Research on ecological and climatic regionalization for turfgrass in China based on ArcGIS

Climate is a dynamic combination of environmental factors that can affect lawn development and the turfgrass industry in China. In this study, six meteorological indexes, namely average annual temperature, average annual precipitation, July average temperature, January average temperature, July humidity, and January humidity were selected as indexes of ecological, climatic regionalization for lawns, and a lawn climate zoning map was completed by ArcGIS software. In the study, we divided China into nine eco-climatic zones for lawns, including the Qinghai-Tibet Plateau zone, Cool-semiarid zone, Cool-humid zone, Cool-arid zone, Northern transitional zone, Yunnan-Guizhou Plateau zone, Southern transitional zone, Warm-humid zone, and the Tropical and subtropical zone. The Yunnan-Guizhou plateau zone, the Warm-humid zone, and the Tropical and subtropical zone are the most suitable for warm-season turfgrasses, while the Cool-humid zone is suitable for cool-season turfgrasses. Turfgrass drought resistance is required for the development of the turfgrass industry in the Qinghai-Xizang plateau zone, Cold-semiarid zone, and Cool-arid zone. For the North and South transitional zones, the cultivation of excellent lawn turfgrass varieties and the development of advanced maintenance techniques are necessary.
