Abstract
In temperate continental climate zones with hot summers and significant diurnal temperature differences, the park green space construction is an effective way to increase park visitor comfort and mitigate urban daytime high temperatures. In this experiment, 42 plant configurationss were selected and classified into 12 configuration typesbased on three indicators of the underlying surface, tree species, and canopy density in 6 parks in Yinchuan, Wuzhong and Zhongwei cities of Ningxia, China, in the summer of 2019 and 2020.The air temperature of the sample plots (8:00 ~ 18:00) was measured with a Kestrel NK5500 weather station, and the daily air temperature variation pattern of each typical plant configuration was analyzed, the cooling effect of the 12 configuration types and its controlling factors were revealed based on the air temperature difference (park air temperature—weather station air temperature). There was a significant negative correlation between canopy density and the cooling effect of green lands(P < 0.05,the same below), but the underlying surface and tree species configuration of the green lands could not contributed to the cooling effect. The park green lands with ≥ 40% canopy density had a significant cooling effect compared with hard-paved park areas during the daytime (8:00–18:00). The average daytime temperature of green areas with 40–60% canopy density decreased by about 0.5 °C, and those with > 60% canopy density decreased by 1.1–1.5 °C. In the daytime, the cooling effect of green areas was stable from 8:00 to 12:00 and from 12:00 to 15:00, when the degree of canopy density reached 50% and 40% and above, respectively. And from 15:00 to 18:00, all plant configurations (including grass) had a cooling effect, and the overall cooling effect increased with the process of canopy density.This study provides guidance for the risk management of summer high temperatures and the planning of public green space construction based on cooling effects in cities of continental climate zones.

Description
The journal has an applied focus: it actively promotes the importance of geographical research in real world settings
It is policy-relevant: it seeks both a readership and contributions from practitioners as well as academics
The substantive foundation is spatial analysis: the use of quantitative techniques to identify patterns and processes within geographic environments
The combination of these points, which are fully reflected in the naming of the journal, establishes a unique position in the marketplace.
RationaleA geographical perspective has always been crucial to the understanding of the social and physical organisation of the world around us. The techniques of spatial analysis provide a powerful means for the assembly and interpretation of evidence, and thus to address critical questions about issues such as crime and deprivation, immigration and demographic restructuring, retailing activity and employment change, resource management and environmental improvement. Many of these issues are equally important to academic research as they are to policy makers and Applied Spatial Analysis and Policy aims to close the gap between these two perspectives by providing a forum for discussion of applied research in a range of different contexts
Topical and interdisciplinaryIncreasingly government organisations, administrative agencies and private businesses are requiring research to support their ‘evidence-based’ strategies or policies. Geographical location is critical in much of this work which extends across a wide range of disciplines including demography, actuarial sciences, statistics, public sector planning, business planning, economics, epidemiology, sociology, social policy, health research, environmental management.
FocusApplied Spatial Analysis and Policy will draw on applied research from diverse problem domains, such as transport, policing, education, health, environment and leisure, in different international contexts. The journal will therefore provide insights into the variations in phenomena that exist across space, it will provide evidence for comparative policy analysis between domains and between locations, and stimulate ideas about the translation of spatial analysis methods and techniques across varied policy contexts. It is essential to know how to measure, monitor and understand spatial distributions, many of which have implications for those with responsibility to plan and enhance the society and the environment in which we all exist.
Readership and Editorial BoardAs a journal focused on applications of methods of spatial analysis, Applied Spatial Analysis and Policy will be of interest to scholars and students in a wide range of academic fields, to practitioners in government and administrative agencies and to consultants in private sector organisations. The Editorial Board reflects the international and multidisciplinary nature of the journal.
