Influence of Bioclimatic Variables on Distribution of Public Parks in Nakhon Ratchasima City Municipality of Thailand

摘要

Public parks are believed to be affected to climatic data worldwide, and thus may serve as important indicators of climate change. This study aimed to examine influence of bioclimatic variables on the spatial distribution of 14 public parks in Nakhon Ratchasima (NK) City Municipality of Thailand. Bioclimatic variables were analyzed by BIOCLIM concept that was produced from two spatial climatic factors: rainfall and temperature. Herein, both climatic data were taken from Thai Meteorological Department (TMD) on 30-year period (1981-2010) that was prepared in excel and then was processed by Kriging method. Moreover, the produced-bioclimatic variables from BIOCLIM were selected by 2 the integrated approaches: (1) relating to Thai season and (2) correlation analysis, before some selected bioclimatic variables were used for studying relationship between bioclimatic variables and 14 public parks using GIS technique. As a result, 10 of 19 selected-bioclimatic variables for 14 public parks based on average in NK City Municipality that included: 6 bioclimatic temperatures: mean annually temperature (BIO1) between 27.0098 - 27.0320 °C; mean diurnal range (BIO2) between 10.3571 - 10.3615 °C; temperature seasonality (BIO4) between 2.11028 - 2.11962 °C; annually maximum temperature (BIO5) between 29.6681 - 29.6822 °C; annually minimum temperature (BIO6) between 23.1376 -23.1777 °C; annually temperature range (BIO7) between 6.49168 - 6.5208 °C, and 4 bioclimatic precipitations: mean annually precipitation (BIO12) between 86.127 - 86.6264 mm.; annually maximum precipitation (BIO13) between 225.631 - 227.511; annually minimum precipitation (BIO14) between 2.84739 - 2.98439 mm.; precipitation seasonality (BIO15) between 70.3660 -70.9822 mm.
