Spatial point pattern analysis of human settlements and geographical associations in eastern coastal China - a case study.

Zhang Z, Xiao R, Shortridge A, Wu J - Int J Environ Res Public Health (2014)

Bottom Line: This study demonstrated a new approach to analyzing the spatial patterns of human settlements from a wide geographical prospective.We argue that the spatial point patterns of settlements, in addition to the characteristics of human settlements, such as area, density and shape, should be taken into consideration in the future, and land planners and decision makers should pay more attention to city planning and management.Conceptual and methodological bridges linking settlement patterns to regional and site-specific geographical characteristics will be a key to human settlement studies and planning.

ABSTRACT
Understanding the spatial point pattern of human settlements and their geographical associations are important for understanding the drivers of land use and land cover change and the relationship between environmental and ecological processes on one hand and cultures and lifestyles on the other. In this study, a Geographic Information System (GIS) approach, Ripley's K function and Monte Carlo simulation were used to investigate human settlement point patterns. Remotely sensed tools and regression models were employed to identify the effects of geographical determinants on settlement locations in the Wen-Tai region of eastern coastal China. Results indicated that human settlements displayed regular-random-cluster patterns from small to big scale. Most settlements located on the coastal plain presented either regular or random patterns, while those in hilly areas exhibited a clustered pattern. Moreover, clustered settlements were preferentially located at higher elevations with steeper slopes and south facing aspects than random or regular settlements. Regression showed that influences of topographic factors (elevation, slope and aspect) on settlement locations were stronger across hilly regions. This study demonstrated a new approach to analyzing the spatial patterns of human settlements from a wide geographical prospective. We argue that the spatial point patterns of settlements, in addition to the characteristics of human settlements, such as area, density and shape, should be taken into consideration in the future, and land planners and decision makers should pay more attention to city planning and management. Conceptual and methodological bridges linking settlement patterns to regional and site-specific geographical characteristics will be a key to human settlement studies and planning.

ijerph-11-02818-f001: Location of the Wen-Tai region, Zhejiang Province, China.

Mentions: The Wen-Tai region is located in southeastern coastal China (Figure 1) within the province of Zhejiang, with a spatial extent of 27°03′–29°08′N and 119°37′–121°26′E. It contains 16 counties, covers 21,667 km2, and had a population of about 13.7 million in 2008 [39]. This region has a subtropical monsoon climate with moderate temperatures, abundant precipitation, and distinct seasons. The average annual temperature in this region is 18.8 °C, and annual rainfall is 1,922 mm. The topography of this region is rugged: about 75% of the total area is mountainous. The eastern coastal region plain is lower and more level, while the western regions are comprised of valleys surrounded by steep mountains, typically covered in dense forests. Like other parts of eastern coastal China, the Wen-Tai region has recently witnessed explosive socio-economic development. Over the past twenty years the population in Wen-Tai increased by 16%, and GDP increased by 3,475% [39]. A unique aspect of Wen-Tai is its distinctive economic development patterns. From the 1980s, the Chinese government implemented a series of policies such as “the market transition” to promote an export-oriented economy in eastern coastal cities [40]. Such policies, coupled with the terrestrial inaccessibility of Wen-tai, resulted in the “Wenzhou model”, in which local private business developed rapidly, facilitated by provincial and especially municipal government [41]. Wen-Tai relies heavily on its own resources, and local governance, and is therefore less affected by national trends and policies than other regions in coastal China. As a consequence, settlement locations within this region are mainly affected by local and geographical factors. Wen-Tai provides a useful case study for the analysis of geographical associations with settlement patterns.
