Research results indicate that the climate of the Central Highlands region are complementary to a tropical monsoon climate of high mountains, there are two rainy seasons, dry clear, the total amount of radiation in a large (120-140 kcal/cm2), divided temperature according to altitude, rainfall and rainfall intensity is greatest in the rainy season. Based on the total heat in the target, average annual temperatures, the absolute lowest temperature in combination with average annual rainfall and coefficient of moisture in the dry season, the Central Highlands is divided into eight agro-climatic sub-regions different. Based on climate partition can carry out the distribution of plant structure as a significant resource of heat - moisture and is the basis for selection of plant structure and seasonally appropriate, to ensure the development of agricultural sustainable and ecoenvironmental protection.
