A few years' statistical climatic data in Zixi County were analysed, the results are as follows: In Zixi County the resources in light energy and heat energy are good, and the water resources are adequate. The average annual solar radiation is 100.7×4.1868KJ/ cm 2, and the average annual sunlight is 1 363 h, which is one of the minimal values in Jiangxi Province. The average annual temperature is from 16℃ to 18℃; January is the coldest month in a year, its average temperature is 5.7℃, and its average lowest one is 2.4℃; July is the hottest month in a year, its average temperature is 27.8℃, ant its average highest one is 34.4℃. The average annual rainfall amounts is 2 263.78 mm, but the rainfall varies significantly with seasons amassing in spring and summer. The climatic resources in the mountainous areas in the county are abundant, the types vary, so it can be divided into four climatic resource strata. They are the crop stratum, the cash forest stratum, the main forest stratum and the planned-exploitation stratum. The climate in the mountainous areas has the characteristics of multilayer, multiplicity, tridimensionality and multiadaptability. Some valuable, distinctive and first-qualified species have habitats in the special climatic ecological environment. Lovely climate in the mountainous areas is of great benefit to development of tour industry.
