain conditions, a hierarchy of places would surface in a hexagonal pattern shaped by market ar- eas. Apparent in its name, central place theory is...
In order to explore the clustering pattern of OPPs visually in local areas, a local spatial association test was carried out. As reported in the LISA distribution maps in Fig. 4, the OPPs in adjacent provinces had clear local correlation. Here, the significant LISA indices are mainly distribute...
